Pontiac: Code 63

Last week I got code 41, so I pulled the cam sensor out to see if the
magnet was shot, but couldn't see it through the hole in the timing
cover, so I put the cam sensor back in. Code 41 cleared.

Today I get code 63. SES Light was on for about 4 hours. The book that
came with the code scanner indicates code 63 to be

1. Manifold Absolute Pressure ( MAP ) sensor - signal voltage is high.

or

2. Small EGR failure,

or

3. Right Oxygen sensor failure ( dual sensor engines ),

or

4. Cruise Control system problem.

The Pontiac Service Manual says code 63 is EGR related. I see no mention
made anywhere in the book about a Manifold Absolute Pressure sensor (
MAP ) so I assume I don't have a MAP sensor on my car. I don't have dual
Oxygen sensors.
The EGR Valve is the original still.

Later I went for a drive. The car starts fine, runs, idles and
accelerates fine. I tried the Cruise Control and it set & held for the
short distance it was on around town driving under 45 mph.. The SES
Light went out after turning the cruise on & off a few times .

Tuesday, I had removed the turnsignal lever from the column to see how
it came out ( a poster inquired about how to remove one a few days ago
so I thought I'd try it on mine ).

I also disconnected the wires connected to the lever.

I wonder if code 63 setting had anything to do with my removing the
turnsignal lever, which houses the Cruise Control buttons?

Going to test the EGR valve tomorrow. More than likely that is the
problem. I guess it got to give trouble sometime, afterall its been
working a looooong time.
