On the way home tonight I got into the pedal because there was no one around and after I noticed a popped a CEL I slowed down then to see if the car was running ok, and it was. So when i get to the house (which isnt that far) i plugged in the predator and i read the code and I came up with P0690 = ECM / PCM Power Relay Sense Circuit High. Has anyone gotten this before? This is my first time getting this and I would like to find out how serious this is. Thanks in advance.
