I recently bought a used link. I'm told it came out of a working car. Its going into my Locost which has a 94 miata engine and wiring harness in it.
So i moved the wire that needed to be moved. and plugged it in. I can get everything to boot fine but when I go to check the MAP sensor reading it says 8kpa. The instructions say it should be around 100 at sea level. Ive checked- the solder joints on the ecu, the solder joints on the map sensor. the integrity and continuity of the wiring to the map I get 5.5volts on pin 2 and 3 of the actual map sensor. pin 1 has 2.2volts at idle. My first guess would be a wiring issue but for the life of me I cant find the culprit. Ive tried adding grounds to the ecu and battery and still seeing 8kpa Another problem I am finding is my air temp sensor is always reading 100. Even if i plug it directly into the ecu (via a pair of prongs). I get continuity and everything looks fine. Please help! I'm absolutely stumped! ~J
