Every once in awhile I check for fault codes on my 91 OBDI MJ using the ON/OF key. There have never been any, until today. I got a 12 (Battery or power to the ECM disconnected in the last 50 key cycles), 14 (MAP sensor voltage too high or low. Check circuit and sensor), 34 (Fault in cruise control circuit), and the closing 55. I'm not concerned with the 12 or even the 34 (do not have cruise), but do not understand the 14. I checked the MAP 5V supply (good), the MAP output at idle (2.1V, good), and the sensor ground point (good).
The vehicle runs fine. I ordered an new MAP anyhow and will see how it goes. Is the norm that a new MAP sensor will kill the code 14, and can the cruise control code 34 somehow be related to the MAP 14? Thanks.
