93corradoguy 0 Posted July 18, 2006 Is there an easy way to ground my ecu? I'm getting these crazy readings (-9 degrees Celsius) from water(blue) temp. sensor and my air intake sensor. I've replaced both of them and it's still reading the same. I was told to start by grounding my ecu and engine. I'm sure my engine is ground...now for the ecu. Any help would be appreciated.

zacon 0 Posted July 20, 2006 I'd be surprised if the ECU-casing isn't ground. Thus the easiest way to ground it would be to tape a wire from the engine to the ECU-casing. (I wouldn't recommend that as a permanent solution) You could also just measure the resistance between the ECU-casing and battery minus if you suspect the ECU isn't grounded. It shouldn't be more than a couple of ohms. Same with the engine. I can tell you that pin number 6 on the ECU-connector is common for both the sensors you are refering too. It should be brown/white.
