-
Connect multimeter to terminals 2 and 1 (shielding) and to terminals 3 and 1 (shielding) for resistance measurement.
-
Specified value: each infinity Ohm (no continuity)
If specified value is not obtained:
-
Replace Engine Speed (RPM) sensor -item 23-.
If specified value is obtained:
Checking wire connections
-
Connect test box to wiring harness of Engine Control Module (ECM); ECM is not connected. See: Testing and Inspection/Reading and Clearing

If necessary, repair wire connection.
If no malfunctions are detected:
-
Replace Engine Control Module (ECM).
Final procedures
After repair work, the following work steps must be performed in the mentioned sequence:
1
-
Check DTC memory, "Mode 3: Check DTC memory". See: Testing and Inspection/Scan Tool Testing and Procedures/Scan Tool Testing/With
Generic Scan Tool/Diagnostic Mode 3: Check DTC Memory
2
-
If necessary, erase DTC memory, "Mode 4: Reset/erase diagnostic data". See: Testing and Inspection/Scan Tool Testing and Procedures/Scan
