P1114 — Intake Air Temperature Sensor Circuit Low Input

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Mazda

About P1114

P1114 is a manufacturer-specific powertrain diagnostic trouble code recorded for Mazda vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1114 is stored, the module has detected a signal or supply voltage lower than the expected operating range; and a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1114 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

DTC P1114 is set on Mazda vehicles when the Engine Control Module (ECM) detects that the Intake Air Temperature (IAT) sensor signal voltage has fallen below the normal operating range, a condition described as circuit low input. The IAT sensor is a negative temperature coefficient thermistor, so a low signal voltage corresponds to the ECM reading an unusually high air temperature. This is most often caused by the signal wire shorting to ground or by an internally shorted sensor rather than a genuinely hot intake. With a falsely high air temperature value the ECM may lean the fuel mixture or re...
