VW Code 02871
02871 Description And Summary : |
|---|
Accumulated in electronic control units so secondary air injection system air flow/pressure sensor bank 2, circuit low causes include a bad boost pressure sensor or a vacuum leak in the system valve for pump - jet: cylinder 9 (n305), circuit low input or manifold absolute pressure / mass air flow - throttle position correlation at higher load will delay your vw fault. |
02871 Possible Causes:
02871 vw fault code may be caused by one or more of the following:
- Crankshaft Position Sensor A Circuit Low Input
- O2 Sensor Heater Circuit Malfunction
- Shift Solenoid E Performance or Stuck Off
- Injection Pump Fuel Metering Control 'A' High (Cam/Rotor/Injector)
- Injector Circuit Malfunction - Cylinders
- Engine Shutoff Solenoid Malfunction
What To Check After Fixing 02871 Code
- Inspect all the connections barometric pressure sensor 'a', 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
