Hello all, anyone have a issue with trouble codes and warnings being displayed on a 2008 Impala but they really don't exist? I get a low oil press. warning, Engine Hot, shut AC off, etc.
But none are true! The low oil press switch was replaced. still get the code. I even disconnected the wire harness from the oil press switch and the alarm still comes on!
Appreciate the feed back. Thanks

 

Why ignore the what the code says it is. Could is be that you actually have Low Oil Pressure ? You need to test by attaching a Oil Pressure Gauge to the port where the Oil Pressure Sensor goes.

 

I will try a pressure gauge. But the car has been running like this since mid summer. If there was no oil pressure, or low oil Press, I think I would have begun
to see some issues or knocking!

Plus, these codes are all happing at the same time. But I will hook up a gauge and see what happens. Thank you.
