Observe all safety precautions: SAFETY PRECAUTIONS
View clean working conditions: CLEAN WORKING CONDITIONS
Use only gold-plated terminals when servicing any component with gold-plated electrical harness connector terminals.
For wiring diagrams, component locations, and connector views, Refer to the applicable wiring diagram.
Special tools and workshop equipment required
- Multimeter
- Electrical connector test lead set
Test conditions
- Battery voltage 12.5 V
- Fuse OK
- Engine MUST be at room temperature.
- Switch the ignition Off.
Test procedure
-- Perform a preliminary check to verify the customers complaint. Refer to PRELIMINARY CHECK
Start diagnosis
-- Engine MUST be at room temperature.
-- Disconnect the EGR Temperature Sensor -G98- -1- connector.
-- Using a multimeter, check the EGR Temperature Sensor -G98- terminals 1 to 2 for resistance.
Specified value: 6.96 K Ω (+/- 400 Ω at room temperature).
If the specified value was Not obtained:
-- Replace the EGR Temperature Sensor -G98-
-- Go to Final procedures
If the specified value was obtained:
-- Remove the Engine Control Module (ECM) -J623-. Refer to the Service Information.
-- Using a multimeter, check the EGR Temperature Sensor -G98- electrical harness connector terminals to the Engine Control Module (ECM) -J623- electrical harness connector T60 terminals for an open circuit according to the wiring diagram.
| EGR Temperature Sensor -G98- electrical harness connector terminals | Engine Control Module (ECM) -J623- electrical connector T60 terminals |
|---|---|
| 1 | 54 |
| 2 | 55 |
Specified value: 1.5 Ω Max.
If the specified value was Not obtained:
-- Check the wiring for an open, high resistance or short to ground.
-- Check the electrical harness connector for damage, corrosion, loose or broken terminals.
-- If necessary, repair the faulty wiring connection.
If there was no fault found in the wiring and the voltage was Not obtained:
-- Replace the Engine Control Module (ECM) -J623-. Refer to the Repair Information.
Final procedures
After the repair work, the following work steps must be performed in the following sequence:
- Check the DTC memory. Refer to DIAGNOSTIC MODE 03 - READ DTC MEMORY .
- If necessary, erase the DTC memory. Refer to DIAGNOSTIC MODE 04 - ERASE DTC MEMORY .
- If the DTC memory was erased, generate readiness code. Refer to READINESS CODE .
