Where is the IAT located on a jeep 4L?
The MAS (Mass Airflow Sensor) has a 4 pin connector to the combined MAS/IAT that sits on the throttle body housing. Jeep 4L Engines IAT Location: On the Jeep 4.0 engine, the IAT sensor is in the intake manifold behind the throttle body. Right below the tube leading into the engine.
When did Kia Optima start using OBD’s?
OBD-II review 1. OverviewThe California Air Resources Board (CARB) began regulation of On Board Diagnostics (OBD) for vehicles sold in California beginning with the 1988 model year. The first Engine Control Module (ECM).
What are the components of a Kia Optima?
A/C Pressure Transducer (APT) 21. Purge Control Solenoid Valve (PCSV) 23. CVVT Oil Control Valve (OCV) [Bank 1 / Exhaust] 24. Electric Waste Gate Actuator (EWGA) 25. RCV Control Solenoid Valve 26. Fuel Pressure Regulator Valve 27. Canister Close Valve (CCV) 28. Ignition Coil 29. Main Relay 30. Fuel Pump Relay 31. Data Link Connector (DLC) [16-Pin]
Where is my IAT air intake sensor : engine performance?
IAT is built into your MAF sensor. Must determine which wires are for the actual IAT. Its a combined unit with the Mass Air Flow sensor that is sticking out of your intake tube between air box and throttle body. V6 IAT is integrated into the Mass Air Flow Sensor.
Where is the IAT sensor on my air intake?
Step 1: Locate the sensor. The IAT sensor is usually located in the air intake boot, but it may also be located in the air cleaner housing or intake manifold. Step 2: Disconnect the negative battery cable.

Can a bad IAT sensor cause fuel economy problems?
The IAT sensor then varies its internal resistance according to air temperature and sends a return signal back to the PCM. The PCM then uses this formation to determine fuel injector control and other outputs. A bad IAT sensor can cause all kinds of drivability problems including a rough idle, surging, stalling, and poor fuel economy.
Where is the IAT located on a Honda Accord?
It should be in the intake tube (black tube from your filter) theres like a sensor (IAT)on it. Located in lower side of admission manifold, infront at firewall in driver side. IAT is on the left (driver’s) side of the intake manifold directly below the throttle body/throttle position sensor.
What happens when the IAT resistance goes up to 90 degrees?
So if the IAT resistance is equivalent to 80 degrees, the ECM will “see” it as 30 degrees. If it goes up to 90 degrees, the ECM will “see” it as 40 degrees. That way, if the ECM is programmed to compensate only by air temperature, you will have more fuel injected along the whole range of temperatures.
