The cost of fixing the fault code depends on the repair time. Most auto repair shops charge between $75 and $150 per hour. Therefore, the fixing cost of P2053 can range from $75 to $150.

The P2053 fault code indicates an issue with the Reductant Injection Valve CircuitOpen Bank 1 U. The Reductant Dosing Valve is responsible for metering and atomizing the reductant liquid before it mixes with the exhaust gas. The valve’s normal operating frequency ranges from 3 Hz to .3 Hz, and its cooling body contains heat sink fins to prevent boiling.

If the valve’s temperature approaches the maximum threshold, the reductant spray will increase to actively cool the valve.

What are the possible causes of the P2053 automobile fault code?

If your engine light is on and you’re seeing the P2053 fault code, it could be due to a faulty Reductant Injection Valve, an open or shorted Reductant Injection Valve harness, or a poor electrical connection in the Reductant Injection Valve circuit. 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.

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.
