we put a brand new delco tps on the car. cleared the code with snap on. but it only sets the code when at the track in staging lanes. dont understand y it only does it there or anywhere. i have a hard time believing a delco sensor is bad. but things do happen. any help is appreciated

under diagnostics is there a tps p0121 min and max map test. If so increase this value to 75 and 65

10secopcar

so set the min to 75 and the max to 65 or switch them? so this is just a test parameter?

switch em and yes it is just a test parameter. Its the min and the max values the PCM uses to run the test TPS% vs engine rpm. With a cammed car they wont match anymore and you have to either desensitize the test (EFILive has tables for this) or change the test values (Edit and HPTuners)

is it possible that having the cutout open is affecting this in some way? and when i change it seems how its just a test aprameter it wont affect anything else correct

cutout wont do anythign its just a test that is failing. its a tps vs rpm test.

You can find a good amount of info on the P0121 code right on our forum
