The automobile fault code P112A indicates a problem with the engine coolant temperature.

When this fault code appears, the engine light or service engine soon warning light will turn on. The possible causes for this issue include low engine coolant, a faulty thermostat, a faulty engine coolant temperature sensor, an open or shorted engine coolant temperature sensor harness, or a poor electrical connection in the engine coolant temperature sensor circuit. To fix this problem, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion.

Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors.

The repair time for this issue is estimated to be around 1.0 hour.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p112a fault code.

  • The symptoms of the automobile fault code P112A include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p112a can be caused by various factors, including low engine coolant, a faulty thermostat, and a malfunctioning engine coolant temperature sensor.

  • The fault code P112A can be caused by the following: low engine coolant, faulty thermostat, faulty engine coolant temperature sensor, open or shorted engine coolant temperature sensor harness, and poor electrical connection in the engine coolant temperature sensor circuit.

To fix the automobile fault code p112a, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p112a, first, check the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • The estimated repair time for this fix is 1.0 hour.

The automobile fault code P112A can be diagnosed and fixed within an estimated repair time of 1.0 hour. Most auto repair shops typically charge between $75 and $150 per hour for their services.

The P112A fault code is related to the Engine Coolant Temperature Sensor (ECT). The Engine Control Module (ECM) constantly monitors the signal from the ECT to ensure it is within the specified range. When the ECM detects that the ECT is reading a temperature that is higher than the maximum limit set by the manufacturer, it triggers the P112A fault code.

This code indicates that the ECT is reporting an implausible maximum temperature reading. When the P112A fault code is triggered, it means that the Engine Coolant Temperature Sensor is not functioning properly.

This sensor is responsible for measuring the temperature of the engine coolant and providing this information to the ECM.

If the sensor is reporting a temperature that is higher than what is physically possible, it can lead to incorrect engine management decisions and potentially cause engine damage. To fix the P112A fault code, the first step is to inspect the Engine Coolant Temperature Sensor and its wiring for any signs of damage or corrosion. If any issues are found, they should be repaired or replaced as necessary. Additionally, it may be necessary to reset the fault code using a diagnostic tool after the repairs have been made.

It is important to address this issue promptly to prevent further damage to the engine and ensure optimal performance.
