Map sensor possibly bad what should it read on ohm meter i got a 31.1 reading??????????
SOURCE: need 2001 daewoo nubira map
map sensor has 3 wires a 5volt supply on terminal C, A is earth(ground), and B is signal voltage to engine ECU.
A low voltage (high vacuum) output of 1 to 2V is present at idle. A high voltage (low vacuum)
output of 4.0 to 4.8V is present at wide open throttle. The MAP sensor is also used under certain conditions to measure barometric attitude changes. The ECM uses the MAP sensor for the delivery and ignition timing changes.
