#1107 of 1216 Thick White Smoke [nikia_mm] by nikia_mm Jul 07, 2009 (7:37 pm)
Replying to: nikia_mm (Jul 05, 2009 3:37 pm) Any suggestions would be greatly appreciated. My 97 Catera is producing an enormous amount of thick white smoke from the tail pipe, prior to this it had been smoking from under the hood for the first 5-10mins upon driving but once on the expressway it would cease, also I could smell oil burning. We checked the oil and the level is fine, coolant level is fine and there is no visible water/oil mixture on the oil stick. Any suggestions to what this might be

Replying to: ledc101 (Jul 08, 2009 6:44 am) Any "U" code means there is a communication problem. This is the ability of all the modules of the vehicle to communicate with each other. Any time you get a "U" code stored, it is necessary to connect a scan tool capable of looking at every module on the vehicle to determine where the problem is. If you don't have a capable scan tool, I would suggest a top notch repair facility or even your Cadillac dealership. Actually, once you diagnose the cause of the "U" code, there is a good chance it may clear up all your other problems. Good luck.

Replying to: calicago (Jul 07, 2009 10:03 am) I'm not really exactly sure what you're saying. When you say "cps", I assume you're referring to the Crankshaft Position Sensor which is actually called a "CKP", right? When and if you installed a new CKP, are you sure the wiring is snug and tight with no breaks in the wiring and generally it is better to reroute the harness and not put it back the same way as the factory installation. When I say reroute it, the main thing is to be sure that it doesn't come into contact with any of the exhaust manifold. If no signal is getting to the CKP, it doesn't know that the engine is cranking and will not kick in the fuel pump which would mean no fuel. Also, have you changed out the in-line fuel filter? Might try that next. Replies to this message: calicago (Jul 08, 2009 8:50 pm)

Replying to: ledc101 (Jul 08, 2009 6:44 am) This code (U2108) is a communications error with the ABS module. This goes hand-in-hand with the TC and ABS lights and code P0500. The VSS is wired to the ABS first, then carries over to the ECU and speedometer. I found this out the hard way with a buddy's Catera. When the ABS module has communications errors, the speedometer loses signal from the Vehicle Speed Sensor (VSS).   There is hope. We called www.bba-reman.com, and they were able to fix the ABS controller. This is the black plastic box on the ABS module mounted down on the car's frame rail on the driver's side. They have DIY instructions on their website to remove the controller without removing the valve assembly and motor. This means you don't need to remove any brake lines or crack any of the lines open. Mail off the controller, and they rebuild it, test it, and warranty the work for a year, and send it back. According to them, you can still drive the car without the module. They charged us $169, which included return postage. This fixed the ABS, TC and CEL lights.   For the coolant light, check the coolant level in the reservoir. If it is fine, then the sensor may be bad. It is mounted to the bottom of the reservoir. Replies to this message: ledc101 (Jul 09, 2009 9:01 pm)

Replying to: dgaw (Jul 11, 2009 2:18 pm) The 400 series codes means that your O2 sensor is sending a message of a bad converter or maybe the O2 sensor is bad. This could be a number of things and could be ruining your converter if not addressed.   The most common cause is contamination of the catalyst because the engine is burning oil or leaking coolant internally (leaky head gasket or a crack in a combustion chamber or cylinder). Converters can also be damaged if they overheat due to ignition misfiring that allows unburned fuel to pass through into the exhaust (check for a fouled spark plug or bad plug wire). The same thing can happen if the engine has a bad exhaust valve that leaks compression into the exhaust (check compression). Replies to this message: dgaw (Jul 12, 2009 2:46 pm)
