P0127 2005 Infiniti G35 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 2005 Infiniti G35 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.
Some manufacturers incorporate the Intake Air Temperature (IAT) sensor as part of the Mass Air Flow (MAF) sensor (Air Flow Meter).
What are the Possible Causes of the DTC P0127 2005 Infiniti G35?
- 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 to Fix the DTC P0127 2005 Infiniti G35?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
