Description
Possible Causes
Action
P011300 Intake air temperature
sensor 1 circuit high
Intake air temperature (IAT)
sensor 1 circuit: short circuit
to power
Intake air temperature (IAT)
sensor 1 circuit: open circuit
Intake air temperature (IAT)
sensor failure
Check the IAT sensor and circuits (the IAT sensor
is incorporated into the MAF sensor). Refer to the
electrical guides. Install a new sensor as
required.
REFER to:
Mass Air Flow (MAF) Sensor

Removal and Installation).
P011400 Intake air temperature
sensor 1 circuit
intermittent/erratic
Intake air temperature (IAT)
sensor 1 circuit: high
resistance
Intake air temperature (IAT)
sensor failure
Check the IAT sensor and circuits (the IAT sensor
is incorporated into the MAF sensor). Refer to the
electrical guides. Install a new sensor as
required.

P017100 System too lean (bank 1)
Intake air leak
- Between MAF sensor and
cylinder head
Fuel system restriction
MAF sensor fault
- Low intake flow
Exhaust leak, before catalytic
converter
Check for intake air leaks. Check for low fuel
pressure and MAF sensor DTCs. Rectify as
necessary. Check for exhaust leaks before the
catalytic converter
P017200 System too rich (bank 1)
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
(303-12A Intake Air
Distribution and Filtering - I6 3.2L Petrol,
Removal and Installation).
Check engine the oil condition. Check for leaking
injectors. Check for MAF sensor, injector and
evaporative emission system DTCs.
P017400 System too lean (bank 2)
Intake air leak
- Between MAF sensor and
cylinder head
Fuel system restriction
MAF sensor fault
- Low intake flow
Exhaust leak, before catalytic
converter
Check for intake air leaks. Check for low fuel
pressure and MAF sensor DTCs. Rectify as
necessary. Check for exhaust leaks before the
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
(303-12A Intake Air
Distribution and Filtering - I6 3.2L Petrol,
Removal and Installation).
Check engine the oil condition. Check for leaking
injectors. Check for MAF sensor, injector and
evaporative emission system DTCs.
P050600 Idle air control system
RPM lower than expected
Intake air restriction
Restricted/Contaminated
injector/fuel system
Accessory drive overload
(defective/seized component)
Variable intake system (VIS)
fault
Throttle body fault
Check the intake air system, air cleaner, etc.
Check the fuel system for
restriction/contamination. Check the accessory
drive driven components for excessive resistance
to turning/seizure. Rectify as necessary. Check
for DTCs indicating a VIS or throttle body fault.
P050700 Idle air control system
RPM higher than
expected
Intake air leakage
Variable intake system (VIS)
fault
Throttle body fault
Check the intake air system for leakage. Rectify
as necessary. Check for DTCs indicating a VIS or
throttle body fault.
P050B00 Cold start ignition timing
performance
Blocked intake system
Sticking/slow throttle
Poor engine condition
Check the intake air system, including the air
cleaner element. Carry out a complete vehicle
read for related DTCs. Rectify as necessary.
P061A00 Internal control module
torque performance
Air leakage in the intake
system after the MAF sensor
and throttle body
Throttle body fault
Mass air flow (MAF) sensor
fault
Engine coolant temperature
(ECT) sensor fault
Flywheel sensor fault
Retrieve the flight recorder data and customer
statement for return to engineering for analysis.
Check the intake system for leakage. Check for
DTCs indicating a throttle body, sensor or VVT
fault. Rectify as necessary. Refer to the warranty
policy and procedures manual if a module is
suspect.
