What is code P2201?
The P2201 code’s definition is “NOx sensor circuit range/performance (Bank 1).” It’s triggered when the powertrain control module (PCM) detects an issue with the nitrogen oxide sensors. The nitrogen oxide sensor measures the amount of nitrogen oxide expelled in the exhaust.
How do I fix code P2201?
What repairs can fix the P2201 code?
- Repairing or replacing damaged NOx sensor wiring.
- Repairing or replacing damaged NOx sensor connector.
- Replacing NOx sensor.
- Reprogramming or replacing the Engine Control Module.
What causes NOx sensor codes?
Your car’s computer will flash up these error codes if it receives a smaller voltage than expected from the NOx sensor signal wire. A broken or shorted wire, or an unwanted build-up of soot and debris, may cause this.
What does the code P2201 mean?
NOx sensor circuit range/performance
The P2201 code’s definition is “NOx sensor circuit range/performance (Bank 1).” It’s triggered when the powertrain control module (PCM) detects an issue with the nitrogen oxide sensors. The nitrogen oxide sensor measures the amount of nitrogen oxide expelled in the exhaust.
Do gasoline cars have NOx sensors?
Eventually, all stratified charge gasoline engines in the Volkswagen Group (1.4, 1.6 and 2.0 L) were equipped with NOx sensors. Other OEMs, including Daimler and BMW, also put large numbers of gasoline engines with charge stratification onto the roads.
How long do NOx sensors last?
However, on average, a Nox sensor can last between 50,000 to 60,000 miles. With proper maintenance, the sensor can last for more than that. In the same manner, it can fail long before covering 50k miles.
Is DPF the same as SCR?
Selective Catalytic Reduction is a separate component from the DPF in most applications, at least functionally if not physically. SCR is used to reduce Nitrogen (Di) oxide emissions from diesel engines which is again harmful. This is done by spraying Adblue (ammonia) over a material inside the SCR periodically.
