Control Solenoid Circuit Check

  1. Shift transmission to Park or Neutral. With engine at idle, disconnect engine mount control solenoid harness connector.
  2. Check voltage between chassis ground and engine mount control solenoid harness connector terminal No. 3 (Black/Yellow wire). Battery voltage should be present. If battery voltage is present, go to next step. If battery voltage is not present, check circuit between solenoid harness connector terminal No. 3 and PCM fuse.
  3. Check voltage between engine mount solenoid harness connector terminals No. 3 (Black/Yellow wire) and No. 6 (Light Green wire). Battery voltage should be present. If battery voltage is present, go to next step. If battery voltage is not present, check circuit between solenoid harness connector terminal No. 6 and PCM. If circuit is okay, substitute a known-good PCM, and retest.
  4. Increase engine to speed to greater than 1000 RPM. Check voltage between solenoid harness connector terminals No. 3 (Black/Yellow wire) and No. 6 (Light Green wire). Battery voltage should not be present. If battery voltage is not present, check engine mount vacuum supply. See ENGINE MOUNT CONTROL SOLENOID VACUUM SUPPLY CHECK . If battery voltage is present, go to next step.
  5. Check for short to ground in Light Green wire between PCM and engine mount control solenoid harness connector. Repair as necessary. If circuit is okay, substitute a known-good PCM, and retest.
