Electronic Speed Sensor Module Test

  1. Number harness terminals from 1 to 6 (or 8), starting with terminal No. 1 nearest the locator key. With ignition on, connect negative voltmeter lead to ground and touch positive lead, in turn, to terminals No. 1, 4, and 6. Battery voltage should be indicated at terminals No. 1 and 4. Terminal No. 6 should be 6-8 volts.
  2. If voltage is less than 6 volts, service harness as necessary. If all tests are satisfactory, and problem still remains, replace electronic speed sensor module.
