Hi, I'm gettng a P0136 error in my 1995 Nissan Altima. The engine is 2.4L 4 cylinder. Question: Is this error upstream or downstream O2 sensor (if indeed the problem is the sensor)? I cleared the codes out and within 30 miles this code (P0136) returned. Thank you for your help. Fran xxxx

Hi My Name isXXXXX you for using Just Answer.comThis is a rear(down stream) O2 sensor code. It is a fairly common failure and will most likely need to be replaced. First check for any exhaust leaks before the sensor. If no leaks are found replace the sensor and clear the code.Ryan
