Ford NOx sensors are a type of sensor used in Ford vehicles to measure the levels of nitrogen oxide (NOx) emissions in the vehicle’s exhaust system. These sensors play an important role in monitoring the vehicle’s emissions and ensuring that they meet government-mandated standards.

The Ford NOx sensor works by measuring the levels of NOx in the vehicle’s exhaust gases. It does this by using a chemical reaction between the NOx and a sensor element in the sensor. The sensor then sends a signal to the vehicle’s engine control module (ECM) indicating the level of NOx in the exhaust gases.

OE number list:
The OE (original equipment) number for Ford NOx sensors can vary depending on the specific make and model of the vehicle. Here are some common OE numbers for Ford NOx sensors:

  • 2382101
  • HC3A-5L248-CB
  • JK21-5L248-AG
  • JK21-5L248-AF
  • JK21-5L248-AC
  • LK21-5E145-AA1

It’s important to note that these OE numbers may not be applicable to all Ford vehicles, and it’s always best to consult the vehicle’s owner’s manual or a trusted mechanic to ensure that the correct part is being used.

Error code introduction:
If there is a problem with the Ford NOx sensor, it may trigger an error code in the vehicle’s ECM. Here are some common error codes related to Ford NOx sensors:

P2201: This code indicates that there is a problem with the NOx sensor circuit or signal.
P2202: This code indicates that the NOx sensor circuit is low.
P2203: This code indicates that the NOx sensor circuit is high.
If any of these error codes are detected, it’s important to have the vehicle inspected by a qualified mechanic to determine the root cause of the problem and make any necessary repairs.
