NOTE: If the MIL is ON, troubleshoot the PGM-FI problem first.
  1. With the transmission in neutral, raise the vehicle on a lift, and make sure it is securely supported.
  2. Disconnect the VSS 3P connector (A):

  3. Turn the ignition switch to ON (II).
  4. Check for continuity between VSS 3P connector terminal No. 3 and body ground.

    Is there continuity? 

    YES  -Go to step 5.

    NO  -Repair an open or high resistance in the BRN/YEL wire between the VSS and G101.

  5. Measure the voltage between the VSS 3P connector terminal No. 1 and body ground.

    Is there about 5 V? 

    YES  -Go to step 6.

    NO  -Repair short or open in the YEL/BLU wire between the VSS and the ECM.

  6. Reconnect the VSS 3P connector.
  7. Slowly rotate the propeller shaft.
  8. Measure the voltage between gauge assembly connector C (20P) terminal No. 3 and body ground ('00-03 models), or between gauge assembly connector B (30P) terminal No. 7 and body ground ('04-05 models).

    Does the voltage pulse from 0 to about 5 V? 

    YES  -Check for poor connections or loose terminals at the VSS and the gauge assembly. If needed, replace the VSS (see VSS REPLACEMENT ) and/or the printed circuit board in the gauge assembly.

    NO  -Go to step 9.

  9. Turn the ignition switch to LOCK (0).
  10. Disconnect the 3P connector from the vehicle speed sensor (VSS).
  11. Turn the ignition switch to ON (II).
  12. Measure the voltage between the VSS 3P connector terminal No. 2 and body ground.

    Is there about 5 V? 

    YES  -Replace the VSS.

    NO  -Repair a short to ground or an open in the BLU/WHT wire.
