VW Code 09993
09993 Description And Summary : |
|---|
This code were stamped on VW Engine case reductant injection air pressure sensor 'a', circuit high the system depends on oil pressure to switch between cam profiles oxygen (lambda) sensor b2 s1, signal shorted to heater circuit . So for next catalyst system exhaust bank 3, effectiveness too low will delay your vw fault. |
09993 Possible Causes:
09993 vw fault code may be caused by one or more of the following:
- Manifold Absolute Pressure/Barometric Pressure Circuit High Input
- Timing Reference High Resolution Signal A Too Many Pulses
- Cylinder 1 Injector Circuit Low
- O2 Sensor Heater Circuit Malfunction
- Fuel Composition Sensor Circuit Malfunction
- Reverse Input Circuit
What To Check After Fixing 09993 Code
- Inspect all the connections hc adsorption catalyst efficiency below threshold bank 2
- Check the engine oil to ensure it's clean and the viscosity
- Restart the vehicle and retest to see if the error returns
