I bought my 2003 Yukon about a year and a half ago and within a month of owning it I started getting Reduced Engine Power on the DIC and a check engine light would come on. I found out the code was P1125 "APP (Accelerator Pedal Position) does not match TPS (Throttle Pedal Position". This happened about 4 times and then went away without me doing anything really. Hasn't shown up since last summer.
However, recently I did some data logging for my Black Bear Tune and noticed I could map my APP sensor against my TPS sensor and graph the data from the two sensors using the data logging tool. Very cool. So here are my results....
It looks like the TPS sensor never goes to 0%, always hangs out at around 11%. Other than that, the TPS and APP are pretty spot on with each other. Maybe I just need a new TPS? Anyone have any suggestions?
