- Mass air flow > 22.05 lb/h
- then > 30 Second(s) Idle speed
Possible fault causes
- Loose contact or corrosion on connectors or lines
- Short circuit to B+/ground or open circuit in the line
- Oxygen sensor behind catalytic converter Bank 1 Faulty
P0140
P0140
Diagnosis information - Control unit DME (DFI)
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.
INFORMATION
- Do not interchange the oxygen sensor in front of the catalytic converter with the sensor behind the catalytic converter as this will result in
implausible fault entries.
- The plugs themselves are coded and cannot be interchanged.
Diagnostic conditions
- Driving > 2 Minute(s), at:
- Engine at operating temperature
- Mass air flow > 22.05 lb/h
- then > 30 Second(s) Idle speed
Possible fault causes
- Loose contact or corrosion on connectors or lines
- Short circuit to B+/ground or open circuit in the line
- Oxygen sensor behind catalytic converter Bank 1 Faulty
