Accelerator Pedal Position (APP) and Throttle Position (TP) Sensor Inputs
WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
APP SENSOR CHECK
| DTCsa | Description (Indicator Lamp) |
|---|---|
| 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). |
a 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. For additional DTC information, refer toDIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS .
TP SENSOR CHECK
| DTCs a | Description (Indicator Lamp) |
|---|---|
| P0122, P0123, P0222, P0223 | TP circuit continuity test (MIL, powertrain malfunction indicator [wrench]). |
| P2135 | TP to TP sensor correlation test (powertrain malfunction indicator [wrench], non-MIL). |
a 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. For additional DTC information, refer toDIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS .
