2003 Chevy Cavalier Mileage = 62,344 Engine size = 2.2 dash lights = check vehicle light

Question = Hello. My 2003 chevy cavalier has the service vehicle light on. A wrench with the
word service on it. Also the odometer does not show any number, it says ERROR. Any help
would be great, thank.
Answer:
Thanks for the tip/donation.
These symptoms you are describing sound like a problem in the BCM (Body Control Module)
The bcm sends the odometer reading to the dash cluster. Since it says 'error', the dash is not  
receiving the correct data.

The service vehicle light is on because of this problem. To be sure,  
you need to have the BCM scanned for codes. If you find B1000, then the BCM will need to be  
replaced. I will send you instructions on how to do this if you are going to do it yourself. Once  
again, thanks for tip/donation!
Answer:
If you are sure the car is not overheating and causing the temperature gauge to go into the
red, there are a few other things you can check. It says you've replace the temperature
sensor, which is a good start, but you also need to check the connector and wiring at the
sensor as well.

You could have a bad terminal, or corrosion causing lack of signal to the gauge. You could
also have a PCM that is bad and not allowing the signal to go through to the gauge on the
dash. If all of that checks ok, then you probably need to have the gauge replaced. This would
involve removing the instrument cluster and either sending it out for repair or buying a new
one.

You would most likely have to go to a dealership to have that done.
