first of feel free to move this topic where it belongs. Im sorry im fairly new and learning my way around this website. I have a electrical issue. I believe i have a short somewhere , but im no electrician. I would like to know how to test the MAP sensor, crank shaft sensor, cam shaft sensor, Knock sensor, cooling temp sensor. ASD and fuel relay. i have searched and searched and have only found how to test TPS and ignition coil. I have tested the wires coming out of the ECU to every connector pigtail. I do have signal running thru the wires, thats y my last resort is checking each individual sensor. Please someone help me.
