DTC
Description
Possible Cause
Action
MAF sensor fault
- Low intake flow
Exhaust leak, before catalytic
converter
P017500 System too rich (bank 2)
Restricted air filter
Oil contaminated with fuel
- Too many cold starts with
vehicle subsequently not
getting hot enough for long
enough
Leaking fuel injectors
MAF sensor fault
- High intake flow
Leaking evaporative emission
system purge valve
Check the condition of the air cleaner
element:
REFER to:
Air Cleaner
(303-12B Intake Air
Distribution and Filtering - TD4 2.2L Diesel,
Removal and Installation).
Check engine the oil condition. Check for
leaking injectors. Check for MAF sensor,
injector and evaporative emission system
DTCs.
