Where is the MAP sensor located on a 1989 Cadillac Deville?

the MAP sensor is located near the top of the engine, and is on the passenger side of the engine compartment, near the A/C Accumulator (the large silver cylinder). The MAP sensor is a little black square, and underneath it there is a green connector and very small vacuum line.

MAP sensor is open E32 on an 1986 Cadillac Deville. How do I fix this problem? Thanks in advance

The most likely cause is a bad sensor, tho there is a small chance of a computer or wiring problem. Check the connector at the sensor, if it's not damaged/corroded I would replace the sensor. You can probably find a used one from a junkyard or on ebay pretty cheap.

If you need further help, I’m available over the phone at
