2007 Saturn Outlook XR V6 121,010 miles stabiltrack/traction control warning indicator posted after driving 5 miles on expressway. Shortly after, low oil pressure posted also. Chevrolet dealer service dept. says these particular indicators all post together if one detects abnormal operation. Changed oil & filter & inspected old oil for sludge/metal shavings. No contaminants found. Oil pressure normal until engine gets hot then drops to 5 psi consistently, then cam actuators start knocking. If engine cools down, warning indicators clear & engine runs fine. Service rep says likely cause oil pick up tube restricted or bad oil pump estimate @ $2000-2500 mostly labor to pull engine. Could the oil pressure switch be the culprit? Note, transmission is shifting from drive to reverse with hesitation & clunking but performs ok in drive & reverse.

The "oil pressure sensor" won't make the engine noisy... Service rep more than likely has correctly diagnosed the problem!! ... I agree with that finding and have just a little bit of knowledge about auto repair.... I stayed in a Holiday Inn Express!
