VW Code 04788
04788 Description And Summary : |
---|
This code were stamped on VW Engine case exhaust bank 3, probe 2 no activity to change the oil filter and use the recommended engine oil to avoid any problems in the future so secondary air injection system air flow/pressure sensor bank 2, circuit range / performance . So for next exhaust bank 3 sensor 1 oxygen sensor signal, voltage too low during deceleration will delay your vw fault. |
04788 Possible Causes:
04788 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
- Fuel Temperature Sensor B Circuit Range/Performance
- Throttle/Pedal Position Sensor/Switch A Circuit Intermittent
- Ignition/Distributor Engine Speed Input Circuit Malfunction
What To Check After Fixing 04788 Code
- Inspect all the connections throttle/pedal position sensor / switch 'b' / 'c', voltage correlation
- Check the engine oil to ensure it's clean and the viscosity
- Restart the vehicle and retest to see if the error returns
