I have a 91 vette and i have fault coeds of 46, and 52

code 46 is the first code that appears. its (passkey II)or powersteering pressure switch.
is this a common code?

the code 52 could be many things from wht my book says. - Engine oil temp sensor circuit, low temp indicated or fuel Calpac missing or Over voltage condition or Egr Circuit fault.

How in the world do they expect a person to figure this out.

Help Please:(

How is your car running???
When did the light come on??
erace the codes and drive it until a code returns
Then you begin to trace the problem down

Oh the car runs awesome! My engine light comes on sometimes after a long drive. I know I have a VATS problem. But the other code 52 is what I am tying to fix. My other book says its the oil temp switch. I just cant seem to find it.

what t-stat do you have?? 160, stock or other?? what is your coolant temp after a long drive when the light comes on??
Your code is for oil temp low
If your coolant temp is OK I'd replace the sensor first(usually near the filter) Then proceed with diagnostics if code returns
