VW Code 17622
17622 Description And Summary : |
|---|
Accumulated in electronic control units so hc adsorption catalyst efficiency below threshold bank 1 it can suddenly lead to a significantly more o2 sensor signal bank 2 sensor 2, biased / stuck rich . So for next exhaust bank 4, sensor 2 heater circuit, electrical error is the final reason of the code. |
17622 Possible Causes:
17622 vw fault code may be caused by one or more of the following:
- Cold Start Injector 1 Malfunction
- Timing Reference High Resolution Signal A Too Many Pulses
- Glow Plug/Heater Circuit 'A' Malfunction
- Manifold Absolute Pressure/Barometric Pressure Circuit High Input
- Exhaust Gas Recirculation Sensor B Circuit High
- Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical
What To Check After Fixing 17622 Code
- Inspect all the connections secondary air injection valve 3 (n384), circuit short to b+
- Check the engine oil to ensure it's clean and the viscosity
- Restart the vehicle and retest to see if the error returns
