if the o2 sensor is bad this will throw multipal codes when its really only one prob. start with replaceing the o2 sensor first. their is and up stream and a down stream sensors in the exhaust system
you un plug them and thay just unscrew out and scerew the new ones in now thay make an o2 sensor socket you can buy at any parts store for about 15.00. and the sensor can be quet exspensive. now as for haveing a shop do this will run about 120.00 for labor plus cost of parts. you can e-mail your number and i will call you if you need more help.
buy or borrow o2 sensor socket most auto stores let u borrow this tool or use wrench and its really a matter of jacking up and supporting van getting under van and removing o2 sensor from exhaust pipe and replace with new one
The code po133 means o2 sensor checked slow (response 1/1). You will need to replace the o2 sensor to correct the problem. You can purchase the o2 sensor yourself and replace it at home. It's no big problem in doing it yourself unless you want to take it back to the dealer. Hope this will help.
hi, the only way to really check the o2 sensor is buy removing it then running power through it but this can damage it further. The most common thing you will notice if the lambda sensor (oxygen sensor) when the car starts from cold and if it runs ok when you run the car upto temperature if when its hot the engine doesnt run correc then this is usually proof the o2 sensor needs replacing.
What makes you think the o2 sensor is gone and are you going on about the lambda sensor in the exhaust if not then im sorry but let me know then i can assist you further ok
