Details of the Mazda p0112 OBD Code

Mazda P0112 indicates an issue with the intake air temperature sensor circuit low input.

Mazda OBD code P0112 indicates an issue with the Intake Air Temperature (IAT) sensor circuit.

This code is triggered when the Engine Control Module (ECM) detects that the IAT sensor signal voltage is lower than expected.

The IAT sensor is responsible for measuring the temperature of the incoming air into the engine.

A lower than expected voltage from the sensor can lead to incorrect fuel delivery and potentially affect engine performance.

When this fault code is set, it typically points to a problem with the IAT sensor itself, the wiring/connectors associated with the sensor, or a potential issue with the ECM’s ability to receive the correct signal from the sensor.

Mechanic’s Tech Notes

Detailed information on diagnosing and repairing fault code P0112 in Mazda vehicles.

To diagnose and fix OBDII code P0112 on a Mazda, start by checking the intake air temperature (IAT) sensor circuit.

Use a voltmeter to test the sensor’s resistance and compare it to specifications.

Inspect the sensor and its wiring for any damage or corrosion.

Ensure the sensor is securely connected.

If the sensor and wiring are okay, the issue may lie with the PCM.

Use a scan tool to monitor IAT sensor data and check for any discrepancies.

If necessary, reflash the PCM to address any software issues.

Remember to clear the code after making any repairs.
