Here are the symptoms to look out for:

  • The P2052 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 a decrease in engine performance, reduced fuel efficiency, and rough idling.
  • Additionally, the vehicle may experience difficulty starting, stalling, or misfiring.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

P2052 fault code can be caused by a faulty valve, open or shorted harness, or poor electrical connection.

  • The automobile fault code p2052 can be caused by a faulty Reductant Injection Valve.
  • It can also be caused by an open or shorted Reductant Injection Valve harness.
  • Additionally, a poor electrical connection in the Reductant Injection Valve circuit can also trigger this fault code.

Below are some possible fixes for the automobile fault code p2052, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2052, 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 fix will take an estimated repair time of 1.0 hour.

The fault code P2052 indicates a malfunction in the Reductant Injector Circuit. The estimated repair time for this issue 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 location of the shop, the type of vehicle, and the severity of the issue. It is important to address this issue promptly to avoid further damage to the vehicle and potential safety hazards.

The P2052 code refers to a fault in the Reductant Injection Valve Circuit High Bank 2 Unit 1. The Reductant Dosing Valve is responsible for metering and atomizing the reductant liquid before it is mixed with the exhaust gas. The valve’s normal operating frequency is between 3 Hz and .3 Hz, and it contains heat sink fins to keep the injector and reductant below the boiling point.

If the sensed temperature is nearing the maximum temperature threshold, reductant spray will be increased in quantity to actively cool the valve.

What are the possible causes of the P2052 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P2052 fault code. This code is caused by a faulty reductant injection valve, an open or shorted valve harness, or a poor electrical connection in the valve 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 pins.

How can I visually inspect the wiring harness and connectors related to the Reductant Injection Valve?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Reductant Injection Valve or a poor electrical connection. 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. This will help you identify if the Reductant Injection Valve harness is open or shorted, and allow you to take the necessary steps to resolve the issue.

What should I do if I find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection, it could be the cause of the engine light being ON. To fix this issue, check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
