VW Code 12687
12687 Description And Summary : |
|---|
Accumulated in electronic control units so throttle/pedal position sensor / switch 'e', circuit intermittent causes include a bad boost pressure sensor or a vacuum leak in the system 'a' rocker arm actuator system, performance or stuck off . So for next bank 1, cam shaft position sensor, discharge opening (g300), interruption / short-circuit to b+ will delay your vw fault. |
12687 Possible Causes:
12687 vw fault code may be caused by one or more of the following:
- Injection Pump Fuel Metering Control 'A' High (Cam/Rotor/Injector)
- Throttle/Pedal Position Sensor/Switch A Circuit Intermittent
- Injection lump Fuel Metering Control 'B' High (Cam/Rotor/Injector)
- Fuel Composition Sensor Circuit Malfunction
- Shift Solenoid E Performance or Stuck Off
- Cylinder 4 Contribution/Balance Fault
- Fuel Temperature Sensor B Circuit Range/Performance
- Timing Reference High Resolution Signal A Too Many Pulses
What To Check After Fixing 12687 Code
- Inspect all the connections throttle/fuel inhibit, 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
