Possible causes |
Action |
P017100 |
System Too Lean (Bank 1) |
- Air intake leak between MAF sensor and cylinder head
- MAF sensor fault (low intake air flow)
- Low fuel pressure
- Fuel filter/system restriction
- Fuel pump module fault
- Fuel injector restriction
- Exhaust leak (before catalyst)
- Evaporative emission system fault
|
Check the intake air system for leaks. Check the MAF sensor
condition and circuits. Check the fuel pressure. Check the fuel filter for
a blockage/restriction. Check the fuel system for leaks/damage. Check the
fuel pump module operation. Check the fuel injectors. Check the exhaust
system for leaks, etc. Refer to the relevant section of the workshop
manual. Check for evaporative emission DTCs. |
P017200 |
System Too Rich (Bank 1) |
- Restricted air filter
- High fuel pressure
- Leaking fuel injector(s)
- Oil contaminated with fuel (too many cold starts with vehicle
subsequently not getting hot enough for long enough)
- MAF sensor fault
- Evaporative emission system fault
|
Check the intake air system for restrictions. Check the fuel
system for leaks and check the fuel pressure. Check the fuel injectors.
Check for fuel system DTCs. Check the oil for contamination/grade/quality.
Refer to the relevant section of the workshop manual. Check for MAF sensor
and evaporative emission DTCs. |

|
Check the intake air system for leaks, etc. Check the fuel
system for restrictions, DTCs, etc. Check the exhaust system for leaks,
etc. Refer to the relevant section of the workshop manual. Check for
evaporative emission DTCS. |
