Other issue recently solved Honda CRV 2000 model.

It overheated on the way back from a village market (this happened on a Saturday).

The mechanic that was called checked and discovered that the coolant had completely evaporated from the radiator.

So he then remedied the customer by adding fresh water so he could drive home.

But he also told the client that he should return on Monday to change his gasket from the overheating incident.

The client agreed.

But the client also consulted me and so I asked for all the tell-tale signs of a vehicle that had so overheated that it could be scientifically proven that the gasket was indeed gone.

The client checked and those signs were non-existent.

Nonetheless I told the client to rigorously inspect coolant levels for the time being.

He did some days, and would skip other days.

I kept insisting that he do it daily, until he discovered that he actually had a bad radiator.

So he came in for radiator service.

What I found out was that he was using what has been referred to as colored water.

I strongly recommended that he get coolant capable of doing 5 years or 60,000 miles.

He objected due to cash flow concerns until his next paycheck.

So the compromise we agreed upon was the use of Total coolant until he musters up the funds to switch to the recommended long life coolant for this vehicle.

Pictures of the work done follow immediately below.

First lesson I learned about driving.

Speed is nothing without control.

He who can safely stop a car is better than he who can only move the car.

Painful loss of innocent souls

2004 Volkswagen Bora 1.6L Interim Diagnosis/Report

Whenever a Volkswagen vehicle can idle
BUT
the same vehicle fails to respond to accelerator pedal input
AND
either the oxygen sensor heater wires or signal wires have been frayed, cut, damaged or exposed in any way
THE VERDICT IS USUALLY THIS
that the 5V Drive-by-Wire (DBW) aka Throttle Driver from the ECU has been roasted by the 12V from the oxygen sensor heater.

Likely causes of this unfortunate event can include but is not limited to:

1. Improper exhaust installation/modification
2. Crumbling engine mounts
3. Installation of poorly manufactured universal oxygen sensor
4. time-worn OEM oxygen sensor wiring

This repair is not going to come cheap as the client needs to do the following:

1. Replace the oxygen sensors with new from Bosch
2. With the help of a digital multi-meter ensure that there are absolutely no shorts on the vehicle especially in any circuits that are currently blowing fuses
3. Program and install a new ECM (where is not possible to repair the one that came with the vehicle from the factory)
4. Run a Throttle Body Adaptation (TBA)
5. Try to see if the vehicle will accelerate
6. Install extra heat shrink tapes around the oxygen sensors to form a flexible loop and a heat shield at the same time
7. Add fusing to the oxygen sensor heater circuit to forestall another event of the ECU being roasted

The tell-tale signs of this misfortune are the presence of Accelerator Position Sensor (G79) Signal too high and Accelerator Position Sensor (G185) Signal too high and oxygen sensor DTCs.

This sad event occurs because the throttle pedal, the throttle body and the upstream oxygen sensors all share a 5V signal from the ECM.

Whether there will be a final report depends on the client funding the process so the above listed can be done.

It would seem to me that to all intents and purposes I have rightfully earned every cent of the funds allocated to the diagnosis of the faults of this vehicle.

uwemjack:
That was me!
Nice set up and a lot of critical car parts and accessories, oils, grease etc. Met your hubby too and would hold him to that Jamaican lunch.

Will be there next week to pick up my items.
Oh and safe delivery

Eyen Eka...you beat me to it.

I was targeting launch date.

Discussions have been opened concerning another engine swap gone wrong.

This time around it is a 2001 Volkswagen Jetta 2.8L VR6 that has given its owner tremendous problems and hypertension. The vehicle has been grounded for ONE whole year.

The list of problems include:

Faulty gearbox

Engine overheating

Blown head gasket

Cracked engine top

Injector nozzle fault

Mass Air Flow sensor fault

Spark plugs soaking oil

Our prospective client has spent, spent and spent until he is tired.

There are three possible solutions:

1. Rebuild the current engine (and take advantage of our 12 months/24,000 miles warranty + great peace of mind)

2. Install a tokunbo engine (which will come with the engine sellers usual 1 or 2 weeks guaranty + the heart in one's mouth)

3. Get a reconditioned engine from VW (with 3 year/36,000 miles warranty + cost of shipping same from either US or Europe)

This depends on the client though.

We have made it clear that we charge a flat rate for labor on engine rebuilds (N250,000.00) that does not include the cost of parts(rebuild kit). The cost for parts to be replaced will be determined following engine disassembly and inspection.

If he goes for option 2, then we will do our best to source for a decent Nigerian source but are constrained to providing no more warranties than the source itself provides.

It would most likely be cheaper to source for and install a tokunbo engine.

Following immediately below is the history of the vehicle to date:

PREVIOUSLY
Car starts
But car cannot idle
When the accelerator is released the engine would stutter and go off
But the car makes explosive sounds
To be able to drive it to his workshop, the electrician had to unplug the MAF sensor, only then was he able to drive it some 20KM to his workshop

Scanning brought out 7 different DTCs

The electrician then proceeded to replace injector nozzles, in collaboration with a mechanic worked on timing, replaced the MAF sensor, replaced the control relay, removed and replaced an adjuster where engine oil was leaking from.

