When it comes to diagnosing and repairing issues with Ford vehicles, the code P0112 is an important one to know. This code indicates that there is an Intake Air Temperature Sensor 1 Circuit Low (Bank 1) error. This means that the intake air temperature (IAT) signal voltage is lower than the minimum calibrated limit. Understanding this code’s causes and potential solutions can help Ford owners get back on the road quickly and safely. To help with that understanding, here is a table outlining the causes and potential solutions for Ford Code P0112.

Causes and Solutions for Ford Code P0112
| Cause | Solution |
|---|---|
| IAT circuit short to ground | Check wiring, repair or replace damaged wires, and ensure a secure connection between the IAT and the ground. |
| Incorrect harness connection | Verify that the IAT is correctly connected and secured in place. |
| Damaged mass airflow/intake air temperature (MAF/IAT) sensor | Replace the MAF/IAT sensor if it is not reading correctly. |
| IAT_V PID reading less than 0.1 volts with ignition ON, engine OFF | Check the IAT_V PID reading with a scan tool to ensure it is reading correctly. |
When it comes to Ford vehicles, the code P0112 is a critical one to know. This code signals an Intake Air Temperature Sensor 1 Circuit Low (Bank 1) malfunction. In other words, the intake air temperature (IAT) signal voltage is lower than the minimum calibrated limit. It’s essential for Ford owners to have a basic understanding of the causes and potential solutions for this code in order to keep their vehicles running smoothly and safely. Having this information can help prevent costly repairs and long downtimes. By following the diagnostic process outlined here, Ford owners can quickly identify the cause and potential solutions for Ford Code P0112.

IAT Circuit Short to Ground
When the IAT circuit is shorted to ground, the IAT signal voltage will be lower than the minimum calibrated limit, triggering Ford Code P0112. To resolve this issue, the technician should inspect the wiring for damaged or lose connections, repair or replace any damaged wires, and ensure a secure connection between the IAT and the ground.
Incorrect Harness Connection
If the IAT is not connected correctly or secured in place, this can also cause Ford Code P0112. The technician should check the IAT connection to ensure it is connected correctly and secured.
Damaged MAF/IAT Sensor
If the MAF/IAT sensor is not working correctly, this can also trigger Ford Code P0112. The technician should use a scan tool to check the IAT_V PID reading, and if it is lower than 0.1 volts with the ignition ON and engine OFF, the MAF/IAT sensor should be replaced.
