Dodge Repair Questions? Ask a Mechanic for Answers ASAP
On this system we want to start with the smallest code, which is the code 13. Once we correct this problem if the other codes continue to return we will address those codes at that time. So start by making the following test.
Test the voltage at the Manifold Absolute Pressure Sensor (MAP) at key on, engine off. Normally at sea level it will be about 4.5 volts. Start the engine and take a second reading of the MAP sensor voltage. With good vacuum supply getting to the sensor, the voltage will normally come down to about 1.3 volts.
What is the engine size?
Its on the left side of the throttle body.
Is that the middle wire on the sensor you are checking?
The middle one should be 1.3.
What kind of problems are you having with the vehicle besides the codes? and is the check engine light on all the time
