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 want to update that i checked my fuse engine sensor in the engine bay and it was shot. i swapped it and ill let you guys know tomorrow if it cured my problems.
im still getting the codes. i cleared them but im now getting the codes again after a drive and i turned off and on.
any help?

can you see if anything in my tune relates to the codes being thrown
What RPM is the engine idling at? Check table C3907. You may need to adjust the TPS sensor if the throttle body is not stock. It should go from 0% to 100% as you go from idle to WOT. The MAF code will set if it is disconnected. The other codes are all O2 heater codes, check the power to the sensors.

in gear it should idle at 870 warm at operating temp. in park it should be at 860.
If the fuse was blown, did you find the cause of it... and is it blown again...?
Send me a pm with your exact location and phone number.
The O2 heater performance DTC's may be due to a poor ground connection.
The other two may be due to poor wiring.
The TP one may also be due to the sanity check table that Al referred to.
