Accelerator and Throttle Position (TP) Sensor Inputs

ACCELERATOR PEDAL POSITION (APP) SENSOR CHECK

DTCs (1)  
P2122, P2123, P2127, P2128, P2132, P2133 APP sensor circuit continuity test (powertrain malfunction indicator [wrench], non-MIL)
P2121, P2126, P2131 APP range/performance (powertrain malfunction indicator [wrench], non-MIL)
P2138, P2140, P2139 APP to APP sensor correlation (powertrain malfunction indicator [wrench], non-MIL)
(1) Correlation and range/performance - sensor disagreement between processors (PCM and E-Quizzer). Monitor execution is continuous. Monitor false detection duration is less than 1 second to register a concern. Refer to DIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS for additional DTC information.
THROTTLE POSITION (TP) SENSOR CHECK

DTCs (1)  
P0122, P0123, P0222, P0223 TP circuit continuity test (MIL, powertrain malfunction indicator [wrench])
P0121, P0221 TP range/performance (non-MIL)
P2135 TP to TP sensor correlation test (powertrain malfunction indicator [wrench], non-MIL)
(1) Correlation and range/performance - sensor disagreement between processors (PCM and E-Quizzer), TP inconsistent with TPPC throttle plate position. Monitor execution is continuous. Monitor false detection duration is less than 1 second to register a concern. Refer to DIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS for additional DTC information.
