The downstream O2 sensor will probably fix the catalyst efficiency code. That code usually pops up when a new sensor is on the front and the old and slower sensor is still on the rear. The PCM compares them to decide if the converter is working. The airbag and cruise is probably a bad clockspring. It lives right behind the steering wheel. Disconnect the battery before attempting repairs on the airbag system for your own safety. You don't want an accidental deployment while working that close. I hope this helps.

Where is the engine ecm located on a 2001 Dodge Grand Caravan 3.3L


Rebecca, first thank you for providing year engine size and the fact that it's a flex fuel van. Your ECM [engine control module or engine computer] is located right in front of the battery. This is an INCREDIBLY stupid place to put it [not to mention placing the fuse/relay box just outboard of the battery on this van] It is critical to keep the battery clean on this van, as any build up of dried battery acid will make it's way into the ECM and/or the fuse/relay box. The acid will do all sorts on nasty damage to these parts. They should shoot the idiot who designed the electrical system on these vans. FYI, I'm a professional mechanic with 40 years experience.

air in the system .before doing all that .you should have put a dadiator flush in the expansion bottle .then run it for about 20 miles then drain it.you do this to clean out the radiator core of dirt and rust.and it cleans the heater core .then bleed the air out by turning your heater of full .run the engine till water starts to get hot .then refit the cap.

I have a 2001 Dodge Grand Caravan Sport w/ 3.3l flex fuel and the van is idling odd. I have changed the MAP sensor, the IAC sensor, and the spark plugs and wires, and no change.


Could be that your coil pack has gone bad. This is not a cheap piece though, so you will want to be sure.

Does it run fine when up off of idle, or does it also seem to be missing as you drive down the road.

2000 grand caravan won't go above 70 mph. high rpms


First I need to ask is it a 4 speed or a 3 speed transmission. If it's a 4 speed when driving down the road pull it from drive to third gear. You shpuld hear the engine speed up if it does not then that means you have on 4th gear and you will have to take it to a transmission shop. If it's a 3 speed then just count the shift points if all 3 gears are present then drive down the road and see if the van goes into tcc. When you mean the rpms are high how high are they.
