I've been a professional mechanic/technican since the late '70s and now I own my shop and specialize in electronics and computer control diagnostics on American and most Asian vehicles. I supplement my own training and even my shop by traveling around the country as a continuing educational instructor. My image is a compression test on a Volvo S40 using a pressure transducer and it shows the exhaust camshaft incorrectly over advanced. Check out my blog, "Autotechtitude" at http://johng673.blogspot.com/ In my blog I'll take you inside the world of today's diagnostic technician and you will see the tools, strategies, triumphs, and of course some of the lessons that are learned the hard way that every technician experiences.

Question Answered: 

It should slow down, but not necessarily stall. You should achieve a minimum idle speed approx 600rpm in drive with that disconnected.

Question Answered: 

The code means that the camshaft position sensor signal and the crankshaft position sensor sinals are not in sync with each other where the PCM expects them to be. The potential causes are the timing belt (if used ) could be off a tooth, the camshaft actuator could be stuck, the camshaft actuator oil control valve could be faulty, and/or passages inside the engine could be sludged.

Question Answered: 

This needs to be diagnosed, and that requires some of the steps be done with a scan tool, preferrably the techII.

Question Answered: 

It is normal for an engine to use oil. You simply have to be in the habit of checking and adding as required and it not only won't hurt anything, the additional additive package with the fresh oil added between changes will actually improve your engine's life. Oil useage is not considered excessive until it results in driveability issues such as fouled spark plugs, and that usually doesn't become an issue until the useage gets to be more than a quart in 500 miles.

Question Answered: 

Was there any activation of the ABS just before coming to a stop before the lights finally came on? The question about whether it is safe to drive or not cannot truly be answered in a forum like this. Essentially one could easily guess either way but no-one really knows until they first check the brake fluid levels and then see what the pedal feels like and then if it feels safe drive it and see what the car is doing while pulling codes and monitoring system data.

Question Answered: 

You have posted multiple times. Here is the answer you need. When the system is tested the technician will need to make sure that the pressure equalizes when the system is shut off. We have been finding restricted receiver driers caused by coking of the oil due to poor airflow in the condenser.

Question Answered: 

We need to attach a scan tool and take a look to see if all of the inputs and commands are taking place between the shifter console, the transmission and the front control module. We can handle this if you still need help.
