Have you checked that your battery is properly hooked up and charged? I got a bunch of weird code last year that resulted from my terminal bolt being loose. The intermittent voltage caused a lot of items to code out despite being perfectly fine.Can anyone help with troubleshooting this code? P0523 engine oil pressure sensor circuit high. Is it normally just a sensor? Anyone have pin out to test the wiring at the connector? Everything looks good. Sensor is good and tight. Connector and wiring is good and tight. Code changes when disconnected to a P0522. Engine will also stay running won’t shut off when disconnected. TIA! And any specs for testing would be greatly appreciated!
