Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello and good evening. No there are no codes other than possible an oil pressure sensor code. The correct way to verify this is to remove the oil pressure sending unit and install a mechanical gauge to verify if oil pressure is truly low. If oil pressure is ok, on the mechanical gauge, then you have a faulty sending unit and nothing more. Definitely pursue having the oil pressure checked with a mechanical gauge before installing an engine.
