Description: Exhaust Gas Recirculation Cooler Performance Monitor
Troubleshooting:
DESCRIPTION:
Exhaust Gas Recirculation (EGR) Cooler performance monitor.
MONITORED PARAMETER:
Intake manifold temperature sensor.
TYPICAL ENABLING CONDITIONS:
Engine running greater than 5 minutes, EGR mass flow greater than .08, intake manifold
temperature less than 125°C (257°F), engine speed 1200 to 2500 rpm, engine torque 500 to
2500 N·m (368.6 to 1844 lb·ft), coolant temperature greater than 65°C (149°F), ambient
temperature less than 45°C (113°F) ambient, coolant temperature greater than 65°C (149°F),
ambient temperature greater than -8°C (17.6°F) ambient, barometric pressure greater than 755
mbar (10.95 psi).
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Always enabled
TYPCIAL DURATION:
30 seconds
DASH LAMPS:
1. MIL
2. CEL
ENGINE REACTION:
None
VERIFICATION:
When ambient temperature less than 45°C (113°F), start engine, warm up so coolant
temperature greater than 65°C (149°F), ambient barometric pressure greater than 755 mbar
(10.95 psi).
POSSIBLE CAUSES:
1. Bent pins.
2. Spread pins.
3. Corroded pins.
4. Faulty intake manifold temperature sensor harness connector.
5. Faulty intake manifold temperature sensor.
6. External leakage
7. Faulty EGR cooler.
