Gas engine and year fitment
The idle air control valve sits on the throttle body of gas fuel-injected engines. On the 1995-2003 Ram 2500, that means the 5.2L V8, 5.9L V8 and 8.0L V10. Diesel trucks do not use this kind of valve. Cab, bed, 2WD or 4WD and trim do not change the valve, but the engine and throttle body do.
Catalogs show different valves within the range. Standard Motor Products lists the AC416 for 2000-2003 trucks, separate from earlier applications. The 2003 model year is a body change year, so check the production date. Match the connector, terminal count, mounting pattern and pintle size to the valve you remove.
Symptoms of a bad IAC valve
A failing idle control valve can cause a surging or unsteady idle, stalling when you let off the throttle, an idle that is too low or too high, and a rough idle when the engine is cold or the AC kicks on. The usual causes are an electrically failed motor, a pintle stuck with carbon, or a damaged connector or seal.
Vacuum leaks, a dirty throttle body, a bad throttle position sensor and wiring faults cause the same symptoms. Check those before you replace the valve.
Installing the new valve
Some valves come with a seal or O-ring and some do not, so check the listing. Remove the old valve from the throttle body and inspect the air passage and gasket.
Clean carbon from the throttle body passage, but do not force or twist the pintle on the new valve. Use a new seal if the old one is damaged. Check the connector for corrosion or broken terminals before you plug in the new part. Idle relearn steps, if any, depend on your engine and the valve maker, so follow the instructions supplied.

Ram 2500 questions
Does a diesel Ram 2500 have an idle air control valve?
No. The idle air control valve is used on the gas fuel-injected engines, such as the 5.2L and 5.9L V8 and the 8.0L V10. Cummins diesel trucks do not use this part.
Which IAC valve fits a 2001 Ram 2500?
Standard Motor Products lists the AC416 for 2000-2003 Ram 2500 and 3500 gas trucks, but confirm your engine in the fitment table and compare the connector with your old valve.
Can a dirty throttle body cause idle problems on my Ram 2500?
Yes. Carbon in the throttle body or the IAC passage can cause a rough or surging idle. Clean the passage when you replace the valve, and check for vacuum leaks too.
