P0112 Fault-Error code IAT Intake Air Temperature Circuit Low Input

What is P0112 Fault-Error code?

P0112 Fault-Error code is an error code identified by the OBD-II (On-Board Diagnostics II) system and is associated with the IAT (Intake Air Temperature) sensor. This error code indicates that the temperature sensor in the IAT sensor is signaling low temperature or is not working.

The meaning of P0112 Fault/Error code is as follows

• P0112 Malfunction/Error code: IAT Sensor Temperature Low Circuit

P0112 Fault/Error code Causes

1. Bad or faulty IAT sensor.

2. Electrical problems, broken or loose wires in the IAT sensor circuit.

3. Cold air leaking or improper placement of the sensor in the airflow.

P0112 Fault/Error code Symptoms

1. Erratic engine operation, especially in cold weather.

2. Decrease in fuel efficiency.

3. Engine power loss.

4. "Check Engine" or "Service Engine Soon" light comes on.

How to Determine P0112 Fault/Error Code

1. Trouble/Error code P0112 is usually diagnosed using an OBD-II scanner or code reader. These devices can receive the error code by connecting to the computer on the vehicle.

2. The error code is recorded by the vehicle's computer system when the problem occurs and becomes accessible through the OBD-II scanner.

P0112 Fault/Error code Errors Made While Correcting

1. Just replacing the sensor without checking the IAT sensor or ignoring any other possible problems.

2. Failure to check or repair electrical connections.

P0112 Fault/Error code Severity

The severity of the P0112 Fault/Error code is generally considered to be a minor fault that affects the usability of the vehicle. However, this error can have a negative impact on fuel efficiency and engine performance. It is important to resolve the problem early as neglecting it can lead to further damage.

P0112 Fault/Error code Repairs

To deal with the P0112 Fault/Error code, the following can be done:

1. Replacement of faulty IAT sensor.

2. Checking electrical connections and repairing them if necessary.

3. Elimination of cold air leak or reinstallation of the IAT sensor in accordance with the air flow.

P0112 Fault/Error code Things to Consider

If you encounter a P0112 Trouble/Error code or the "Check Engine" light is on, it is important to diagnose the problem and have it repaired immediately. Ignoring the problem can affect the engine's efficiency and increase fuel consumption. It is recommended to resolve the issue by contacting a qualified mechanic or technician.
