Cadillac Repair: Map Sensor Location, cadillac fleetwood, vacuum hose

Question
Can you please tell me where the map sensor is located on a 1983 Cadillac Fleetwood Brougham?

Answer
If you open the glove box and remove the glove box liner and then remove the big black plastic panel that is under the dash on the passengers side you will see a black vacuum hose under the dash going to the sensor which is located behind the dash in that small space between the glove box opening and the end of the dash. If you get a mirror and put it in the glove box opening look over to your right hand side behind the dash.

IF you find that there are 2 sensors, One is the MAP and the other is the BARO sensor. ONLY the MAP has the vacuum hose on it.

IF the sensors are the ROUND metal style, You MUST replace BOTH the MAP & BARO with the newer style flat black plastic style.

There was a service bulletin and a KIT that you moved the MAP sensor from behind the dash to the engine compartment and install it on the passengers side plastic wheel liner near the passengers fender or install it on the passengers support brace that goes from the passengers headlight area to the center of the firewall and secure it with plastic tie bands.

The MAP sensor MUST be ABOVE the level of the throttle body .
