Exclamation Ever since i did my 98 to 02 pcm conversion i get the following codes.

its making me nuts.

p0121 p0102 p0135 p0141 p0155 p0161


any ideas?

the tps code i have an idea it can be the throttle position sensor. it should read at .4 when foot is off the gas on idle. but it reads 0% am u correct in assuming it should be at .4?


please any info would be greatfull. i need these codes off of my pcm its driving me nuts with the ses light on.

I'm guessing it's a wirng problem

Yeah who cares about the O2 sensor stuff just disable all that run open loop speed density then you only need to sorry about the p0121 error

... or fix the wiring and run open loop speed density anyway...
