PO158

[AFelix]

Another service code. Does anybody have a specific fix for a PO158 code?Thanks in advance for any assistance you can give.

If I remember you correctly you have a 2000 or 2001 maxima?? If so replace the rear O2's and have your ecm reprogramed for the new O2's. The program is neccesary to prevent the new O2's from burning up. The new program delays the intial amperage to the sensor to help dry out the moisture that may be built up on the sensor.

You are correct, it is an 01 maxima. Can you be more specific about which O2's need replacement. I know there are a total of 4.Thanks.

What does it cost to have the PCM flashed

[NISTECH]

The rear O2's. the one in the header pipe at the bottom and the one right below the cat on the front bank. this outta get ya in the right place. zerothread?id=120838 You are doing the 2 labeld "rear" in the picture. The reprogram depending on your dealers hourly rate will be about 1hr labor.

What part of Sacramento are you in? I work at the Elk Grove dealer.
