P0112 2011 NISSAN SENTRA Code - Intake Air Temperature Circuit Low Input
|P0112 2011 NISSAN SENTRA code possible causes
- 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 is the P0112 2011 NISSAN SENTRA 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.
|P0112 2011 NISSAN SENTRA code tech notes
Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compressed air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replace the mass air flow sensor.
|What is the cost to diagnose the P0112 2011 NISSAN SENTRA code
The cost to diagnose the P0112 2011 NISSAN SENTRA code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
|When is the P0112 2011 NISSAN SENTRA code detected?
An excessively low voltage from the sensor is sent to ECM.
|What are P0112 2011 NISSAN SENTRA code possible symptoms?
- Engine Light ON (or Service Engine Soon Warning Light)
|What is P0112 2011 NISSAN SENTRA code meaning?
The Intake Air Temperature
(IAT) sensor is built into mass air flow sensor or in some vehicles mounted to the air filter duct housing. The sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM
).The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rise. The Intake Air Temperature
signal is used as an input for various systems in the vehicle.
