- Deviation Actual value - Nominal value > 10锟斤拷 Intake camshaft
or
- Adjustment Intake camshaft slow
P12A1
P12A1
Diagnosis information - Control unit DME (DFI)
Fuel high-pressure sensor implausible
INFORMATION
- Faults in the fuel high-pressure injection system are often caused by defects in the pre-delivery system (fuel low pressure).
- Therefore, if there are problems in the fuel high-pressure injection area, the predelivery circuit must be checked first.
Diagnostic conditions
- Period since engine was started > 250 Second(s)
- Engine temperature -10 ... +100 锟斤拷C (锟斤拷F)
- Engine speed 450 ... 4000 1/min
- Lambda control Active
Possible fault causes
- Pre-delivery quantity or pressure in fuel low-pressure circuit too low
- Fuel high-pressure system leaks
- Fuel high-pressure sensor Faulty
- Fuel high-pressure pump Faulty
Fault setting condition(s)
- long-term deviation Fuel high-pressure actual value - Nominal value (The setpoint is calculated using several values. , e.g. Lambda control,
Quantity control valve,...)

Oxygen sensor behind catalytic converter Bank 1
NOTE
Separated plug connection = open reference-air duct.
Damage to oxygen sensor.
- DO NOT use spray, grease, fluid or similar products on the oxygen sensor plug connections.
