depends on which motor you have-4 cyl should be in the intake manifold-v-6 should be in the air snorkle tube coming from air filter housing
Where is the Air Intake temperature sensor located on a 1997 dodge ram 1500?
The air intake temperature sensor can be found on the top of your manifold intake. The sensor will be right in the middle of the intake manifold.
the Intake Air Temperature Sensor (IAT) could also be called the Manifold Air Temperature Sensor (MAT) some instances they are both.
INTAKE AIR TEMPERATURE SENSOR HIGH
It should be the plug on the intake just before the Throttle Body.
the iat is built into the mass air flow sensor attached to the intake tube
The air intake sensor on a 2003 Dodge Durango is located inside the cool air intake at the front of the engine compartment. It allows the engine to make adjustments based on the temperature of incoming air.
in the air cleaner
take a look at the intake tube (between the air box and the engine) it is the larger plug on the backside of the stock intake.
There are two, the ambient air temp sensor on the cold air intake just before the filter. And the Intake temp sensor on the intake itself (throttle body after the MAF.)
