- Obtain access to ECT ECU, located near glove box. See Figure-Figure . Using ohmmeter, check for continuity between terminal SP2 of ECT ECU connector and body ground. See Figure.
- If continuity exists, replace ECT ECU. If continuity does not exist, check No. 2 speed sensor. See NO. 2 SPEED SENSOR under COMPONENT TESTING.
- Replace No. 2 speed sensor if defective. If No. 2 speed sensor is okay, check wiring between ECT ECU and No. 2 speed sensor. See appropriate wiring diagram in WIRING DIAGRAMS .
