TROUBLE DIAGNOSIS OF TURBOCHARGER
Preliminary check:
●
Check that the engine oil level is between MIN and MAX of the dipstick. (When the engine oil amount is
more than MAX, the oil flows into the inlet duct through the blow-by gas passage, and the turbocharger is
misjudged failure.)
●
Ask the customer if he/she always runs the vehicle in idle engine speed to cool the oil down after driving.
●
Replace the 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 failure. Check
the other parts again.
A: Large possibility
B: Medium possibility
