Moderate SeverityChassisGeneric (SAE)

The 2018 Lincoln MKX is equipped with a 3.7L V6 engine. Below you'll find detailed c0155 diagnostic code information including labor time estimates, cost ranges, and technician notes specific to this engine configuration.

Description

The torque sensor that monitors regenerative braking output is reporting invalid data.

Symptoms

  • Regen braking warning
  • Reduced energy recovery
  • Braking force inconsistent
  • Hybrid efficiency reduced

Common Causes

  • Faulty regen torque sensor
  • Sensor wiring damaged
  • Motor-generator feedback fault
  • Sensor connector corroded

Diagnostic Steps

  1. Read regen torque sensor data during braking
  2. Compare motor-generator actual torque to commanded
  3. Inspect sensor wiring
  4. Check sensor connector
  5. Test sensor through full range

Repair Notes

Replace regen braking torque sensor. Recalibrate after replacement.
