P0127 2013 NISSAN ROGUE Possible Causes

  • Faulty Intake Air Temperature (IAT) sensor
  • Intake Air Temperature (IAT) sensor harness is open or shorted
  • Intake Air Temperature (IAT) sensor electrical circuit poor connection

How is the P0127 2013 NISSAN ROGUE code repair?

Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.

Tech Notes

You can try to clean the sensor first and reset the code, if the code comes back the Intake Air Temperature (IAT) sensor which is part of the Mass Air Flow that will need to be replaced to fix the problem.

P0127 2013 NISSAN ROGUE Meaning

The Intake Air Temperature (IAT) sensor is variable temperature sensitive resistor that measures the temperature of the air in the intake system. Sensor resistance will change based on air temperature. The higher the temperature is, the lower the resistance. The Engine Control Module (ECM) provides a reference voltage and monitors the voltage drop between a fixed value internal resistance and the sensor resistance. This is called a voltage divider circuit.
IAT sensor values are used by the ECM processor to assist with the calculation of idle speed, fuel mixture and spark advance.
Inaccurate voltages from the IAT sensor may affect pulse-width, idle quality, and tail pipe emissions. Intermittent signals may cause hesitation, stumble and surging. If an IAT sensor failure accompanies an Engine Coolant Temperature (ECT) sensor failure, cooling fan operation may also be affected.
Some manufacturers incorporate the Intake Air Temperature (IAT) sensor as part of the Mass Air Flow (MAF) sensor (Air Flow Meter).
