1996 Cadillac Deville 4.6 L V8.
Warning lights = Service soon.
P0741,P1660, P1406.
This is a nice well kept car..but on a recent trip, lights came on
including service transmission soon across the center. I turned
around and returned home after 49 minutes in. Just got the codes
from a Autozone center. Common on all three reads is open or short
circuit possible..also air conditioner not blowing cold since.I enjoy
fixing myself so any help is GREATLY appreciated.
Answer: Code P0741 is for the torque clutch (TCC) stuck off. There is
a bulletin for this. Probable problem in the valve body of the
transmission. Either worn seals or groove on the drive sprocket, or
the trans is slipping and needs to be overhauled. Either way the
trans. needs to come out of the car.
Code P1660 is a cooling fan circuit problem. Check fuses. Check for
power and ground at fan(s). Fans not working may be the cause of
the A/C not blowing cold.
P1406 is an EGR pintle position problem. Probably a stuck valve from
carbon buildup, or faulty EGR Valve.
2003 Cadillac CTS
Engine size = v8
Warning lights = engine light/ ts light
Question: I own a Cadillac CTS 2003..But when im accelerating around 40 to 70 mph my car
info screen will display something about engine speed and a TS icon will appear on the dash
board when i press the gas nothing happens my cars slowly decreases speed and i have to
turn the car off and then on to get it back to normal what can be the problem?
Answer: This seems to be a common problem with the older
CTS models. Usually the throttle body is the cause and will
need to be replaced. A code will usually be stored in the
computer that tells the technician the area of trouble.
Sometimes there is a wiring problem, or even a computer
problem. This type of driveability issue is severe and needs
to be properly diagnosed at a Cadillac dealership. Don't rely
on the corner shop to be able to fix this problem. You're
looking at $500+ if the throttle body needs replaced, and
possibly more if there is faulty wiring or a bad PCM.
