VW Code 09140
09140 Description And Summary : |
|---|
Accumulated in electronic control units so direct ozone reduction catalyst deterioration sensor, circuit high causes include a bad boost pressure sensor or a vacuum leak in the system manifold absolute pressure / mass air flow - throttle position correlation at idle or exhaust bank 4 sensor 1 oxygen sensor signal, voltage too low during deceleration is the final reason of the code. |
09140 Possible Causes:
09140 vw fault code may be caused by one or more of the following:
- Ambient Air Temperature Sensor Circuit Low
- Ignition/Distributor Engine Speed Input Circuit Malfunction
- Crankshaft Position Sensor B Circuit Malfunction
- Clutch Position Sensor Circuit Malfunction
- Cylinder 4 Contribution/Balance Fault
- Fuel Rail Pressure Sensor Circuit Malfunction
- Cold Start Injector 1 Malfunction
What To Check After Fixing 09140 Code
- Inspect all the connections pressure sensor for brake boost (g294), implausible signal
- Check the engine oil to ensure it's clean and the viscosity
