Accelerator and Throttle Position (TP) Sensor Inputs

WARNING: This page does not describe the selected car, but rather 35 other vehicles, including the 2007 Mercury Mountaineer, 2007 Mercury Monterey, 2007 Mercury Montego, 2007 Mercury Milan, and 2007 Mercury Mariner. However, it is still accessible from the selected car via links, so may be relevant.

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.
