Question about Cadillac Cars & Trucks
A hard question....
why ask, because the op guide said to check it every 50k
or rumor, or? some cars btw have NONE. some engines.
so tell me why you want to find it? this tells me lots.
what model car,
most cars are on the intake manifold
some are well hidden.
there are 4 caddys which one.
there are many engines which size?
ill pick one at radom to show that anyone can do this.
online, at alldata dot com.
i pick 03 CTS
on line now... 2 engines used 1 car CTS ,usa.
i see page with 10 engine views.
ok the engine matrix of the CAD
shows 7 engines of which only 3 have EGR.
the 2.4L shows none. L4,L5, and L6
the V6/and V8s section show EGR.
so what do you have. ?

YOU NEED TO DISCONNECT THE BATTERY FOR 5-10 MINUTES FOR FAULTS TO CLEAR COMPLETELY..HAVE SEEN THIS PROBLEM BEFORE AFTER REPLACING AN EGR VALVE..IT WAS A TECH TIP FROM CHRYSLER ENGINEERING..THE EGR VALVE WAS THE PROBLEM,BUT THE PCM WOULD NOT LET THE CODES GO EVEN AFTER CLEARING THEM WITH SCAN TOOL..ALSO CHECK CONNECTIONS AT EGR CONNECTOR FOR SPREAD PINS

The EGR, or exhaust gas recirculation valve, takes inert exhaust gasses
drawn from the exhaust system and reintroduces them into the combustion
chamber through the intake manifold. This process lowers the peak
combustion temperature and helps combat the formation of Nitrous Oxide
(NOx) in the exhaust.

This link shows the location of the SCV, If your motor is different the location should be similiar. http://img510.imageshack.us/img510/5687/vacuumdiagramuh3.jpg
There's a vaccuum line that runs off the SCV to the SCV check switch.
P0442: Have you inspected the lines, charcoal cannister etc? Make sure the fuel cap is tight. The easiest way to check the system is to have someone perform a smoke test. I had a DTC on my car which indicated a EVAP problem, it turned out to be the Fuel tank evaporator Control Solenoid.

SOURCE: EGR VALVE ON 96 FORD PROBE SE
If it's a 2.0L, 5 speed (1994-7) there are two DPFE solenoids (both w/ 3 vacuum ports) near the oil filter, which control the EGR valve. They are discontinued and impossible to find except on junked cars. (FORD #'s K5T44093-4)
I have to junk my 1996 Probe if I don't find them - Missouri emissions.
