P0122 is a code for Throttle Position Sensor Circuit low input. If you want to troubleshoot this you will need a multimeter. Do you have one? Is your car idling rough, stalling or driving funny?

The MAF isn't the problem if the code is P0122. P0122 is a code for Throttle Position Sensor Circuit low input and AFAIK the best way to troubleshoot this problem is with a multimeter. Do you have one?

You can't just go replacing parts without troubleshooting first. That's why I've asked you if you have a multimeter two times.

It could be something simple and the only way to figure it out is by taking readings with a multimeter.

I've been very busy the last week but I'll try to post the way to troubleshoot this problem tomorrow. I have the manual on my hard drive but I'm not exactly sure what I need to do to make a non PDF file that I can post. I know I can print a copy and scan it but I'm out of black ink right now.

I'll do my best to get it to you ASAP.
