Having problems with your 2003 Volkswagen Jetta TDI ?
Could someone tell me what the error codes P0141 P0036 on a 2003 Jetta means? thx
The error codes you have are for the O2 Sensors. There is one before and after the catalytic converter. It is usually the first O2 sensor that is the problem because the second sensor is used just to verify the converter is working. The O2 sensors are usually $60 to $130 dollars depending on the type your vehicle uses. they are located on the downpipe on the exhaust system and the other is locted after the catalytic converter on the exhaust system. The O2 sensor not working will cause you gas mileage to be reduced because the car's computer will run the fuel mixter rich.
