What This Code Means

Malfunction Indicator Light (MIL) ON during active fault; Adaptive disabled; ECM uses default value for ECT sensor

Possible Causes

  • •ECT sensor voltage exceeds 4.950 volts while engine is running
  • •Faulty ECM
  • •Faulty ECM connection
  • •Faulty ECT sensor
  • •Faulty Harness
  • •Faulty connection to sensor
  • •Intermittent Problem
  • •Open ECT ground (5Vrtn1) circuit

Suggested Actions

  1. 1Check if DST displays ECT voltage greater than calibration limit with Key ON, Engine Off (System Mode = 'Stopped').
  2. 2Disconnect ECT sensor from harness, jumper across terminals at connector, and check if DST displays ECT voltage of 0.1 or less.
  3. 3Disconnect wire harness header from ECM, remove yellow lock from header, and check resistance between MAP input at ECM header and signal at device (Ensure resistance is <5 ohms. Probe on the side of the terminal to avoid spreading pins).
  4. 4Perform the On-Board (OBD) System Check.
