Hey everyone,

so I just very recently got this car because it was having "electrical problems."

The previous owner said the car would give error codes P1122 (throttle sensor low voltage) and P1560 (System Voltage).

I am kind of new to working on cars and am curious on where i should start in order to fix this issue. Any help is appreciated.

Thanks!

Have you had the battery and alternator tested?

 

+1 on the battery. If you don't know the history replace it. The next thing is to check all of the power connections from the battery and the main ground points. They cause a lot of electrical gremlins.
Start with the bulkhead connector in the engine bay. Take it apart and clean it to bright and shiny and reassemble it. Make sure the battery connections are clean and tight. There is a ground strap from the engine to the chassis behind the passenger side front tire attached along the frame. Clean and tighten the connections and make sure the strap is in good condition.
Clear the codes and run it thru the drive cycles and see if they come back.
