Vehicle Speed Pulse Sensor: Testing and Inspection
Vehicle Speed Signal Circuit Troubleshooting
Before testing:
-
Check to see if diagnostic trouble code P0720 (9) is indicated. If it is,troubleshoot the DTC.
-
Inspect the No.9 (10 A) fuse in the driver's under-dash fuse/relay box.
-
Check for continuity between the B16 terminal and body ground (G503).
1. Raise the vehicle, and make sure it is securely supported.
2. Disconnect the connector B (22P) from the gauge assembly.
3. Connect the B2 terminal to the positive probe of a voltmeter, and connect the negative probe to body ground. To prevent damage to the gauge
assembly, lay the gauge assembly on a shop rag.
4. Put the vehicle in neutral with the ignition switch ON (II).
5. Slowly rotate (over 3 mph (2 km/h)) one wheel with the other wheel blocked
Does voltage pulse from 0 to approx. 5 V or more?
YES - Replace the gauge assembly.
NO - Go to step 6.
6. Connect the No.9 terminal of the PCM connector A (32P) (except '01 model) or the No.26 terminal of the PCM connector E (31 P) ('01 model) to
the positive probe of a voltmeter, and connect the negative probe to body ground.
7. Put the vehicle in neutral with the ignition switch ON (II).
8. Slowly rotate (over 3 mph (2 km/h)) one wheel with the other wheel blocked
