#127 of 301 DTC code P0452
Jun 27, 2007 (3:04 pm)
I have a 1999 Cadillac Escalade with DTC Error Code P0452. This is described as Evaporative Emission System Pressure Sensor/Switch Low Input. How do I "fix" the problem. I recently had the fuel pump replaced, before the "check engine" light came on. On a recent trip when I opened the gas cap to fill, it appeared to be under a vacuum. I saw where someone recommended to replace the gas cap, what other items should I check and how?

The Edmunds Maintenance Guide has summary TSB info (sometimes the NHTSA has full text, but not too often).
If you find one in the summary list you want to read, sometimes the service writers will copy them for you to take home.

Just bought 05 ext which has about 1000k left on original gm warranty. Has anyone had problems that are common on any 05's that I should look for. Rides real nice on michelin LX tires so far only foglamps allowing water in.

#134 of 301 2007 EXT bed covers leak
Aug 24, 2007 (6:56 am)
Thet forgot to tell me that the truck bed cover panels are NOT watertight. Water gets inside whenever I wash it. Cadillac says this is how it's designed and that if stuff in the truck bed gets wet, tough. Amazing. BE WARNED
#135 of 301 flash to pass
Aug 30, 2007 (8:23 am)
I have an early 2007 escalade and had to recently get new key fobs. When they were re-programmed the flash to pass would not work during the day when the headlight switch was set to off or auto. Cadillac says that the new ones are like this and that is the way it should have been. I know of no other cars that operate like this

This was necessary because of the nature of HID headlights. Rather than use a halogen high-beam, the system retracts a shutter over the lens of the low beam pattern.
Since HID's take a few seconds to ignite and come to full brightness, it isn't feasible. Secondly, repeated ignition shortens the bulb's life quickly. You don't want to be changing these bulbs out much.. $$$.
I believe that BMW solved this problem by keeping the HID's lit all the time (angel eyes), and the flash-to-pass feature is simply the shutter opening and closing.
