Engine Performance problem
2000 Dodge Caravan 6 cyl Two Wheel Drive Automatic 140000 miles
This message is to Dave H.
In reference to the codes on the computer I got an answer from the readout of the code from an auto zone store before I took the car to my mechanic
The code said
Fuel trim bank one condition
The powertrain control module uses the oxygen sensor to calculate the Air/Fuel ratio of the engine. The coputer has recognized a rich or lean condition on one engine bank only.
If bank one and two codes set together suspect fuel pressure or MAF ( mass air flow) sensor
Oxygen sensor defective
ignition misfire- repair
Fuel injector problem
What should I do?
Please could you use the reply button at the bottom of this post to reply or when you post in the future .. this way I am advised you have replied !! thanks.
First thing you need to do is remove and clean the MAP sensor using sensor cleaner from an autoparts store !! follow the directions on the container !!
Manifold Absolute Pressure (MAP) Sensor (2.4L)On front of intake manifold.
Manifold Absolute Pressure (MAP) Sensor (3.0L)On front of intake manifold.
Manifold Absolute Pressure (MAP) Sensor (3.3L)On rear of intake manifold.
Manifold Absolute Pressure (MAP) Sensor (3.8L)On rear of intake manifold.
