I have a 98 gt coupe 3800 and I'm getting a p0107 and also my gas gauge and coolant temp gauge is off along with an intermittent srs light which leads me to believe I'm having a ground issuse.
Question is where would I find said grounds?
 


I pulled the code at work cleared it and it was back before I even fired the engine is what led me to believe that it could possibly be a ground causing the low voltage code....

that being said I'm a body and frame tech by trade no a driveability tech so I appreciate any input. I will pull the cover and check my vac lines and see where it leads me.
 
Well I cleaned the grounds fixed a vacuum leak that I found and cleared the code BUT after driving awhile I parked it for an hour or so and as soon as I fired it the SES was back on and I pulled 2 codes this time a P0107 and IIRC P1107 a low input and intermittent low voltage code. I checked the voltage at the sensor about a half dozen times after that and it was within tolerance around 4.98 volts each time any other ideas and what are the chances the sensor it's self is bad?
