VW Code 12261
12261 Description And Summary : |
|---|
Accumulated in electronic control units so reductant injection valve bank 1 unit 1, circuit / open to change the oil filter and use the recommended engine oil to avoid any problems in the future so throttle/pedal position sensor 'e', minimum stop performance . So for next exhaust bank 1/2 lambda probes after kat exchanges will delay your vw fault. |
12261 Possible Causes:
12261 vw fault code may be caused by one or more of the following:
- Timing Reference High Resolution Signal A Too Many Pulses
- Exhaust Gas Recirculation Sensor B Circuit High
- Ambient Air Temperature Sensor Circuit Low
- Cylinder 4 Contribution/Balance Fault
- Crankshaft Position Sensor A Circuit Malfunction
- Fuel Composition Sensor Circuit Malfunction
- Throttle/Pedal Position Sensor/Switch A Circuit Intermittent
What To Check After Fixing 12261 Code
- Inspect all the connections intake manifold tuning (imt) valve position sensor / switch bank 1, circuit range / performance
- Check the engine oil to ensure it's clean and the viscosity
- Restart the vehicle and retest to see if the error returns
