1989 Ford Ranger

Engine Performance problem
1989 Ford Ranger 6 cyl Two Wheel Drive Automatic 95000 miles

Can a backyard mechanic like myself replace a MAP sensor on an 1989 Ford Ranger with a V-6? The dealer wants almost $300.00 to do the job with almost $220.00 in labor I know everyone has to eat but I think that this is excessive

Thanks Joe

Yes you should be able to change this yourself. Look for the vaccum routing diagram under your hood. The actual name is a VECI Vehicle Emissions Control Information Label. This diagram should tell you where the MAP sensor is located. It usually only has two screws a vaccum line and an electrical connector. Real easy to change. Good Luck

Just a little add on to the toolmans post !

Manifold Absolute Pressure (MAP) Sensor
MAP sensor measures absolute pressure of mixture in intake manifold and sends a proportional signal to the ECA. It is mounted on right inner fender for 5.0L engine and left inner fender for all others. A vacuum hose is connected between the sensor and the intake manifold.
