Accelerator and Throttle Position (TP) Sensor Inputs

WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2005 Mercury Sable, 2005 Mercury Mountaineer, 2005 Mercury Monterey, 2005 Mercury Montego, and 2005 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 (ETC lamp, non-MIL)

P2121, P2126, P2131

PP range/performance (ETC lamp, non-MIL)

P2138, P2140, P2139

APP to APP sensor correlation (ETC lamp, 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 malfunction. Refer to POWERTRAIN DTC CHARTS AND DESCRIPTIONS - GASOLINE MODELS for additional DTC information.

THROTTLE POSITION (TP) SENSOR CHECK

DTCs ⁽¹⁾

P0122, P0123, P0222, P0223

TP circuit continuity test (MIL, ETC lamp)

P0121, P0221

TP range/performance (non-MIL)

P2135

TP to TP sensor correlation test (ETC lamp, 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 malfunction. Refer to POWERTRAIN DTC CHARTS AND DESCRIPTIONS - GASOLINE MODELS for additional DTC information.
