Throwing PO107 Map Sensor voltage too low

***Civicn33b*** · 04-18-2008, 06:44 PM

I just loaded a pre-tuned map on and im throwing a CEL. Scangauge says its PO107 which I looked up and says "map sensor voltage too low" is this dangerous? im kind of confused?

Still having the messed up issues with your interior electronics? Could be related. Floating ground = less voltage differential = no go electronics. I'm not saying that is the likely cause.

The ECM info sticky says 1-3V is the operating range of the MAP signal. Idling is 1V. Not hard to lose 1V due to a bad ground.

That'd be the first thing I'd check though I can't confidently say since I can't see your car if my a$$ is sitting in this chair lol

you got any pics of your engine bay near the battery and the ecm, showing how you wired your stuff up?
