Your IAT sensor is going to be on the intake tube.
the connector you should see is a oval two wire connector. (the normal for chevys) the other connector going to the intake tube is the mass air flow, these usually have 4-6 wires.

SOURCE: IAT sensor plug 2004 Ford F150

The MAFS and IAT are in a single connector on the 04-08 MY F-150s.
This is for a new body style 2004, not the Heritage / Lightning models.

The IAT sensor is the Gray w/ Red stripe & Gray wire pairs in the connector. The connector is a 6 pin ( 1 row of 6 pins ) black connector.

I swapped out the plug wires and plugs with Denso, while I had the covers off decided to wash engine, engine ran fine. Next day started engine and the idle constantly oscillated between 1200 to 1400 RPM....


You are right this is a classic MAF problem or rather the air mass meter AMM which is the MAF working with the closely associated intake air temperature sensor IAT(a little bead like thermistor on wire sitting close to the MAFF in the air stream). The ECU was getting poor information from the MAF. The ECU had to rely on slow input signals from the IAT and feedback from the oxygen sensor on the exhaust to keep the engine running. The ECU hunted for the right mix, first rich and then lean but never settling hence the 'surge and slow' of the engine revs. When you disconnected the MAF you also disconnected the IAT and now the ECU had just the one signal from the oxygen sensor to depend on and so now provides a slightly rich mix giving the rough idle. You have done the hard work just change the MAF and IAT assembly.

Location of IAT sensor in the car?


For Hyundai Car 1999-05 - Intake Air Temperature (IAT) Sensor Location (check several options):

1.- The IAT sensor is located against the firewall to the left side of the engine. It is combined with the Manifold Absolute Pressure (MAP) sensor.

2.- This sensor is located in the air intake plenum assembly. On some vehicles this sensor is combined with the MAP/MAF sensor.

3.- The IAT sensor is located in the air plenum assembly. On some vehicles it is combined with the MAF sensor.

4.- This sensor is located in the air intake plenum assembly. On some vehicles this sensor is combined with the MAP/MAF sensor.

5.- This sensor is located in the air intake plenum assembly. It is combined with the Manifold Absolute Pressure (AFS) sensor.

6.- This sensor is located in the air intake plenum assembly. It is combined with the Manifold Absolute Pressure (AFS) sensor.

Spark plugs


The spark plugs on the cavalier are under the 2.2 ecotec panel located on the top of the engine. There are no spark plug wires to deal with. The electronic coil pack directly attaches to the plugs with rubber seats like in a spark plug end. Then you use a deep socket ratchet to get the plugs out. Use anti-seize compound when replacing the plugs.

2002 chev avalanche mat sensor


I assume you are looking for the wiring for the IAT because MAT sensors are no longer used..

here you go

black / white - PCM ground
pink - fused 12-volts
yellow - MAF signal
tan - IAT sensor signal
black - IAT sensor ground

manifold temp. sensors are no loner used.

I believe you are looking for the IAT "intake air temp sensor" which is part of the mass air flow sensor.

good luck

Locate IAT sensor


Hi

Follow the plastic intake tubing from the air box. You will first come across the MAF sensor which is located right next to the airbox. Keep following the tubing. You are looking for a small sensor plugged into the tubing. It should only have a two wire plug to it.

If you cant find it then look on the intake manifold itself, and if it is not there then it is built into the MAF sensor.
