Question Asked: P1295 - Bad MAPS sensor?
September 13, 2010, 08:43 AM
I have a 2007 Sedona that went into TAC Power limited mode. The code from Advanced Auto shows P1295.
The dealer recommended changing the Throttle body sensor, but that did not fix it. The MAPS sensor is also on the list for P1295. When I do the factory test of 5v dc accross the sensor and read the feedback, it gives me 3.8 volts at standard pressure. My guess is it should be closer to zero. Any HELP!!
Additional reading indicates that the MAP sensor is an ABSOLUTE sensor which means that it uses zero pressure as its reference. Standard Temperature and pressure happens to be very close to 4 volts. The MAP might be ok. Any thoughts?
Is anyone out there?
