P0127 2006 Nissan Altima Sedan Code - Intake Air Temperature Too High
Quick Answer
The Intake Air Temperature (IAT) sensor is variable temperature sensitive resistor that measures the temperature of the air in the intake system. Common causes include 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. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0127 2006 Nissan Altima Sedan Description
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.
The Intake Air Temperature (IAT) sensor is part of the Mass Air Flow (MAF) sensor (Air Flow Meter).
What are the Possible Causes of the DTC P0127 2006 Nissan Altima Sedan?
- 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
