Code 11 - Crank Angle Sensor

NOTE: Refer to illustration for ECU connector and terminal identification. See Figure .
  1. Disconnect crank angle sensor. Connect voltmeter set to low volts AC scale between crank angle sensor terminals. Crank engine and ensure voltage fluctuates with RPM. If voltage does not fluctuate, replace crank angle sensor. If voltage fluctuates, go to next step.
  2. Disconnect ECU and crank angle sensor connectors. Measure resistance between ECU connector and crank angle sensor connector. See ECU CONNECTOR & CRANK ANGLE SENSOR RESISTANCE SPECIFICATIONS  table.
    ECU CONNECTOR & CRANK ANGLE SENSOR RESISTANCE SPECIFICATIONS

    ECU & Crank Angle Sensor Terminals Ohms
    Non-Turbo
    No. 1 (1) & No. 1 Zero
    No. 2 (1) & No. 2 Zero
    No. 3 (1) & No. 3 One (Max.)
    Turbo
    No. 4 (2) & No. 1 Zero
    No. 5 (2) & No. 2 Zero
    No. 6 (2) & No. 3 One (Max.)
    (1) Measure at ECU connector B56.
    (2) Measure at ECU connector B58.
  3. Measure resistance between crank angle sensor connectors and ground. If resistance is not at least one megohm, replace crank angle sensor.
  4. Reconnect ECU connector and measure resistance between crank angle sensor sealed terminal (Yellow wire) and ground. Less than one ohm should be present. Disconnect cam angle sensor connector and measure resistance between sealed terminal (Yellow wire) and ground. Less than one ohm should be present.
  5. If resistances are not to specification, repair harness and/or connector. If resistances are to specification, check ECU terminals for poor contact or replace ECU.
