The automobile fault code P2ADB has an estimated repair time of 1.0 hour.

The cost of fixing this code can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour. These factors can influence the overall cost of diagnosing and fixing the P2ADB fault code.

The P2ADB fault code is related to the Reductant Quality Sensor in the automobile. This sensor measures the temperature and quality of the reductant fluid in the tank.

The Reductant Control Module detects the temperature signal from the sensor and sets the DTC if it is out of range low for more than 1 second. The specific issue indicated by the P2ADB code is a low voltage in the circuit of the Reductant Tank Temperature Sensor 2.

What are the possible causes of the P2ADB fault code in an automobile?

If you see the engine light on or the service engine soon warning light in your automobile, it could be due to the P2ADB fault code. This code is caused by a faulty reductant quality sensor, an open or shorted reductant quality sensor harness, a poor electrical connection in the reductant quality sensor circuit, or a faulty reductant control module. 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.
