TP Sensor Out of Self-Test Range

2014-2014 Lincoln MKX 3.7L V6

Low SeverityPowertrain

The 2014 Lincoln MKX is equipped with a 3.7L V6 engine. Below you'll find detailed p1124 diagnostic code information including labor time estimates, cost ranges, and technician notes specific to this engine configuration.

Description

The Throttle Position sensor reading is outside the expected parameters during the KOEO or KOER self-test. The throttle may not have been fully closed during the test.

Symptoms

  • Check Engine Light
  • Self-test failure
  • Possible idle issues

Common Causes

  • Throttle plate not fully closed during test
  • Faulty TP sensor
  • Throttle body carbon buildup
  • TP sensor needs adjustment

Diagnostic Steps

  1. Ensure throttle is fully closed during self-test
  2. Clean throttle body
  3. Check TP sensor minimum and maximum voltage
  4. Inspect for binding throttle plate

Repair Notes

Clean throttle body. Ensure throttle is closed during test. Replace TP sensor if out of specification.
