which wires which
later 2bar map sensor.
does anyone know from left to right which wires which please :notworthy |
Give me a model-year and I'll try and dig out the info :)
|
thnks should have posted up have found it now
MY92-96 MAP sensor Wiring Red = +12V White = Sensor Green = Gnd MY97-00 MAP sensor Looking at connector with pressure pipe facing down Left = +12v Center = Signal Right = Gnd Pin Numbers Wire colours: 1 = Blue 2 = Yellow-Black 3 = Red |
Cool - glad you found it ok :)

cheers , hopefull all probs solved now, 02 was firked and was running silly rich, but keep killing map sensors but now know that 16.6psi is 1.15bar so i was demanding to much from the 93 1bar map sensor, does that sound right
|
I'm surprised that a 2 bar MAP sensor was killed by such a small amount over...usually they are rated to at least 50% over-pressure. But I don't have specific experience of this so it could be the case.
More likely that a sensor is killed by dodgy wiring, in my experience. |
might be wrong but i was told the pre 95 map sensor is +1bar -1bar so 1.15 over was killing them, anyhows the after market 3bar is coming off for peace of mind as 5volts devided by 2bar = 2.5volts per bar and 5volts devided by 3.0bar = 1.666 volts per bar so i figured the voltages are wrong anyhows

You can't change a MAP sensor for a different range unless the ecu is remapped to suit.
To be pedantic, a MAP sensor measures absolute pressure (MAP=Manifold Absolute Pressure) - so 1 bar of boost is 2 bar absolute since atmospheric pressure is 1 bar. So 1.15 bar boost is 2.15 bar absolute, which is just a few percent over range for a 2 bar sensor: which would not kill it IMHO. |
