0-36.2 P0171, P0174
Oxygen Sensing Adaptation, Idle Range, Bank 1 & Bank 2 –
Above Limit
Possible fault cause
♦ Incorrect signal from MAF sensor
♦ Intake air system leaking
♦ Fuel pressure too low
♦ Volume supply of fuel pump too low
♦ Fuel injectors fouled
♦ PCV valve leaks
♦ Cap of oil filler neck not closed correctly or seal is damaged
P0507
32 Idle air control at stop - above limit
Possible fault cause
♦ Throttle is jammed
♦ Leaks in intake air system
I would first check for leaks to the system (check hoses and connections).
