Check engine light.

[dklassen]

My light came on today (03 Libby) and at the same time I thought I felt a little hesitation or miss. Checked the code and it was 122 TPS voltage low. Is this a DIY fix? Expensive?

Thanks!

probably just a bad tps or could be the wiring which isn't likely. you'd need the serv. manual to check the wiring so you know what wire should read what.

Yea, its fairly DIY if you know your way around the engine. Its on the throttle body.
