DTC P1124: THROTTLE POSITION SENSOR A OUT OF SELF-TEST RANGE
| For Ranger | |||
| Description: | The throttle position (TP) sensor circuit is monitored by the powertrain control module (PCM) for an out of range TP rotation angle or voltage input. The test fails if the TP rotation angle or voltage reading is less than 13.27% (0.66 volt) or greater than 23.52% (1.17 volts). | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | The TP PID reading not between 13.27-23.52% (0.66-1.17 volts) in ignition ON, engine OFF or ignition ON, engine running indicates a concern is present. | ||
| For All Others | |||
| Description: | During key on engine off (KOEO) and key on engine running (KOER) self-tests, the powertrain control module (PCM) monitors the electronic throttle control (ETC) throttle position (TP) sensor inputs to determine if the TP1 and TP2 signals are less than an expected value. If either TP1 or TP2 is greater than the expected value, the DTC is set. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | Repeat the self-test without applying the accelerator pedal. Make sure the floor mat is not interfering with the accelerator pedal. Diagnose any TP circuit DTCs first. | ||
