Details of the Nissan p0111 OBD Code
Nissan P0111 indicates an issue with the intake air temperature sensor circuit performance.
OBD code P0111 for Nissan vehicles indicates an issue with the Intake Air Temperature (IAT) sensor circuit.
This code is triggered by the Engine Control Module (ECM) when it detects that the IAT sensor signal is out of the specified range or is not correlating with other sensor signals in the system.
The IAT sensor is responsible for measuring the temperature of the incoming air to the engine, helping the ECM adjust fuel delivery and ignition timing for optimal performance.
If the IAT sensor is faulty or there is a wiring issue in the circuit, the ECM will set code P0111.
