As a continuing drive to replace the oem sensors on my 1999 civic, I purchased a new map sensor from Amazon and did the replacement. All in all it took 25 minutes and it's an easy task to do.
First step was to remove my warm air intake filter.
Next I used power lube on the nuts and bolts of the throttle body and removed them.
Step 2: Removing the Old Map Sensor.
I unclipped the wire harnesses to the map and throttle position sensors. A Phillips head screwdriver I used to removed the two screws holding the map sensor. I also took out the oem of ring.
Step 3: Old and New Side by Side.
Here's a look at the old and new map sensors.
Step 4: Install New Map Sensor and Reinstall the Throttle Body.
Installation is the reverse of installation. Really easy job and the new map sensor will help ensure I have good fuel economy!
