Ikenna351:

You dey ask me? Lol! Thats the least price i could get it here in Abuja. Painful, but what can I do.

And yes, the ES9J4S thermostat is different from EW10 thermostat. Their part numbers differ and both have different shapes. Though, the EW10 thermostat would be cheaper. But ES9J4S and EW10 use the same CTS. The price is 4k.

The truth is, 406 original parts are pricey. For example, the front brake pad (PAN) cost 10k or so. Though, we have the one of 5k and 2k.

Ikenna.

yanmata: @ikenna n others, I own a pug 407. I have no issues with the car except one major issue. The issue is, the average fuel consuption from the dash 32mpg on highway n 11mpg in town..

What could be d major difference in fuel consuption In practical terms, I observed on stationay position with the ac put on, the fuel comsuption is something else. However, on highway, it consumes normal at an average of 10lts/100km which to me is on the average.

What could be the reason for this anomaly? Thx guys.

Ikenna351:

Even your 10 L/100km or 32mpg on highway is not normal.

I got 39 mpg (about 7 L/100km) 3 days ago on an expressway in Abuja in my D9 V6, with the AC on. So if my V6 can get more mpg than yours (which i believe is I4), then something must be wrong. Even in the city, last time i checked, i was getting 22mpg with the D9 v6, with the AC on.

If your check engine light is not on when engine is running, something is still wrong. Hope your brake is not binding? Hope you havent removed the cooling system thermostat? Hope your tyre(s) is not underinflated?

What engine is it, anyway?

Ikenna.

yanmata:

@ikenna, the pug runs on ew12. The checked engine is on. The car is scanned by a chap @asd motors...the culprit they said is the throttle n won't pose any issue. No black smoke. Two abs sensors are said to be bad....the three are well inflated as its factory specified type.

Ikenna351:

By throttle, you mean Motorised throttle body?

Did the ASD motors guy scan the car with PP2000 or just with unversal scanner?

Ikenna.

yanmata:

He said its d throtle don't one if its d motorised. But 1 think I know about the throtle of this is that it does not d conventional throthle...iys all electrical.

As for d scanner used.the scanner has the pug n citron logo attached to a laptop.

yanmata: How do I test these values as am not an autotech guy

There is a single fan than turns on only at intervals...

Don't think the thermostat is tempered with coz I cleared the car from port myself n drove it down to Abuja. No mechanic has touch d car apart from my first service.

hope I answered ur queries.

Ikenna351:

Also, about the CTS, its also better to test it with DMM when the engine is still cold. Otherwise, i would have asked you bring the car to my place for me to do it for you, since you stay in Abuja too. But if you still want to come, send me a mail so that i direct you.

Thx ikenna. I will do exactly what you directed first thing tomorrow morning and revert to you.

Best of wishes.

Ikenna

emychukwu: Like dey have some selected people dat dey reply on dis thread..jisi ike

emychukwu: Fuel hose replaced...but pls y do my engine go down or vibrate each time I on d ac...wot number is d rpm pin supposed to be wit ac and without ac. Thanks as I await ans

yanmata:

Morning Ikenna,

I have started my 407 and observed the tempertures of both the upper and lower horses and they both seems to worked very well as described by you. Intact it took the engine about 10mins before the fan begins to rotate at speed 1 while my temp gauge remain at 90.

Meanwhile b4 I switch off the car the readings from dash shows 39mpg and 12mpg respectively. No traces of black smoke from the exhust n no missing or hesitating to start or jerking of any type at all.

These are my submissions Ikenna.

bioye: Hi guys. I'm honoured to be a member of this cliche. I own a 406 - 2.0L (136bhp) - EW10J4 - R6F. Sadly after serious abuse by my last mechanic some days ago, the car is now in a virtually undrive-able state. I'm sure if the car was owned by car enthusiasts like you guys, it would the back on the road with minimal effort.

Anyways, before the last trip to the mechanic, the car was fine except that it was emitting thick black smoke and whenever I switch on the AC, I get the message "engine coolant temperature too high" after a few minutes. I had earlier gotten advice from various quarters to:
1. get a new engine
2. buy a half engine
3. change the catolic sensor (which I now believe to be the catalytic converter)

However, this last mechanic assured me that he would ring the engine(20k), change the top gasket(5k) and replace the oil and all the problems would disappear. He said if I brought the car in the morning, it would be ready in the evening. However, the car wasn't ready until 5 days later.

