i have a 1993 honda civic d16z6 and i have absolutley no power to my map sensor......any ideas as to what could be causing this? need info asap car runs like ****.

 

need to get a pinout for the ecu check for power from there .. if there is power coming from the ecu then its a wiring issue if not prolly gonna be internal in the ecu .. more than likely its a wire issue .. im sure someone here has a link to a pinout for you ..

 

More information is needed. Is there a MAP sensor code? What wire are you testing for voltage and how are you doing the test?

 

How are you testing it? If you are sure there is no MAP sensor power when the car is in ON(II) then trace the wire back, it is either shorted or broken. I had the same problem happen to my Map except it was on the Ground. So I ran a new ground wire for it and its been fine ever since.

 

no power to the map would cause low rpm sputtering? running rich? and really bad gas mileage correct?

 

yes

 

 

ok so heres a new scenario ive never seen before.....when i take the fuse out for the ecu and put it back in start the car and drive it it runs perfect....but next start up it runs like **** again???? replaced ecu and still same thing happens......any ideas?

 

How can anyone help you if you refuse to answer any questions? Please stop posting until you are ready to reply point-by-point to questions.

 

well wouldnt my last post state the fact that i figured the ****ing thing out? but im confused as to why it is doing that......hmmm id say that its more then just a map sensor problem...wouldnt you?

 

No. Almost nothing important can be inferred or concluded from your information-less posts.
