The factors influencing the cost of diagnosing and fixing the automobile fault code p112b are the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges between $75 and $150.

The P112B fault code indicates that the Engine Coolant Temperature (ECT) is too low.

This code is set by the Engine Control Module (ECM) when it detects that the signal from the Engine Coolant Temperature Sensor is outside of the factory specifications.

The Engine Coolant Temperature Sensor is responsible for measuring the temperature of the engine coolant. This information is crucial for the ECM to make adjustments to the fuel mixture and ignition timing. When the ECT is too low, it can lead to poor engine performance, increased fuel consumption, and potential damage to the engine components.

If you encounter the P112B fault code, it is important to address it promptly. The first step is to check the Engine Coolant Temperature Sensor and its wiring for any signs of damage or corrosion.

If necessary, the sensor should be replaced with a new one that meets the manufacturer’s specifications. Additionally, it is recommended to inspect the coolant level and ensure that it is at the proper level. By addressing the P112B fault code, you can ensure optimal engine performance and prevent further damage to your vehicle.
