music aint feeling dis tonto dike chic! maybe she should try Gospel...
The Lord is merciful and will accept her

ray collins: Update- black sooth notiiced at exhaust tail pipe tip. Code is still P1135 and now P1346. Does a bad air fuel sensor make a car smoke black? Whenever I rev dis car no smoke @ all but just noticed black sooth @ d tail pipe exhaust end. Inputs needed to solve dis problem. Maybe I will check my injectors. But d car performs fine . No performance issues except a lil drag when d AC is switched on as dis decreases thr rpm value but stabilizes after some time.

Oga , U said the car performs fine , if u continue scanning that car daily codes will always definitely come up(bros that car isn't a new car anymore)...free your mind and psyche abt the fuel economy if not BP Looms..

Costee: Car-doctor certainly made a good observation concerning the duo-codes of P0130/P0135. At all events, your issue is not that difficult to resolve. Call this number 08138639666. The guy's name is Shakiru. He's an auto electrician and I'm sure he'll get it sorted out.

thank you @ costee... God bless., I will check the fellow by weekend and give u an update

[quote author=car-doctor]P0141 OBD-II Trouble Code

Technical Description

O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)

What does that mean?

This code means that the heated circuit in the oxygen sensor on bank 1 decreases time needed to enter open loop.

As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. If the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0141.

Symptoms:

You will likely notice poor fuel economy the illumination of the Check Engine Light.

Causes:

A code P0141 may mean that one or more of the following has happened:
•Open or short to ground in the wiring harness
•O2 heater circuit wiring high resistance
•O2 heater element resistance is high
•Internal short or open in the heater element

Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.

Possible Solutions:
•Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
•Repair short or open or high resistance in wiring harness or harness connectors


The correct DTC number for your second and third fault codes are P0130 and P0135 (Not P01130/ P01135). They are both similar generic codes.

P0130/ P0135 - 02 Sensor Circuit Malfunction (Bank I Sensor 1)

OBD-II Trouble Code Technical Description

02 Sensor Circuit Malfunction (Bank I Sensor 1)

What does that mean?

The O2 sensor produces a voltage based on oxygen content in the exhaust. The voltage varies between .1 and .9 Volts, .1 indicating lean and .9 indicating rich.

The ECM constantly monitors this voltage while in closed loop to determine how much fuel to inject. If the ECM determines that the O2 sensor voltage was too low (less than .4 Volts) for too long (for more than 20 seconds (time varies with model)), this code is set.

Potential Symptoms:

Depending if the problem is intermittent or not, there may be no symptoms other than MIL (malfunction indicator lamp) illumination. If the problem is constant, then symptoms may include one or more of the following:

•MIL illumination
•Engine runs rough, missing or stumbling
•Blows black smoke from tail pipe
•Engine dies
•Poor fuel economy

Causes:

Usually the cause of P0130 is a bad oxygen sensor, however this isn't always the case. If your O2 sensors haven't been replaced and they are old, it's a good bet that the sensor is the problem. But, It could be caused by any of the following:

•Water or corrosion in the connector
•Loose terminals in the connector or severed wires.
•Wiring burnt on exhaust components
•Open or short in the wiring due to rubbing on engine components
•Holes in exhaust allowing unmetered oxygen into exhaust system
•Unmetered vacuum leak at the engine
•Bad O2 sensor
•Bad PCM

Possible Solutions:

Using a scan tool, determine if the Bank 1, sensor 1 is switching properly. It should switch rapidly between rich and lean, evenly.

1. If it does, the problem is likely intermittent and you should examine the wiring for any visible damage. Then perform a wiggle test by manipulating the connector and wiring while watching the O2 sensor voltage. If it drops out, fix the appropriate part of the wiring harness where problem resides.

2. If it doesn't switch properly, try to determine if the sensor is accurately reading the exhaust or not. Do this by removing the fuel pressure regulator vacuum supply briefly. The O2 sensor reading should go rich, reacting to the extra fuel added. Reinstall regulator supply. Then induce a lean condition by removing a vacuum supply line from the intake manifold. The O2 sensor reading should go lean, reacting to the enleaned exhaust. If the sensor operates properly, then the sensor may be okay and the problem may be holes in the exhaust or an unmetered vacuum leak in the engine (NOTE: Unmetered vacuum leaks at the engine are almost always accompanied by lean codes. Refer to the appropriate articles for diagnosing an unmetered vacuum leak). If the exhaust does have holes in it, it's possible that the O2 sensor may be misreading the exhaust because of the extra oxygen entering the pipe via those holes

3. If none of this is the case and the O2 sensor just isn't switching or acts sluggish, unplug the sensor and make sure there is 5 Volt reference voltage to the sensor. Then check for 12V supply to the o2 sensor's heater circuit. Also check for continuity to ground on the ground circuit. If any of these are missing, or aren't their proper voltage, repair open or short in the appropriate wire. The O2 sensor will not operate properly without proper voltage. If the proper voltages are present, replace the O2 sensor.


Car-Doctor.[/quote]@ car doctor , iam highly grateful for your comprehensive analysis , from all my deductions , it seems the problem is the oxygen sensor(only one)? in the exhaust?\
is it possible that bad plugs and leaking exhaust can cause poor economy and non-smooth driving?
NB : my panel beater has sealed two leakage spots in my exhaust pipe last two months? can I continue using it if another leakage is detected because I plan on giving the car to the mechanic by wednesday

Costee: There should at least have been some description of the codes. Well, the last two codes are non-existent. Check again. You should have 5 characters not 6. The first refers to your oxygen sensor under the car. The other two are presumably P1130 and P1135 for Air/Fuel Ratio sensors. In which case it does appear you need to change or check the connections of both of your A/F (upper) and oxygen (lower) sensors.

@ Costee, thanks for ur observation and contribution, pls I need suggestion for a good mechanic to fix /check the sensors for me.. I live in lagos (ikeja)

oga ikenna, Siena and car doctor pls help ur boy

I recently noticed that my car (Toyota camry 1998) drives rough and its very fuel thirsty. So I took it for vehicle scan diagnosis and some codes came up viz: P0141, P01130, and P01135 came up .please I need the help of auto gurus to help me with the meanings and correct expertise to rectify them . thanks in anticipation

RIP TO THE DEAD KIDS, I WONDER WHEN THE RULE BANNING THIS BLOODY TRAILERS DURING THE DAY WOULD BE IMPLEMENTED

the last refrigerant used for my car is called "snow".. the ac technician claimed its a new product but am not satisfied with the cooling since the gas that came with the car finished... please my dear friends suggest for me the best refrigerant for optimum cooling in Toyota 98 camry...thanks

me2me: @ ikenna351 & smartchoice

So far so good, the AC is performing well. Am still test running though..

which refrigerant was used for u now , becos am not impressed with refrigerant used in the top-up of my tiny light camry

me2me: @ jayriginal

The AC still chills in the afternoons..test running is still on-going..

which refrigerant is the best to use in a tiny light camry?

used by a woman ?? it makes me not interested again

lemme give u 455k for this car last price

pls how much will it cost me to oven-bake my camry tiny light ?

this ur tokunbo naija used car sef the price is too cheap
