Code P1296 Dodge Description

The P1296 code for Dodge vehicles indicates that there is no 5-volt reference voltage being supplied to the Manifold Absolute Pressure (MAP) sensor. The MAP sensor is a crucial component that measures the pressure within the intake manifold and provides this information to the engine control module (ECM) to adjust fuel delivery and ignition timing. The 5-volt reference voltage is essential for the proper functioning of the MAP sensor, as it allows the sensor to accurately measure the pressure changes in the intake manifold.
