Q: Misfire due to bad ecm

asked by on

Where is ecm located

My car has 175000 miles.
My car has an automatic transmission.

Hi There, The ECM on your Dodge Caravan is located inside the driver’s fender on the frame,toward the front bumper. As you know, there are many things that can cause a misfire aside from the ECM. I would suggest removing the ECM and having it tested to determine if this is what may be causing the misfire.
