If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2202 fault code. This code indicates a problem with the Nitrogen Oxides (NOx) Sensor, which could be faulty or have a poor electrical connection. The sensor harness may also be open or shorted.

It’s important to address this issue promptly as it can lead to increased emissions and reduced fuel efficiency. The repair difficulty is moderate, and it should take about 1.0 hour to fix. To interpret the fault code, check the possible causes listed above and visually inspect the related wiring harness and connectors.

Repair Importance Level6.67 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level6.67 (Out of 10)

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2202 fault code.

Here are the symptoms to look out for:

  • The P2202 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, decreased fuel efficiency, and difficulty starting the engine.
  • Additionally, the vehicle may experience rough idling or stalling, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

P2202 fault code can be caused by a faulty NOx sensor, open or shorted harness, or poor electrical connection.

  • The automobile fault code P2202 can be caused by a faulty Nitrogen Oxides (NOx) sensor.
  • It can also be caused by an open or shorted Nitrogen Oxides Sensor harness.
  • Additionally, a poor electrical connection in the Nitrogen Oxides Sensor circuit can also trigger this fault code.

To fix the p2202 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code P2202, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This repair will take an estimated time of 1.0 hour.

The fault code P2202 indicates a problem with the NOx sensor circuit in the vehicle’s exhaust system. The estimated repair time for this fault code is 1.0 hour.

The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour. Other factors that may influence the cost include the location of the repair shop, the type of vehicle, and the severity of the issue.

The P2202 code is related to the NOx sensors in diesel engines. There are two NOx sensors, one upstream and one downstream of the selective catalytic reduction system.

The NOx sensors are connected to the control module via CAN and exchange information through it.

The NOx sensor contains a sensing cell, a pumping cell, and a heater.

The ECM sets a DTC when a serial data message is received from the NOx sensor module.

The P2202 code is set when the ECM software detects a fault in the NOx sensor circuitry or a performance fault in the NOx sensor for greater than 2 s.

What are the possible causes of the P2202 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P2202 fault code. This code is usually caused by a faulty Nitrogen Oxides (NOx) sensor, an open or shorted NOx sensor harness, or a poor electrical connection in the NOx sensor circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the P2202 fault code?

If you’re experiencing the P2202 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Nitrogen Oxides (NOx) Sensor, an open or shorted Nitrogen Oxides Sensor harness, or a poor electrical connection in the Nitrogen Oxides Sensor circuit. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.

What are the consequences of ignoring the P2202 fault code?

Ignoring the P2202 fault code, which indicates a faulty Nitrogen Oxides (NOx) sensor or related wiring issues, can lead to serious consequences such as reduced fuel efficiency, increased emissions, and potential damage to the engine. It is important to address the issue promptly by visually inspecting the wiring harness and connectors, checking for damaged components, and fixing any issues found.
