How to Replace a Map Sensor on a 1995 Dodge Intrepid

In 1993, Dodge released an all-new sedan known as the Intrepid. The initial generation of the Intrepid lasted through 1997, and it was one of the first "cab forward" Dodges. The 1995 Intrepid came standard with a 161-horsepower, 3.3-liter V-6 engine and had a 214-horsepower, 3.5-liter V-6 engine available. Both engines used a manifold absolute pressure sensor to measure the vacuum inside the intake manifold and send that information to the Intrepid's computer. Not replacing a failed MAP sensor can lead to a poor running condition and eventual engine failure.

Instructions

The 3.3-Liter Engine

1

Look on the rear of the intake manifold plenum and locate the manifold absolute pressure sensor. Press the locking tab on the MAP sensor's wiring harness and unplug the wiring harness.

2

Remove the two bolts securing the MAP sensor to the intake manifold plenum, using a ratchet and socket. Pull the MAP sensor from the intake manifold plenum.

3

Insert the new MAP sensor and tighten the bolts to 7 to 8 foot-pounds, using a torque wrench and a socket. Plug the wiring harness into the MAP sensor. Listen for it to click into place.

The 3.5-Liter Engine

4

Look on the driver's side of the intake manifold plenum and locate the MAP sensor. Unplug the MAP sensor wiring harness by lifting up on the locking tab and pulling the harness from the sensor.

5

Remove the MAP sensor, using a ratchet and socket. Note: the MAP sensor has a small bolt-like protrusion on the bottom part of it; use the socket on this protrusion to remove it.

6

Apply thread sealant to the threads on the new MAP sensor, if it doesn't come already coated. Install the new MAP sensor and tighten it to 7 to 8 foot-pounds with a torque wrench and socket. Slightly tighten the MAP sensor beyond 7 to 8 foot-pounds, using a ratchet and socket, until the sensor is horizontal.

7

Plug the wiring harness into the new MAP sensor until it clicks into place.
