Name is***** goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back,

Hi .
For some reason my fellow expert opt out maybe he had to leave .

The code P0159 you got is your Bank 2 sensor 2 , this is on the firewall side of the engine bay , not the front ,and after the catalytic converter.

There is many causes that can trip this code but in almost all cases the sensor is the problem, as its become very lazy and is not switching in the set time it should.

Other possible cause for this code :

HO2S signal circuit is open or shorted to ground

HO2S element is contaminated or it has failed

HO2S heater is damaged or has failed

Intake air leaks, exhaust manifold leaks or PCV system leaks

MAF sensor out of calibration (it may be dirty or contaminated).

Please check this out and then get back to me if needed with the reply button, and not the poor or bad service, this way i can get back to you or suggest another expert if needed.

Your deposit does not pay me until the answer is rated in a positive way,
Not rating or a bad rating does not constitute a refund.

If you are not happy or you have sorted out your problem before the answer then please let me know with the reply button .

Kind regards Greg.