CURRENTLY
Car starts
Car idles fine
Car is drivable
The car makes explosive sounds
And the plugs are soaked in oil

TheCar:
Baba mi, things change rapidly.

If you're in I.T or Technology related business, you need to stay updated.

Technology is distruping everything now. Even the Lagos Yellow Cab investors take a hit with UBER/Taxify coming in to challenge their monopoly. Now Yellow Cab has resort to violence against Uber/taxify drivers since they can't innovate and now they belong to the past.

Understanding your audience, market, customers' income and purchasing power is the only advantage you have over your business competitors.

The irony of our Nigeria economy is, factories shutdown and are being bought over by churches. People working in the factory lose their jobs and go back to the churches praying for jobs.

Everyone want to make fast money with little or no work, hence the rapid rise of fraudsters and sports betting companies.

To stay relevant in business, diversification is the way out. Even Nigeria richest according to Forbes, also diversify to stay relevant.

Two parts to the disruption technology and government policy.

Uber and London, even uber in other parts of the world.

Technology is right now disrupting automotive service. Mechanics are a dying breed. Enter Technicians.

Even Uber continually adjusts to market conditions, so I would advice owners and drivers to do the same.

E.g., why not use full synthetic and extend oil drain intervals after doing your research?

Those big companies are ruthless with their cost cutting measures, so should you.

It is easier to keep the money in your pocket from going out than it is to earn an equivalent sum.

Finally, be open to diversification.

I need not go too far a very vocal voice on this thread has diversified a lot, you can learn from him.

TheCar:
Please when you get back on your feet in the business, kindly diversify your interest.

The rapid fall of Naira against USD affect everyone purchasing power hence certain things were deemed to be luxury.

Also no matter how good and well sales follow your way, never forget to do continuous "Customer Spending Behaviour" Analysis.

During the period, a lot of States can't pay salaries hence a huge portion of the "Spending" population were broke.

A diversified portfolio would help you mitigate against such trend in the future.

Macro Economics affect everybody because we neglect politics.

I don't like Politics, but believe it or not, Politicians control the economy.

Nicely put.

Study the annual reports of companies.

Take PZ Nigeria PLC for example.

They were hit real bad.

But there has been a rebound for them.

My company (dual registered in Nigeria and the US) was hit below the belt.

I come from an IT background and delivered a variety of solutions to the FG and a couple of private sector firms large and small including the top tier construction firms.

Then things tanked.

Even PZ Nigeria PLC had to diversify and change market strategy...and this is how in summary AutoElectNG was born.

So I tell whoever cares to listen diversify and never let one income source provide more than 50% of your earnings.

I don't know if it's American or European. How do I check? It was the from shocks I changed.

I need your VIN. I also want you to tell me if it were front or rear shocks

empron:
Simple fact.well done.I have been trying to reach you on your WhatsApp number.pls kindly send it.

drmuchin:
It is rare to see a Nigerian share information like this

Picture below explains my background.

I have been privileged to associate with people who ordinarily I would have no access to except that they come from a culture of sharing knowledge...to give just one example, how easy is it to have access to the wealth of knowledge and experience of a NASA trained scientist (20 year veteran) and automotive aficionado who selflessly explained concepts I had difficulty grasping until it made sense to me?

Until the value of teamwork and knowledge sharing is valued here as it is valued over there...progress will be difficult.

The other part of my background is that my dad used to tell me if you understand it, then explain it to me in your own words, not the words of the text you claim to have understood.

When I am not willing to burn brain cycles to explain in my own words, I find a text that appropriately explains the concept I want to pass on and provide appropriate attribution

I have been a victim. If your vehicle malfunctions on Airport Road or Kubwa Road at night in Abuja, just lock it, take your phones or other carryon valuables and flee.

Go and get a towing van and a detachment of police to come with you before approaching your vehicle if your value your life.

I lost my phone, I was fortunate not to lose anymore.

Another lady whose vehicle malfunctioned some minutes later lost her phone, her mum's phone, her friends phones, lots of cash and gold ornaments.

A word is enough for the wise.

This is the truth...and it is gospel...the story is not false.

Until it happened to me I never believed it could happen.

The third aficionado test cannot be done yet, because the ECU is not on the vehicle. We are investigating the possibility of repairing the ECU since it appears to be bad. Test will be conducted upon return of the ECU.


