If everything passes physical inspection, you can test the MAP sensor using a digital multimeter set to 20V and a vacuum pump. If your voltage differs greatly on either test or the voltage change is erratic, the MAP sensor is faulty and will need to be replaced. Note: Depending on the vehicle and if a trouble code was set, a diagnostic tool may be required to reset the check engine light.

An o-ring is used to seal the sensor to the intake manifold Fig. 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.
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. 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. The MAP Manifold Absolute Pressure sensor should be located just in front of the throttle position sensor toward the back of the left side of the engine assuming you are standing in front of it facing it. If you have access to a volt meter, I would recommend testing it for power. If this checks out fine, then this likely points to a vacuum leak.
Vacuum leaks can be very difficult to trace. I would recommend having an expert from YourMechanic come to your home to diagnose your stalling issue firsthand for an accurate repair.
