    Yes, car started "sputtering" and progressively got worse until the "check engine" light came on. Took it to Autozone, and they hooked it up to their "machine". The reading said it was running "too rich", and that it could be due to a bad oxygen sensor or map sensor. My husband isn't super "mechanically inclined" as far as cars are concerned, but he's been told that the oxygen sensor is something he could probably change on his own. Not sure about the map sensor....

They are in the exhaust system. one upstream that controls fuel mixture and one downstream that reports on oxygen content in exhaust to report emissions failure. Is check engine light on?

If not, why would you change it?

Oxygen sensor, the powertrain control module controls the electrical circuit for the oxygen sensor heater. where do you find this and the relay


the heated oxygen sensor(HO2S) is located in the exhaust manifold/s before the cat converter/s
O2 sensors are located after the cat converters
the power train is the engine and transmission unit and the control for the sensors is the ECM
the major problem is the wires in the HO2S as they are fragile and break close to the sensor very easily

Location of oxygen sensors on 2002 dodge grand caravan with 3.3 liter engine after considerable maintance work done by a dodge dealer my gas mileage dropped by as much as 6 to 8 miles per gal. after a time...


The o2 sensors are located on the exhaust system.The upstream in on the rear exhaust manifold and the down stream is in front of the catalytic converter.Usually when they are bad they will make the check engine like go on.Make sure the air filter is clean,tires at correct inflation,alignment is to specs.If the vehicles pulls to one side or the other or steering wheel is not straight when driving down a straight stretch of road.Also tires are wearing normal.Use cruise control where ever on highway.If you let your vehicle warm up in winter.This also uses gas.Hope this helps.Good luck.
