APP and TP Sensor Inputs
WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2008 Mercury Sable, 2008 Mercury Mountaineer, 2008 Mercury Milan, 2008 Mercury Mariner, and 2008 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.
ACCELERATOR PEDAL POSITION (APP) SENSOR CHECK:
| DTCsa | |
|---|---|
| P1575 (ETC system with a 2-track APP sensor) | APP sensor out of self-test range |
| P2122, P2123, P2127, P2128, P2132, P2133 | APP sensor circuit continuity test (powertrain malfunction indicator [wrench], non-MIL) |
| P2121, P2126, P2131 (ETC system with a 3-track APP sensor) | APP range/performance (powertrain malfunction indicator [wrench], non-MIL) |
| P2138 (ETC system with a 2-track APP sensor) | APP to APP signal correlation (powertrain malfunction indicator [wrench], non-MIL) |
a Correlation and range/performance - sensor disagreement between processors internal to the PCM. Monitor execution is continuous. Monitor false detection duration is less than 1 second to register a concern. Refer toDIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS for additional DTC information.
THROTTLE POSITION (TP) SENSOR CHECK:
| DTCs a | |
|---|---|
| P0122, P0123, P0222, P0223 | TP circuit continuity test (MIL, powertrain malfunction indicator [wrench]) |
| P0121, P0221 (ETC system with a 3-track APP sensor) | TP range/performance (non-MIL) |
| P1124 (ETC system with a 2-track APP sensor) | TP sensor out of self-test range |
| P2135 | TP to TP sensor correlation test (powertrain malfunction indicator [wrench], non-MIL) |
a Correlation and range/performance - sensor disagreement between processors internal to the PCM, TP inconsistent with requested throttle plate position. Monitor execution is continuous. Monitor false detection duration is less than 1 second to register a concern. Refer toDIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS for additional DTC information.
