SOURCE: were is the intake air temp sensor located on a 2001 chrysler 300m

P0112 is the code for a intake air sensor problem. If you can buy one seperate it will be located between the Air filter and the Throttle Body ... usally near the Mass Air flow sensor . I am a Jaguar Tech our are located inside the Mass Air sensor . Also ck the actuall housing of the air filter assembly

2014 Nissan Altima starts up fine but when you put it in drive it shuts off. Put it on the scanner and it read codes p0102 and p0112


This sounds more like a leak in the air intake system rather then what those 2 codes specify. Make sure all the intake tubes are securely tightened and all vacuum lines are crack free. Also make sure the air resonator box is securely tightened.

Check engine lght on and 2 codes p0103 and p0112


P0103 HYUNDAI - Mass or Volume Air Flow Circuit High InputPossible causes- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection
- Intake air leaks
- Faulty mass air flow sensor
Tech notesBefore replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
P0112 HYUNDAI - Intake Air Temperature Sensor 1 Circuit Low InputPossible causes- Dirty air filter
- Intake air temperature (IAT) sensor harness is open or shorted
- Intake air temperature (IAT) sensor electrical circuit poor connection
- Faulty intake air temperature sensor
When is the code detected?An excessively low voltage from the sensor is sent to ECM.

The Fault Code: P0112 IAT CKT Low Input on my 2000 Accent gl


P0112 - Intake Air Temperature Circuit Low Input
Usually the P0112 is caused by a bad IAT (internally shorted or open or otherwise damaged), but it could also be:
  • No reference voltage to the IAT sensor due to an open wire
  • Excessively high intake air temperatures
  • Short to ground on signal circuit
  • Damaged IAT connector
  • Bad PCM

Hello my check engine light is on i went to local parts house had them read the code low input voltage in the iat sensor so i bought a new one had the code cleared and before i left parking lot light was...


Keep in mind that the IAT (intake air temperature) sensor simply measures the temperature of air that is entering the engine. Intake air temperature is important because the higher the intake air, the higher the combustion temperatures. High combustion temperatures result in increased Nox (Nitrogen oxides) emissions. To keep these higher temps from causing increased combustion temps, the intake air tubing should be intact, allowing the engine to "breathe" air that isn't sampled from the engine compartment. The IAT measures air temp by using a thermistor, or a thermometer of sorts. The thermistor is supplied 5 volts reference voltage from the PCM (powertrain control module) and a ground. Usually, when the air temperature is cold the resistance in the thermistor is high and when the air temperature is warmer, the resistance decreases. This change in resistance changes the 5 V reference from the PCM, thereby informing the PCM of the temperature of incoming air. If the PCM notices that the incoming air temp is unusually high, say, 300 degrees, when the engine temp is still relatively low, it will set a P0112.

Symptoms: There may be no noticeable symptoms of a P0112 code other than an MIL (Malfunction Indicator Lamp). However, a emissions test may reveal higher Nox readings depending on the type of IAT failure. Or the engine may ping under load, depending on the type of IAT failure.

Causes: Usually the P0112 is caused by a bad IAT (internally shorted or open or otherwise damaged), but it could also be:
* No reference voltage to the IAT sensor due to an open wire
* Excessively high intake air temperatures
* Short to ground on signal circuit
* Damaged IAT connector
* Bad PCM

Possible Solutions:
Hook up your scan tool or code reader and read the IAT reading. With a cold engine, the IAT should roughly match the coolant reading, since both will read ambient temperature. If the IAT is reading excessively high, check the IAT connector for damage. If you find none, unplug the IAT sensor and recheck the reading. It should now read the minimum, around -20 deg. If it does, then replace the IAT sensor. But, if the reading is still high, unplug the sensor and check for resistance across the two wiring harness terminals. If there is infinite resistance, then the PCM itself is bad. If the resistance isn't infinite, then check and repair the short to ground on the signal circuit.

Keep us updated.

Looking for ways to correct my check enngine light; the following codes p01400 and p0112 on a 07 6 cycl trailblazer? be advised i just changed out the evap solenoid?


Well the code for the p01400 is for the evap solenoid. But, it could have a wiring problem.
The p0112 is for the intake air temperature (IAT) sensor.

Could they be related?
