Steering Wheel Rotation Sensor Signal Check

  1. With control module connector disconnected, start engine. Using an analog ohmmeter set to 1-k/ohm scale, measure resistance between pins No. 1 and 5 and pins No. 5 and 6 while slowly rotating steering wheel.
    NOTE: Resistance values will vary between ohmmeters. Needle on all meters should swing from a lower to higher resistance and back, approximately every 9 degrees of steering wheel rotation.
  2. If meter needle swings for both circuits, steering wheel rotation sensor is functional. Replace EVO control module and re-test system. If meter does NOT swing for both circuits, proceed to QUICK TEST C4  .
