DTC P1124: Throttle Position Sensor A Out Of Self-Test Range

2011 Mercury Mariner Premier, 2.5 7, AWDSECTION DTC P1124: Throttle Position Sensor A Out Of Self-Test Range
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: 
  • Binding or bent throttle linkage
  • TP sensor not seated correctly
  • Throttle plate below closed throttle position
  • Throttle plate/screw incorrectly adjusted
  • Damaged TP sensor
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. This DTC sets if TP1 or TP2 is greater than the expected value.
Possible Causes: 
  • Accelerator pedal applied during KOEO or KOER self-test
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.

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
