Hey yall. I’ve got a Honda Accord from 03 that’s running really rich. I scanned the car with a rented scan tool that came back with p0108, which shows a map sensor failure or a wiring problem in the map sensor harness. I replaced the map sensor, tested the wires for continuity to ground and for voltage KOEO. Just for fun I cleaned the egr valve and the throttle body, which is when I noticed that the throttle body wasn’t opening at all except when I first turn the ignition on and then it closes immediately. I thought that it might be a throttle position sensor but this car ain’t got one. I also took the map sensor back to the auto parts store and got another one just in case it was bad and the newest one still didn’t fix the problem. I’m a bit stumped here.
