It's the 02 sensor heater circuit, bank1 #2 sensor, that's the one down by the cat converter. Have a new one put in.

How to change timing chain cover on cts 3.2 2003 cadilac


Well I assume that by now, 24 days later you probably have the timing cover changed, but if you don't here's a link, scroll about halfway down to get to the pictures. There's a few hours of work and as long as you've gone as far as to tear the whole front of the motor off the car, you may as well change the timing assembly and water pump. I had the shop change mine, it cost me $700.00 but it was worth it. here you go:

I have a problem with my 2003 cadillac cts code po141 i have replaced the o2 sensor on the passenger side before the cat but i still have the same problem


You do realize you have 4 o2 sensors on the vehicle? Obtaining a reading from its computer (failure code) will not tell you exactly which sensor is faulty. In fact, no device currently that I know of will give you an error code to exactly which o2 sensor is at fault. You may have replaced a good sensor with a new sensor and hopefully you didn't throw the old sensor out. I would put the old sensor back in and start performing the process of elimination method with the known, new sensor. Currently, you are 25% there (2 banks, 2 o2's per bank).

WHERE IS THE CRANK SHAFT SENSOR LOCATED ON A 2003 cts cadilac


The sensor itself is located under the car right behind the oil filter. It is connected on top of the motor right by the fire wall. You will need an E8 torx socket to get it out but it's a very easy replacement.

The black plastic grille around the fog lamp can be removed without tools. If you look through the slats, you'll see 5 or 6 "clips" that can be GENTLY released with your finger. Once the grille is out (which is about 4 inches high by about 14 inches long), you'll see that the fog lamp assembly can be removed with 3 screws. Simpler than you probably thought!
