    Geesh, finding what an engine code is can't be that difficult, on my Dots honda you stick a paper clip into the plug module and the code flashes on the dash, look up that number on google and you have the problem. Anybody know if I can do the same on my GM.

You need to put it on a computer to find what the code is such as on o2 sensor or a number of other things. once you know the codes you can fix the problem

Vehicle code scan fo Pontiac Montana


If the "check engine" or "service engine soon" light is on, then the computer has detected and stored a trouble code ( DTC) and you need an OBD II code reader. the connection should be on the drivers side under the dash on the inside of the vehicle. In some states the local auto parts store will do this for free.

2001 montana "service engine soon"


Hello and welcome to FixYa!

This warning serves as like a maintenance warning. It can just be a simple oil and filter change. Not a big deal but definitely you need to have an oil change.

Hope this helps and thank you for using FixYa! Have a good one!

2002 pontiac boneville sevice engine soon light stays om


hi what this is telling you is that you now need to get the vehicle serviced, what manufacturers do is put a certain amount of miles on the system before the next service is due, this will depend on how many miles before the next one, eg, if the manufacturer says that you have 12,000 miles between each service it will put 11,500 miles as a reminder, then when you get over the miles say 12,500 this will stay on until the service has been done and then the light is reset by the garage....hope this helps please rate and vote thanks

Service Engine soon light on - diagnostic code says o2 sensor. What is an O2 sensor and is it hard to replace


You'll need to give us the specific code, in the format P0xxx. Just saying "O2 sensor" doesn't mean anything. It could be the heater circuit, fuse, o2 sensor itself, etc. Changing an O2 sensor isn't too hard but you may not need to replace it/them.

Please report back with the code or look it up at http://www.check-engine-light.com

Service engine light comes on , p0420 code


the light can be caused by any one or combination of over 200 trouble codes, go to any kragen or Autozone parts store and ask for a trouble code test, it is free, then record the code(s) they come up with and post them back on fixya

Check engine light


the only way you can retrieve these codes is with a code reader. it's cheaper than a scan tool. problem with these is it only reads the codes and the booklet tells you what the code means but it can't clear the code and it can't change the parameters to keep the codes from coming back. do me a favor and rate this ...thanks
