REPAIR INFORMATION:
1)
TEST # 1: If a faulty TPS is suspected and the ECM/TCM has no codes stored, conduct the following test for high idle:
^
Have the vehicle idling (with all accessories turned off), transmission in park (ATM) or neutral (MTM), and the hand brake fully applied.
^
Using the Hi-Scan Pro's flight recording menu, observe and record the TPS, Idle Switch Position and engine RPM.
^
Slowly operate the throttle cam to increase the engine speed to about 2500 rpm (use the Hi-Scan Pro to observe the engine speed).
^
Slowly release the throttle cam back to the idle position. Observe the TPS and engine RPM readings on the Hi-Scan Pro.
^
Repeat the above process 10 times.
