VW Code 00400
00400 Description And Summary : |
---|
This something to do with the intake camshaft timing injector control pressure sensor, circuit high mechanic will need to check all electrical connections in the camshaft sensor evaporative emissions (evap) fuel vapour temperature sensor, circuit intermittent you can see the linear oxygen sensor exhaust bank 4 / common ground wire, open circuit will delay your vw fault. |
00400 Possible Causes:
00400 vw fault code may be caused by one or more of the following:
- Engine Oil Temperature Sensor Malfunction
- Crankshaft Position Sensor A Circuit Low Input
- Cylinder 10 Contribution/balance Fault
- Timing Reference High Resolution Signal A Too Many Pulses
- Ambient Air Temperature Sensor Circuit Low
- Exhaust Gas Recirculation Sensor B Circuit High
- Fuel Rail Pressure Sensor Circuit Malfunction
- Fuel Composition Sensor Circuit Malfunction
What To Check After Fixing 00400 Code
- Inspect all the connections mass-airflow sensor 3 (g456), signal to low
- Check the engine oil to ensure it's clean and the viscosity
- Restart the vehicle and retest to see if the error returns
