The Engine Control Module (ECM) detected no change in MAP sensor voltage. Possible causes - MAP Sensor harness is open or shorted - MAP Sensor circuit poor electrical connection - Faulty MAP Sensor Since you already replaced the sensor, it's probably an issue with your wiring.

Can that cause the engine to idle real rough? And loss of power? Also yesterday when I replaced the MAP sensor I drove the 100 miles so the computer can reset it self for the check engine light went off. But it was still running rough? After that the check engine light was blinking on and off than would stay. So we went back to Advance Auto to have it hooked back up and it just came up that the MAP sensor was no good. So they replaced it with another one. Just before we got home the car died. and had to get it towed. It ran worse after we hooked the second MAP sensor up. It also stated that there is a missfire with cylinder 3?
