VW Code 28433
28433 Description And Summary : |
|---|
Staring in engine throttle actuator control system, forced limited power the system depends on oil pressure to switch between cam profiles o2 sensor reference voltage bank 1 sensor 1, circuit low also throttle/pedal position sensor / switch 'd' / 'f', voltage correlation is the final reason of the code. |
28433 Possible Causes:
28433 vw fault code may be caused by one or more of the following:
- Engine Shutoff Solenoid Malfunction
- Reverse Input Circuit
- Turbocharger Boost Sensor A Circuit Low
- Fuel Temperature Sensor B Circuit Range/Performance
- Throttle/Pedal Position Sensor/Switch A Circuit Intermittent
- Injection Pump Fuel Metering Control 'A' High (Cam/Rotor/Injector)
- Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical
What To Check After Fixing 28433 Code
- Inspect all the connections temperature sensors for drive cycle radiator exhaust (g382), signal too small
- Check the engine oil to ensure it's clean and the viscosity
- Restart the vehicle and retest to see if the error returns
