Where is NOx sensor located?

The NOx sensor is part of the NOx reduction aftertreatment system used in diesel vehicles with urea based SCR systems. The sensor located upstream of the SCR catalyst directly measures the engine-out NOx gas concentration, which helps determine the optimum amount of urea injection.

What causes NOx sensor codes?

What causes the P2202 code?

  • The engine control module (ECM) monitors the NOx sensor bank 1 signal wire and the output voltage, and the ECM is expecting lower than specified voltage for the conditions.
  • The NOx sensor is shorted internally or the wiring is shorted causing the low voltage.

When to use the p2201 NoX sensor code?

The P2201 code is set when the ECM detects an out of range electrical condition within the bank #1 NOx sensor or circuit. Note: On engines with more than one bank of cylinders (e.g. V6, V8), bank 1 is the side of the engine that contains the #1 cylinder.

Where is the NoX sensor located in bank 1?

Note: On engines with more than one bank of cylinders (e.g. V6, V8), bank 1 is the side of the engine that contains the #1 cylinder. Therefore, the NOx sensor is located in the exhaust of that bank.

What causes the p2201 OBD-II trouble code?

What causes the P2201 code? 1 NOx sensor wires that are broken or shorted 2 NOx sensor connector that is corroded or broken 3 NOx sensor connector pins that are bent 4 Faulty NOx sensor. 5 Engine Control Module that needs to be reprogrammed or replaced
