Where is my MAP Sensor located and how do I get to it?

The Manifold Absolute Pressure (MAP) sensor is mounted into the front of the intake manifold (Fig.18). An o-ring is used to seal the sensor to the intake manifold (Fig. 19).

(1) Disconnect electrical connector at sensor.

(2) Clean area around MAP sensor.

(3) Remove 2 sensor mounting screws.

(4) Remove MAP sensor from intake manifold.

(5) Check condition of sensor o-ring (Fig. 19).

The part is extremely hard to get to. The sensor broke in half while trying to remove the housing to get to the Thermostat sensor. It’s as if you need a special size tool to remove the bolts. Any advice on how I can remove the old sensor?

Hi Wendy. I replacement my MAP sensor and found that by removing the plastic box on top of the engine really helps. This will allow you to have better access to the part. I have seen a few posts about replacing the MAP sensor and NO ONE says to use a 7 mm socket or wrench! None of my one-quarter rachets would fit into the very small space to remove the left side 7 mm hex head screw. The RH side of the part, I removed with a 7 mm box wrench. I went to Autozone and found a "mini rachet" that is one quarter inch drive. The total length is 3.5 inches but the head of the rachet is only 5/8 in wide and only 1/2 thick. Got home and it just fit into the confined space and I was able to remove the bolt. I hope this helps somebody out there.......Hal from Bradner OH
