Exhaust Heat Recirculation System Circuit: Procedure
WARNING: This page is about a different variant/trim than selected.
- CHECK HARNESS AND CONNECTOR (ENGINE COOLANT TEMPERATURE SENSOR - NO. 3 METER CIRCUIT PLATE (COMBINATION METER ASSEMBLY))
- Disconnect the engine coolant temperature sensor (for exhaust heat recirculation system) connector.
- Disconnect the No. 3 meter circuit plate (combination meter assembly) connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition G2-2 (TWS3) - L27-16 (TWS3) Always Below 1 Ω G2-1 (E2) - L27-9 (E2) Always Below 1 Ω G2-2 (TWS3) or L27-16 (TWS3) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (ENGINE COOLANT TEMPERATURE SENSOR - NO. 3 METER CIRCUIT PLATE (COMBINATION METER ASSEMBLY))
OK: Go to next step
- INSPECT ENGINE COOLANT TEMPERATURE SENSOR (FOR EXHAUST HEAT RECIRCULATION SYSTEM)
- Inspect the engine coolant temperature sensor (for exhaust heat recirculation system). Refer to INSPECTION .
NG → See step 3
OK → See step 4
- REPLACE ENGINE COOLANT TEMPERATURE SENSOR (FOR EXHAUST HEAT RECIRCULATION SYSTEM). Refer to REMOVAL
- REPLACE NO. 3 METER CIRCUIT PLATE (COMBINATION METER ASSEMBLY). Refer to DISASSEMBLY
