DTC P0068: Throttle Position (TP) Sensor Inconsistent With Manifold Absolute Pressure (Map) And Mass Air Flow (MAF) Sensors

WARNING: This page is about a different variant/trim than selected.

P0068 - THROTTLE POSITION (TP) SENSOR INCONSISTENT WITH MANIFOLD ABSOLUTE PRESSURE (MAP) AND MASS AIR FLOW (MAF) SENSORS

Description:	The PCM monitors a vehicle operation rationality check by comparing sensed throttle position to MAP and MAF readings. If, during a KOER self-test, the comparison of the TP, MAF and MAP sensor readings are not consistent with the calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.
Possible Causes:	Air leak between MAF sensor and throttle body. TP sensor not seated properly. Damaged TP sensor. Damaged MAF sensor. Damaged MAP sensor.
Diagnostic Aids:	Drive the vehicle and exercise the throttle and the TP sensor in all gears. A TP PID (TP V Aids: PID) less than 4.82 percent (0.24 volt) with a LOAD PID greater than 55 percent, or a TP PID (TP V PID) greater than 49.05 percent (2.44 volts) with a LOAD PID less than 30 percent indicates a hard fault.
