If you see the engine light on or the service engine soon warning light, it could be due to the P22A7 fault code.
This code indicates a problem with the Nitrogen Oxides (NOx) Sensor 2, which could be faulty or have a poor electrical connection. It could also be due to an open or shorted harness.
The importance of repairing this issue lies in the fact that it affects the vehicle’s emissions and can lead to a failed emissions test. The repair difficulty is moderate, with a repair time of 1.0.
To fix the issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

P22A7: Affordable Fix For Complex Automobile Fault Code
The fault code P22A7 indicates an issue with the NOx sensor circuit in the engine. 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 most shops to charge between $75 and $150 per hour. Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.
P22A7: Unleashing The Mystery Of Your Car’s Fuel System
The P22A7 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 varies the amount of diesel exhaust fluid added by varying the reductant injector duty cycle in response to changes in engine exhaust NOx levels. The DTC will be set if the ECM software detects a fault in the NOx sensor circuitry or a performance fault in the NOx sensor for greater than 2 s.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P22a7 fault code. This code is caused by a faulty Nitrogen Oxides (NOx) Sensor 2, an open or shorted Nitrogen Oxides Sensor 2 harness, or a poor electrical connection in the Nitrogen Oxides Sensor 2 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.
If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a faulty Nitrogen Oxides (NOx) Sensor 2, it’s important to visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This could be caused by an open or shorted Nitrogen Oxides Sensor 2 harness or a poor electrical connection in the Nitrogen Oxides Sensor 2 circuit. Check the “Possible Causes” listed above for more information.
If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection, follow these steps. First, visually inspect the related wiring harness and connectors. Then, check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Finally, check the “Possible Causes” listed above and fix the issue accordingly to resolve the Engine Light ON (or Service Engine Soon Warning Light) caused by a faulty Nitrogen Oxides (NOx) Sensor 2, Nitrogen Oxides Sensor 2 harness being open or shorted, or Nitrogen Oxides Sensor 2 circuit poor electrical connection.
Wrap Up
If you see the Engine Light ON or Service Engine Soon Warning Light with the fault code p22a7, it could be due to a faulty Nitrogen Oxides (NOx) Sensor 2, open or shorted harness, or poor electrical connection. To fix it, visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
