Crank Angle Sensor

  2. If code 42 is stored in control unit memory, it is an intermittent condition. See INTERMITTENTS in TESTS W/O CODES article. If code 41 is stored in memory, check ignition coil tach signal to control unit.
  3. If engine does not start, crank engine for at least 2 seconds. With ignition still on, enter self-diagnostics and check for code 42. See TESTS W/O CODES article in this section. If code is present, check harness integrity between sensor and control unit. If harness is okay, replace crank angle sensor.
