!!Need some help with a map sensor..!!
Well my wagon has been throwing a map code ever since i put in the new swap. It has an aftermakret throttle body which moved the map to the tb, instead of the fire wall. Since then it's been throwing the code 3. Well i switched the map sensor to the firewall one and now it's throwing a code 5! Any ideas on what's going on? It's really getting on my nerves. Been messing with it for a long time now, and still the same result..
Any help would be much appreciated.
ok, need to know what kind of motor for one. on your aftermarket TB, does it have a spot for the map on top? if so, thats where it needs to go. that eliminates the vacuum hose coming from the TB is all. what you need to do is borrow a vacuum pump, apply vacuum to the map sensor while monitoring the signal voltage coming from the sensor, should be between 1.0-1.5v at idle (high vacuum) to 4.0-4.5v (low vacuum) at WOT. also check power to the sensor, should be 5v. (or you could just try replacing the map with a known good one to avoid all that). if the map sensor voltage is good, and the signal voltage is good, there might be a problem with the TB? but testing the map is what i would do, cause a code 3 and a code 5 is basically the same, its a problem with the map sensor circuit. let us know what you find...

also, make sure you didnt switch the tps and map sensor connectors, very common mistake.

You can't on my car. The map wiring is seperate from the engine harness.
And it's on a semi-built LS/Vtec with a blox 68mm TB and AEBS intake manifold.

It's a stock D15, what are you talking about? Lol.
