my oil pressure gauge went to 0 then every now and again it will read normal. i got P0523 code (engine oil pressure sensor switch high voltage) im assuming sensor needs to be replaced? how hard is that?

also a code P1693 (turbo charge controll circuit malfuntion) how seriuos is that.

this how they showed up P 0523
P ECU
P 1693
its a 2001 dodge cummins any insight would be great

 

the turbo code dont fret the oil sending unit needs to be replaced it easy to replace

 

cool thanks a bunch

 

P1693 is just a companion code meaning that a code has been set in the one of the 2 computers. Its a very common code to find and really means nothing. Take a look at your wiring for the sender and make sure its not damaged and if not, then replace the sender.
