DH94 - Monitor TP Circuit Under Simulated Road Shock
Sensor Wiring Schematic:
- Enter Continuous Monitor Diagnostic Test Mode (DTM). Continuous Monitor Diagnostic Test Mode (Wiggle Test)
- Connect Analog Volt/Ohm Meter (VOM) or STAR LED to Self Test Output (STO).
- Observe VOM or STAR LED for indication of a fault while performing the following:
- Move throttle slowly to Wide Open Throttle (WOT) position.
- Release throttle slowly to closed position.
- Lightly tap on Throttle Position (TP) sensor (simulate road shock)
- Wiggle TP harness connector
- Is a fault indicated?
Yes -- Key "OFF". Inspect connectors. If connectors and terminals are good, replace TP sensor. Clear continuous memory. Clearing Diagnostic Trouble Codes
Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)
No -- Go to DH95. DH95 - Check EEC Vehicle Harness
