Were is the intake air temp sensor located on a 2001 chrysler 300m

This should help. How to Test the Intake Air Temp IAT Sensor GM 4 8L 5 3L 6 0L

In the air intake of the engine. Usually combined with air flow and pressure sensors.

Code 1297 is for the MAP sensor voltage no change, and code 112 is for low voltage from the intake air temp sensor.
I would look for a problem with the wiring harness for the two first.

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.

it is a code for a air temp sensor going to the intake look near the air filter to intake tube

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.

its the intake air temp sensor located on the air duct between the throttle body and the air filter housing

Hi,
On2.7L models, the IAT sensor is located on the left side (driver) of the Intake Manifold plenum, if you are standing in front of the car, it is the sensor right before the two vacumm hoses plugged into the Intake Manifold.

On 3.2L/3.5L models, the IAT sensor is incorporated whthin the Map sensor which is also located on the left side (driver) of the upper Intake Manifold plenum. Right by the coolant reservoir tank.

Good Luck

intake temp sensor is on the intake tube down from the air filter

yep po132 shorted to voltage po152 shorted to voltage.this means lean conditions .you got in take leak .if you get a high voltage conditions you got rich mixture.bad plugs or stop up air filter.
