Emission Control System -- On-Vehicle Inspection |
- УКАЗАНИЕ:
- In a malfunction that the EGR system is always operating, black or white smoke may be emitted from the exhaust pipe.
| 1. CHECK SEATING OF EGR VALVE |
Start the engine, then check that it starts and runs at idle.
| 2. CHECK HOT ENGINE CONDITION |
Connect the intelligent tester to the DLC3.
 |
Start the engine, then run it at idle.
Turn the intelligent tester on.
Select "Powertrain / ENGINE / Active Test Control the EGR Position" in Data List.
Warm up the engine.
The coolant temperature should be between 75°C (167°F) and 90°C (194°F).
Check the EGR position and measure the MAF reading.
- Standard value (EGR position 1 to 100%):
Engine Condition EGR Position Active Test MAF Idling 1 to 100% Active test not performed 2.8 to 5.4 g/sec.
- Standard value (EGR position 0%):
Engine Condition EGR Position Active Test MAF Idling 0% Active test not performed 5.6 to 9.9 g/s
- УКАЗАНИЕ:
- If the MAF reading is out of the standard range in either conditions "Active test performed" or "Active test not performed", replace the EGR valve.
- If the MAF reading is out of the standard range in both conditions "Active test performed" and "Active test not performed", check the intake air flow meter.
| 3. VISUALLY INSPECT HOSES, CONNECTORS AND GASKETS |
Check for cracks, leaks or damage.
Check the engine assembly to see if the portions indicated by the arrows have cracks, leaks or damage.
- ПРИМЕЧАНИЕ:
- Detachment or other problems with the engine oil dipstick, filler cap, PCV hose and other components may cause the engine to run improperly.
- Air suction caused by disconnections, looseness or cracks in the parts of the air induction system between the throttle body and cylinder head will cause engine failure or engine malfunctions.
