My map sensor is malfunctioning. Its weird tho it only malfunctions SOMETIMES, like sometiems i drive my car no problems, other times ill feel this slight hesitatoin while driving for a split second then my CEL comes on and when i idle its eratic and sometimes if i go from say slowin down in 2nd and put the clutch in, the rpms will work their way down an then the car will just shut off completly. Im not sure what part of the sensor is fautly i hvae a haynes manual and it said to check the voltages and the Signal wire seems to be the problem should have 5volts when in the on position and grounded but it only has 3.53?? I nkow i can replace the sensor that sits on top of the TB but i dont think that its the problem i think its the wires, and they seem to run into the engine harness, so what do i do to try and fix this??, 95 dx, d15b7 by the way, thanks.

Clifs, Map sensor messes up SOMETIMES, erradic idol, car shuts off when put in N or clutch in and slight hesitation right before cel comes on, how to fix?

 

bump, i think i fixed it, i had put a new TB on my car a few months ago off an integra and i THINK i may have left the map sensor from the teg on the TB, it ran fine for a while but maybe it was faulty i switched them and so far so good, just to be sure, anyone with a d15b7 engine care to take a look at the #'s on the top of their map sensor for me cuz im honestly not sure which i had on there and which i just put on thanks

 

ok sombodys gotta help me out, i had the good sensor in, but im still getting a cel after i drive around for a few, idle becomes erradic and somtimes it fights to even stay on, idle will float from about 200-500, wtf is wrong, i checked the votage from the plug, not 5 volts like it should be, followd the wire back some checked it not five volts, do i have to get a new harness?? or what, im not gettin the correct voltage to the sensor and the pressure reading is trasmitted to the ecu in a voltage #, what can i do? the wires run to the major harness plug on the left shock tower if your lookin at the engine from in front of the car

 

u might have switch the plugs around like the tps and map sensor, it might be crossed, im not sure, but some1 can correct me. the tps and map sensor plugs are identical which u might crossed up

 

no dont think that i switched them, nebody else??

 

final bump, guess ill figure it out eventually

 

bumps yo..i have the same problem.and cant fix it either..
