Ok, so i bought this 2006 Honda Civic Ex coupe automatic on Facebook about 2 months ago. Whenever I bought it the transmission was acting up. Well I fount 2 sensors unplugged from it and plugged them in. Now that fixed the transmission, but the speedometer, tachometer, and temp gauge shut off directly after it was plugged up. And the OBD port doesn't read a car when its plugged up, but the port has power. I know one sensor that was unplugged was the speed sensor, the shortest one closest to the driver side of the car on the transmission and the one directly below it. I need to know what to do to fix the gauges I don't mind the OBD port being out.
