A 2001 Grand Caravan w/3.8L V6, just over 100K miles. When cold, a loud knocking sound happens when engine is rev'd. Once the engine warms up, the knocking can be heard at idle. The engine warning light is on.
I believe it might be the knock sensor that has gone bad. If so, where is it located on this engine.
If you have any other suggestions, I'm all ears.

where is knock sensor on 2000 3.8l dodge caravan? engine block or ecm?
could be piston slap. not much you can do short of rebuilding motor if this is the case
Knocking or rattling/pinging sound? If it is a knock, that's not a good sign, and first thing I'm going to ask is if oil level is up & when was it last changed along with filter. When did noise occur?
The engine has a slight knock its not very loud but u can tell is still there
