C0111 Bmw 320i Diagnostic Trouble Code
C0111 Bmw 320i code definition:
C0111 is a kind of OBD-II Diagnostic C-Chassis Diagnostic Trouble Code for Bmw 320i.
C0111 Bmw 320i is described as Oxygen Sensor Circuit No Activity Detected (Bank 1, Sensor 1). This means there's a problem in the front oxygen sensor on Bank 1, as the O2 sensor is inactive. As you drive and when specific conditions are slowly met, the vapors will gradually purge from the charcoal canister and will get burned within your engine.
Symptoms
Symptoms of a C0111 Bmw 320i diagnostic trouble code may include:
- Lack of power
- Faulty O2 Sensor
- Poor acceleration
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
|
Possible Causes :
- Defective ECU strategies or components will prevent proper regeneration
- The Mass Airflow sensor is a hot wire that senses the volume of air entering the intake manifold. The computer uses this information to control fuel mixture.
- Rough running engine due to misfiring plugs. Many engines have misfire codes to indicate the cylinder effected, such as P0307 for number 7.

Common Misdiagnoses
- IC Circuit High Voltage Problem
- Control Module Throttle Actuator Position Performance Problem
- Air Conditioning (A/C) Clutch Feedback Circuit High Voltage Problem
- Cruise Vehicle Speed/Set Speed Difference Too High Problem
- PCM Stack Overrun Problem
Repair Processes :
Look for missing ground strap or a rusty ground where the fuel tank is grounded to the frame. Check for damage to the wiring harness connector.
It should be pretty close to battery voltage (12 volts). If not, then this is the circuit that has the problem.
Oxygen sensors signal the engine management computer the amount of oxygen present in the exhaust, which is used in determining and controlling the fuel ratio.
