I have a 2001 w/ 150,000 miles the other day the Service Vehicle Soon Light comes up at the same place as the change oil soon light comes on. Both fans come on and the heater blows hot when on. Anyone got any feed back on this issue.:banghead:

A stuck open thermostat can cause it to run cooler then it should and illuminate the SES light.

Does the heater blow as hot now as it has in the past?
If your thermostat is stuck open, the engine won't come up
to full operating temp. If the engine is not up to temp, then
the heater will blow luke warm air instead of hot.
If the fans are coming on, then it sounds like the engine is
Were you running the defrost or AC when you noticed the
When the defrost or AC is on, the fans turn on automatically
when the AC compressor runs.
Does the gauge even register any temperature at all?
You might just have a bad gauge, sending unit, or just a

I think its a loose wire or a bad fuse. Because when I turned on the car this morning the Service engine soon light was on.I get to work stay for a couple hours. I leave work it is on still get to my first stop leave turn on the car the gage is working and its been working ever since yesterday afternoon. This car is starting to do crazy things.
When It was not working I tried turning the heater on it blew hot. Also the fans would come on after a while with the air off and after I shut the car off. It was not reading any Tempature on the gage I turn the car on and it would move very little and just stay there would not move at all no matter what I did to make the engine hot.

You might want to have that checked out.
You may have a corroded wiring connector someplace causing a bad ground.

I've recently seen the same problem on my Aztek. I just returned from a 700 mile trip. On the last tank of gas, the temperature gage needle swung off the scale (cold), and the DIC display lit up with Service Vehicle Soon. I finished the trip (about 250 miles), and the gage did not work for the remainder of the trip.
I had seen the gage do this on a previous trip, but after a while (half an hour?), the needle swung back up to the normal range, and the SVS light went out.
This seems to me to be an electrical problem, like a loose connection, or possibly a short. For this last incident, it started when it started to rain.
