Was your theft light across the radio displayed? I also have my traction control light staying on with this problem too.Could you get you car in gear? I can not get my car out of park! I also can not get the keys out of the ignition too. After you fixed the crank shaft sensor, did you still have any more theft problem,warning etc?how much was this part, and how much was the labor? did you have it fixed at a Cadillac dealer? Sorry for asking so many questions, but I am so very frustrated!!!! Thanks so much.
Re: did the crank shaft sensor fix this permanently?
I have the same problem with my car??? I can't get my car out of park my check engine light, brake light, ABS and TC light are on. I just brought it to the cadillac dealership and they wanna charge me $1500 dollars to fix it. The service guy sayed I have to replace the PCM Module so it could not get stuck in park and the thermostate. This is crazy we are haveing the same problem??? I didn't get it fix there i'm going to look around because i'm a girl so I feel they are trying to pull a fast one on me...

Are you asking why both lights come on at the same time to indicate that those functions are not operational? That is because traction control uses the ABS sensors to operate. If one (or more) of the sensors are bad/not reporting properly, it shuts off both ABS and Traction Control. If you went over a bump or other irregular surface, that could confuse the system and set a fault that could be reset when you restart the car. If it is a more permanent failure where the warning lights stay on after the car is restarted, someone will need to perform a diagnostic procedure to find the fault.
yeh most parts store guys are **** and would rather guess then say they dont know. if you had a problem with your crankshaft your motor wouldnt be running at all... im going to have to guess (dont have enough info no to) but im willing to bet the code was for your crank position sensor
its either sensor gone or the toothed gear on the drive shaft that the sensor picks up off of ,what wheel is causing the problem i have no idea but a test with automotive multi meter will soon locate the fault
The 420 code means you need the catalytic converter replaced. The TCS means Traction Control System. The green key is the theft system. Both lights MAY have nothing to do with the car shutting off Sometimes those lights will display when something elese makes the car stall. Perhaps a faulty crank sensor or the cat is so clogged its stalling out the car.
Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on.
You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.
Cheapest option would be to have the fault code read by a dealer or specialist. Its likely to be a wheel speed sensor but its finding which one that's the problem. You could disconnect each one and take an ohms reading across the connections. They should all be the same or there abouts. Change the one thats not. If your lucky the light may extinguish. If not the fault will need to be cleared using diagnostic equipment.
This has been happening to my car as well. It typically happens when your oxygen sensors start to wear out. Mine does it once in a while and I have the local auto store reset it. Go to your nearest auto store and have them tell you what code it is and ask them to reset the OBD so the light goes out. If the light comes on right away and the code has to do with your oxygen sensors, have them replaced. There are three, two are easy to replace, one takes some effort as it is in a tough to get to spot. The dealer will charge you a fortune to replace them so do it yourself or through a local mechanic. It is a very simple task other then the access.
If you disconnect the battery to reset the engine light, make sure you have the code to reset the anti theft on the radio, otherwise your radio will not work
