This is an intermittent issue I have scoped out the accelerator pedal and tps sweep all looks good , Engine goes into reduced power mode problem occurs after hitting bumps, I have checked a wire harness going to the throttle position sensor no issues , I'm leaning towards changing the app But I want to be 100% sure the APP 2 didnt look as perfect as app 1 on scope , but i could Never catch it acting up only until I drive it and hit bumps above picture is a snapshot of tps Desired not Matching the actual percentage of throttle ideas?

In PID APP2(V) the min - max range reads 0.06-2.06. The min is too low I think. The condition for setting the dtc is "app sensor 2 voltage is less than 0.325 volt for more than 0.4 seconds"
Tried the tap test, surely that must make the app sensor act up?

With drive by wire I always make sure to take the throttle body off and clean it real good before replacing any parts

Hi, did you find the solution to your code p2127? I’m having the same exact problem after hitting a bump on my 07 avalanche and it’s driving me crazy. Thank you
