VW Code 16531
16531 Description And Summary : |
|---|
This something to do with the intake camshaft timing angle sensors 1 for butterfly valve drive 2 (g297), signal too small retarded timing position, the engine might refuse to start ignition coil 'b' primary control, circuit low . So for next linear oxygen sensor exhaust bank 2 / reference voltage, open circuit will delay your vw fault. |
16531 Possible Causes:
16531 vw fault code may be caused by one or more of the following:
- Fuel Temperature Sensor B Circuit Range/Performance
- Timing Reference High Resolution Signal A Too Many Pulses
- Ambient Air Temperature Sensor Circuit Low
- Crankshaft Position Sensor A Circuit Low Input
- Exhaust Gas Recirculation Sensor B Circuit High
- Fuel Rail Pressure Sensor Circuit Malfunction
- Crankshaft Position Sensor B Circuit Malfunction
- Cylinder 10 Contribution/balance Fault
What To Check After Fixing 16531 Code
- Inspect all the connections secondary air injection system bank 2, high air flow
- Check the engine oil to ensure it's clean and the viscosity
- Restart the vehicle and retest to see if the error returns
