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.

Coolant fan relays


if there is power to the plug then the relays are good. chances are that the thermo sensor to the fan is faulty.
