INSPECTION PROCEDURE
Trouble Diagnosis of Turbocharger
Check items before trouble diagnosis
1. Check that the engine oil level is between L (Low level) and H (High level) of the oil level gauge. [When the engine oil amount is more then H (High level), the engine oil flows into the inlet duct through the blowby gas passage, and the turbocharger is misjudged failure.]
2. Ask the customer if he/she always runs the vehicle in idle engine speed to cool the engine oil down after driving.
- Replace the exhaust manifold and turbocharger assembly when any malfunction is found after unit inspections specified in the table below.
- If no malfunction is found after the unit inspections, judge that the turbocharger body has no non-standard conditions. Check the other parts again.