P1631: Throttle Position (TP) Sensor -G79- Signal too high


Using a Digital Multimeter, measure the voltage drop between the following:

PIN1 and the 5 volt reference from ECM for G185

PIN2 and the 5 volt reference from ECM for G185

PIN3 and the sensor Ground circuit for G79

PIN4 and the sensor Signal circuit for G79

PIN5 and the sensor Ground circuit for G185

PIN6 and the sensor Signal circuit for G185

P1631: Throttle Position (TP) Sensor -G79- Signal too high

Remove the ECM

Then check the Throttle Position Sensor TP (G79)/Accelerator Pedal Position Sensor APP (G185) 6 pin electrical harness connector terminals to the ECM electrical connector T121 for an open circuit

Test the following pins

TP/APP Harness connector **//** ECM Harness connector
1 **//** 72
2 **//** 73
3 **//** 36
4 **//** 35
5 **//** 33
6 **//** 34

Expected value must be less than 1.5 ohms


Results obtained


1 **//** 72= infinite resistance
2 **//** 73= infinite resistance
3 **//** 36= infinite resistance
4 **//** 35=infinite resistance
5 **//** 33=infinite resistance
6 **//** 34=infinite resistance

It would seem that these test results are NO GOOD

P1631: Throttle Position (TP) Sensor -G79- Signal too high

Confirm that battery voltage is a minimum of 12.5V
Confirm that all electrical loads are switched off
Confirm that GROUND connections between the engine, the transmission and the chassis are OK

Remove the driver side footwell

Disconnect the Throttle Position Sensor TP (G79)/Accelerator Pedal Position Sensor APP (G185) 6 pin electrical harness connector
THEN
Switch the Ignition ON

Using a Digital Multimeter, measure the voltage drop between the following:

PIN1 AND GROUND
PIN2 AND GROUND
PIN2 AND PIN 3

If OK, should read about 5V.


These were the results of our factory voltage drop test

First test (PIN1 AND GROUND) = 5.08V,

Second test (PIN2 AND GROUND) = 5.00V,

Third test (PIN2 AND PIN 3) = 4.99V

It would seem that these test results are good

AutoElectNG:
P1631: Throttle Position (TP) Sensor -G79- Signal too high

This code is an indication that the vehicle is afflicted with the take me home aka limp home mode.

Once this condition occurs, nothing will make a VW rev up!

Is there a problem with the connections to this module? Do the contacts suffer from dirt and or corrosion causing the voltage and or current flowing to be out of sync with factory specifications? Is the accelerator pedal itself bad?

Our tests will reveal the next course of action.

These tests have to be redone. Then will update this post.

There are two tests mandated by the factory to determine the way forward. There is a third test suggested by VW diehards.

The first factory test is voltage drop testing. The second factory test is a measure of resistance. The third aficionado test is a voltage drop test

GAZZUZZ:
What do you do when a good driver goes bad?

One of my best started defaulting and now owing 3weeks. Father of 3 consistent payments since January.

Be understanding...give him time...how much is up to you...investigate...find out why, if you can help then good

Update on the 2004 Volkswagen Bora

Final tests carried out...will update post soon with the results and the implications of the same...work takes second place over the weekend. ..

Chuwaa:
Drivers watch out o!

Wale Babalakin is the prime promoter of the firm running the airport.

He is a lawyer, I am beyond shocked.

This is a problem of transportation business everywhere in Nigeria, big buses, small buses, taxis old and new suffer this kind of fate day in day out

The Twitter guy was really nice by the way

thebigkendo:
Truth be told, if I were in his shoes.. used ECT2 + reverting fans back to factory for N30,000.. I no go gree too..

NB: Did you test if his ECT2 was actually bad? Might just be that Kazeem butchered the wire to the Sensor.

Picture you attached is ECT1 and is not related to the P2185: Engine Coolant Temperature Sensor #2 Circuit High Input


Sensor #2 on that Honda located at bottom of the radiator.

"sensor circuit high input" my bet is on an open circuit

I didn't say 30,000.00 he said he has only 30,000.00 for everything.

I started way way higher.

When he said not so boxed up I then said in that case ignore A/C and fix ECT, thermostat as well as fans and your fuel consumption should normalize.

He didn't even agree for factory data so I have not crosschecked which sensor is which.

My time should be paid for unless I decide I want to do pro bono

thebigkendo:
owner na really alaroro



A/C parts alone already over N40,000

I offered to fix just a used ECT and revert fans to factory he insisted A/C must be included or no deal

Missing detail ?

Make and Model?

timifakay:
Boss, calm down first, in this our Nigeria, many are mad, but few are roaming.

@thebigkendo GIGM is #8450 one way. Baba Diportivo no go sleep and do a lil pepper souping after work?

Surprising thing is prospective client said he found the parts for less than 20,000!

1stNumeroUno:
Oga Gaz.zuz,

My bank type corolla has been shorting oil recently. To my amazement my mechanic said that's the early sign that the engine is going off.
I need advise, is there a type of oil you'll suggest for me now considering the new 'status' the car want to attain soon ( I use Mobil 1 presently).
Also, are there things I should watch-out for as I'm planning to travel this weekend (my first with the car).

Many thanks.

With all due respect to Gaz.zuzz

So your trip doesn't turn out to be a disaster.

Top up the oil, make sure it is at the maximum.

Buy a 4 or 5 liter can of the same oil put in the car storage compartment

Every time you stop to refuel please check your oil...oh its a corolla so stop to check oil level even if you don't refuel every 200 kilometers

Is it a 2000 to 2002 model?

Best of luck.

Do same to coolant ensure it's at maximum before you leave.

taxiappguy:
Thanks. I've been meaning to educate myself on this topic.

My pleasure
