Throwing Codes ...
I don't know if my car has the Pre-Race Jitters or what, but he's throwing two different codes.
1. Code 25 - High temperature at manifold air temperature sensor OR Vacuum switching valve circuit open or shorted to ground OR High voltage at ATS sensor
2. Code 54 - Low voltage at fuel pump OR Low voltage at Fuel pump relay OR Output failure at quad driver module
Is there any way that these two are related to each other? I've never had of either of these before, so I need some help. Are these serious, as in don't take your car to the track Sunday or are they 'no biggie'.
Please someone respond ASAP!

Have you tried to reset your computer?? Is the car running different? Not sure what to say, just a couple of thoughts.

The car seems to be running just fine. I will try to restart the computer, and see if that helps.
Thanks.
