Code P1187 Dodge Description
The P1187 diagnostic trouble code (DTC) for Dodge vehicles refers to an issue with the Throttle Inlet Pressure/MAP (Manifold Absolute Pressure) Correlation. This code indicates that there is a discrepancy between the throttle inlet pressure and the MAP sensor reading in the vehicle's engine. The MAP sensor is responsible for measuring the pressure within the intake manifold, which helps the engine control module (ECM) adjust the air-fuel mixture for optimal combustion. When the correlation between the throttle inlet pressure and the MAP sensor reading is off, it can lead to various performance issues in the vehicle.
