Help your engine computer keep track of intake manifold pressure with the Spectra Premium Manifold Absolute Pressure (MAP) Sensor, part number MP102. It fits many vehicles, among them the 1988-1998 Chevrolet C1500, the 1988-1995 Chevrolet K1500 and the 1987-1995 Jeep Wrangler, and serves as a direct-fit replacement for the listed applications.
A MAP sensor reads the pressure, or vacuum, inside the intake manifold and sends that signal to the engine control module. The module uses this reading, along with other inputs, to help calculate fuel delivery and ignition timing as engine load changes.
Signs a MAP sensor may need replacing include a rough or unstable idle, hesitation or stumbling on acceleration, reduced fuel economy and an illuminated check engine light. These symptoms can have other causes, so diagnose the system before replacing parts. If a failed MAP sensor is the cause, the MP102 replaces it.
See the Buyer's Guide tab for the full list of vehicles and engines this sensor fits.

What does a manifold absolute pressure sensor do?
It measures pressure, or vacuum, in the intake manifold and sends that signal to the engine control module. The module uses it with other inputs to help set fuel delivery and ignition timing.
What are signs a MAP sensor may need replacing?
Common signs include a rough idle, hesitation on acceleration, lower fuel economy and a check engine light. Other faults can cause the same symptoms, so diagnose the system before replacing the sensor.
How is the MAP sensor installed?
Installation generally means disconnecting the electrical connector and any vacuum hose, removing the old sensor and fitting the new one. Follow your vehicle's service information for the exact procedure.
