P0122 Jeep -

Question

HAD A CODE FIRST OF P0123 HIGH VOLTAGE CHECKED VOLTAGE - LINE VOLTAGE ( HOT) (KEY ON) IS 5.14 / SIGNAL IS .92 THEN OPERATED THROTTLE THUR RANGE GOOD AND STEADY BUT MAX WOT. IS 3.84

CHECKED ALL WIRES FOR SHORTS OR BAD WIRES (NONE) CHECK AT ECM STILL SAME CHECK WITH MULTIPLE TPS SENSORS (SAME )

NOW GETTING CODE P0122 LOW VOLTAGE?

THINK IT IS ECM

WHAT ELSE COULD I CHECK?

Answer 1

P0122 Throttle position sensor low input

Key on engine off and you get 5.14 volts is good. but the range is wrong it should be 0.26 volts and 4.49 at WOT.
