The fault code P2057 indicates a malfunction in the reductant injector circuit. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue varies between $75 and $150 per hour, depending on the auto repair shop.

Other factors that may influence the cost include the location of the repair shop, the type of vehicle, and the severity of the issue.

It is important to address this fault code promptly to avoid further damage to the vehicle and to ensure optimal performance.

The P2057 code indicates a problem with the Reductant Injection Valve Circuit Low Bank 2 U. The Reductant Dosing Valve is responsible for metering and atomizing the reductant liquid before it is mixed with the exhaust gas.

The valve’s cooling body 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 P2057 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P2057 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.
