HINT
Factors that affect the indicated vehicle speed include tire size, tire inflation, and tire wear. The speed indicated on the
speedometer has an allowable margin of error. This can be tested using a speedometer tester (calibrated chassis dynamometer).
For details about testing and the margin of error, see the reference chart See: Instrument Panel, Gauges and Warning
Indicators/Testing and Inspection/Symptom Related Diagnostic Procedures/Problem Symptoms Table.
OK:
The speed value output from the speed sensor displayed on the Techstream is the similar speed as indicated on the
speedometer.
NG -- REPLACE FRONT SPEED SENSOR
OK -- CHECK FOR INTERMITTENT PROBLEMS See: Accessories and Optional Equipment/Antitheft and Alarm
Systems/Diagrams/Diagnostic Aids/How To Troubleshoot ECU Controlled Systems/How To Proceed With Troubleshooting
