Code P0112 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 P0112 2006 Nissan Altima Sedan?
- Faulty Intake Air Temperature (IAT) sensor
- Dirty air filter
- Intake Air Temperature (IAT) sensor harness is open or shorted
- Intake Air Temperature (IAT) sensor circuit poor electrical connection
How to Fix the DTC P0112 2006 Nissan Altima Sedan?
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.
