I am helping work on my mothers van which is the van stated above. I took it to the "zone" to run a check engine code and was asked a confusing question. Which model of the 3.3L did we have? I wanted to know if this may affect 02 sensor choice to because I do not want to pay their higher prices. On the gas door it does say we can run E85 but does not have a yellow cap. Any help would be greatly appreciated.

 

If you want to buy O2 sensor, the best way to save is avoid Autozone O2 sensor altogether. Go to the dealer and pick up the right one according to the Vin.

10 out of 10 times the sensor you buy from the Zone are wrong anyway. Especially if you buy a Bosch brand one.

Before we had the E85 fuel, Chrysler and dodge had the flex fuel. Which was almost the same. The only time you need to worry about the fuel cap is on the New Diesels. Because now the owner now has to add DEF fluid, I believe every other fill up. I agree with steak59, buy mopar parts.
