Check voltage between pins 1 and 4 with the key on and engine not running. You should have 4 to 5 volts. With then engine idling, it should drop to 1.5 to 2.1 volts. Test PCM terminal 36 for same results. If different, check wiring/connectors. Test for MAP sensor ground at terminal 1 and PCM terminal 43 Test supply voltage at sensor terminals 3 and 1. It should be 4.5 to 5.5 volts and the same at PCM terminal 61 If all test good, MAP sensor is bad, if not, fix wiring harness.

1996 Grand Cherokee 6 cyc Will not idle when started cold Runs normally when warmed up Is it a bad sensor?
I took the vehicle to the dealer service department. It turns out the vehicle battery was not providing the correct voltage. Once the battery was replaced, vehicle is running properly again. In the future I will check battery condition / voltage first.
