The oil pressure "gauge" is a mechanical on/off indicator. Either replace the pressure switch (which fail frequently) or hook up a real pressure gauge to perform a real test of your engine's oil pressure.

Also, change your oil and make darned sure it's 5W20 that goes in there. Other weight oils will screw up the VCT solenoid's function and cause camshaft timing problems.

Post your exact fault codes. It's pretty common for non-technical people to jump to wrong and very expensive conclusions.
