: Have code P071 & P046

07-28-11, 11:13 AM
My car has been throwing codes and running rough for the passed few months. It shakes pretty bad (and sounds like a mis). I finally was able to pull the codes. I got two codes, P071 and P046.

P071: Intermittent Map Sensor Signal

P046: Front-To-Rear Bank Fueling Imbalance.

Whats my first step of solving these issues? I pulled my map off to make sure that gasket was not broken, its not broken. Is there sometype of mutimeter test I could do on the map plug? Could the intermittent map cause my fueling imbalance?

Update your profile to show the year and model of your car. It would help in determining the age and we wouldn't have to ask.

I'd probably start by replacing the MAP sensor.
