SOURCE: trunk will not open with button
There should be a yellow lever inside the trunk near the back seat that you can pull. You will need to lower the back of the back seat, and stick your head in there and look up. Pull the yellow emergency lever and the trunk should open. It is mandatory to have one in case a child accidently locks themselves in the trunk. Once you get the trunk open, make sure the valet switch near the trunk latch didn't inadvertently get depressed. It should be either on the decklid on the latch or in the trunk itself below or next to the latch reciever. it should be a slide type switch that you can lift up or press down. Also make sure the trunk lock out button inside the glove box didn't accidently get pressed. Hope this helps

First off, make sure that the gas cap is tightened beyond three clicks. If it is and has been then there are many things that could be causing the light to come on. But let me start by assuring you that it is not something that requires immediate attention. The sole purpose of the service engine light is to detect malfunctions of emissions related components. If the gas cap isn't tight, the computer system detects an incorrect amount of pressure inside the tank due to vapor leaking out of the filler neck. If the cap is tightened after a period of time the computer detects the right pressure and the light will go off. However, on QX4's the most common cause of the light is oxygen sensors, or cam and crank position sensors, and finally intake valve timing control sensors or solenoids. O2 sensors measure the amount of oxygen in the exhaust gas. Normally I have seen that in damp and wet conditions these sensors are more likely to intermittenly give false readings. That being said, although the SES light is not an emergency situation, it will need to be addressed at some point, as the Engine control module takes the readings from these various sensors and automatically adjusts things like idle control, and air fuel mixture ratio, and eventually will to some point affect the performance of the vehicle. I have seen folks drive 100K miles with a service engine light on, so if you don't want to spend a 200 or so dollars right away, I would take the car to autozone, have the codes retrieved, and report back to this forum, at that point I would be able to advise you a little further. But more than likely you could continue driving the car without any driveablility issues.

This link shows the location of the SCV, If your motor is different the location should be similiar. http://img510.imageshack.us/img510/5687/vacuumdiagramuh3.jpg
There's a vaccuum line that runs off the SCV to the SCV check switch.
P0442: Have you inspected the lines, charcoal cannister etc? Make sure the fuel cap is tight. The easiest way to check the system is to have someone perform a smoke test. I had a DTC on my car which indicated a EVAP problem, it turned out to be the Fuel tank evaporator Control Solenoid.
