What is P2200 : Engine Error code Causes Explained
The P2200 engine trouble number indicates a NOx sensor issue affecting emissions control. This guide explains the reasons, symptoms, and simple procedures to repair the problem for smoother engine running.
How to Identify a DTCs Number
The P2200 engine error code is related to the NOx (Nitrogen Oxide) sensor circuit. It typically indicates that there is an issue with the NOx sensor circuit in the engine management system.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
To identify the DTC (Diagnostic Trouble Code) number, you can use an OBD-II scanner. This device plugs into your car’s OBD-II port, which is typically located under the dashboard near the driver’s seat. Once connected, the scanner will read the error codes stored in the vehicle’s ECU and display the specific DTC number, such as P2200.
Causes of P2200 Error Code:
- Faulty Sensor.
The NOx sensor may be damaged, contaminated, or worn out. - Wiring or Connector Issues:
Corroded, damaged, or loose wiring can disrupt signals. - Exhaust System Leaks:
Leaks near the NOx sensor can cause inaccurate readings. - ECM Malfunction:
In rare cases, a faulty ECM may cause incorrect NOx sensor readings. - Defective SCR System:
A faulty SCR system may trigger this NOx emissions code.
Risk Level of P2200 Error Code:
A “High Risk Level” status occurs when this code points to a potentially serious malfunction in the emissions system that could lead to increased pollutants being emitted.
When facing a P2200 code along with by a “High Risk Level” warning, it’s essential to take immediate action.
Common Car Brands Affected by P2200 Code:
The P2200 code can affect various vehicles, it is most commonly associated with:
- Ford
- Volkswagen
- Audi
- Mercedes
- Chevrolet
- BMW
- Dodge

FAQ’s
What is the P2200 Engine Error Code?
The P2200 error code indicates a problem with the NOx (Nitrogen Oxide) sensor located in the exhaust system. It means that the sensor is providing an incorrect or faulty reading of NOx emissions, which affects the vehicle’s emissions control system.
What Causes the P2200 Engine Error Code?
The P2200 code can be caused by a malfunctioning NOx sensor, damaged wiring, faulty sensor connections, or exhaust leaks. It could also result from a defective engine control module (ECM) or an issue with the selective catalytic reduction (SCR) system.
Which Vehicles are Affected by the P2200 Code?
The P2200 code commonly affects diesel vehicles equipped with a NOx sensor and selective catalytic reduction systems. It is often found in models from Ford, Volkswagen, Audi, Mercedes, Chevrolet, BMW and Dodge.
