P1120 - THROTTLE POSITION SENSOR A OUT OF RANGE LOW (RATCH TOO LOW)

Description:	The throttle position (TP) sensor circuit is monitored by the powertrain control module (PCM) for a low TP rotation angle or voltage input below the closed throttle position through the comprehensive component monitor (CCM). The test fails if the TP rotation angle or voltage remains within the calibrated self-test range, but falls between 3.42-9.85% (0.17-0.49 volt).
Possible Causes:	TP circuit with frayed wires Corrosion or loose connection on the TP circuit connectors and pins VREF open to TP sensor VREF short to SIG RTN
Diagnostic Aids:	A TP PID (TP V PID) between 3.42 and 9.85% (0.17 and 0.49 volt) in key ON, engine OFF or key ON, engine running indicates a concern is present.
Application	Key On Engine Off	Key On Engine Running	Continuous Memory
