- Precise measurement: Made to Bosch's OE specifications for precise manifold pressure readings and dependable engine management.
- Data for the ECM: Sends intake manifold pressure data to the engine control module, which uses it for fuel injection and ignition timing.
- Made for the engine bay: Designed to withstand extreme temperatures, vibration, moisture and contaminants. A fast response time supports precise signal output.
- Straightforward install: Matches the original mounting points and electrical connector, so no modifications are required.
Bosch tests every MAP sensor for performance, signal accuracy and reliability.
The sensor has one rectangular male connector with blade terminals. The listed applications use one sensor, and the package contains one manifold absolute pressure sensor. Country of origin: Germany.
Signs a MAP sensor may need replacing include a check engine light, rough idle, hesitation or poor fuel economy. These symptoms can have other causes, so diagnose the system before replacing the sensor.