When I tested the car, the exhaust was still emitting thick black smoke. After driving for a few minutes (without the AC), I started getting the message "Oil pressure too low" and then "Engine coolant temperature too high" and to STOP. Then the gears became very hard and I had to use excess force to switch gears. I had to stop the car 3 times before I got home.

I would love to enjoy my Peugeot the way you guys do. I am tired of mechanic headaches. I know nothing about cars and I need help! Thank you in advance.

bioye: Thank you Ikenna for the quick response. Guess what, I was already planning on saving 150k for a new engine. Though I was also thinking that as long as I rely on these 'wack' 'mechanics', I would end up in the same situation.

Yep. I stay in Abuja - Apo Legislative Quarters. I believe by DMM, you mean Digital Multimeter. I don't own one and guess I have to learn to use it. Online, I see I can get it for about $20. Can you recommend where to get one in Abuja and how much?

How do I confirm the extent of havoc the mechanic has wrecked on the car? Are there physical inspections I can carry out or do I need to run a diagnostic tool on the engine? Though the dashboard shows enough oil, when I gauged the oil it was too low. Should I top the oil or carry out certain checks first?

Ikenna, would you be willing to look at the car? That's if I can get the car into a drivable state first without causing more harm. Thanks man.

wisesystem:

Been following ur posts and must say its really sad what our brodas on the road sides and garages have done to ur car. Well,the bright side is in the obvious fact that u are intent on not repeating those mistakes and are eager to learn... hence ur participation on this thread. Wish u the best in search for a new life for ur lion & good thing u ve hooked up with Ikenna da Lion King. Kindly update the house on ur the progress with ur lion so we all can learn or add to our existing knowledge. Av observed that most house members dont update the house on how well they were served by useful tips got from the thread which would otherwise have served others.

@ Ikenna, kindly indulge us with the technicalities involved with Bioye's Lion so we can learn. Hard to imagine a CTS fault can degenerate this bad!

Ikenna351:


To the best of my knowledge, CTS is the only injection sensor that reports to ECU the Coolant temperature. So, for him to be getting "Coolant Temperature too high", thats the only sensor i could think of for now.

A cold engine needs excess fuel to be able to start and run. The CTS makes that happen. When you switch on the ignition, the CTS will signal to ECU the temperature of the coolant. Then the ECU will use the signal/vlues it receives from the CTS to determine amount of fuel the injectors spray into the combustion chambers via intake valves. If the signal it receives from CTS is 3 volts, the CTS will command the injectors to spray in excess fuel for the engine to be able to start. 3 volts value from CTS means engine is coolant/engine is cold. As the engine is running, the coolant is getting warm and hotter quickly, made possible by Thermostat. As it coolant gets hot, the CTS volts value reduces upto 1 volts or a little less than 1 volt. At such value, the ECU will reduce the amount of fuel the injectors spray in (closed loop). Thats why when you remove and run your engine without thermostat, your CTS will always be reporting or sending high volt values to the engine ECU, making the ECU to be commanding injectors to be spraying in excess fuel. ECU works or manages the engine with signals it receives from various injection (and ignition) sensors/components.

Oxygen sensor comes in to perform its function when CTS must have done its part when engine its started for the first few minutes of engine running. Oxygen sensor has to heat first before it can work. Thats why the universal 02 sensor has heater, while the non-universal o2 sensor is mounted closer or on exhaust manifold for it to heat faster. So, while oxygen sensor is heating, the CTS is taking care of the required fuel the engine needs at every coolant temperature, before the o2 comes in to function. The functions of other fuel consumption controlled sensors (MAF/AFM/MAP, IAT, etc) are left out in the above explanations.

To understand me better, locate your CTS (its a sensor with green plastic connector near Thermostat housing), pull out the connector, start the engine, go the tail of your car and see how black the smoke your exhaust will be emitting

Ikenna.

bioye: Guys, I really feel at home here. Yep, I'm definitely eager to learn and I promise to keep the house posted with 'my progress'. Ikenna, apologies. I had to run some errands and I'm just getting to relax now. I'll buzz you and send the info you requested. Hopefully, we can hook up sooner rather than later. Many thanks!
