Inspection Time for my 1996 850 Volvo, but a problem here......
I took it to my mechanic and he turned off my engine light, and he told me I have to drive alot, so when he sets the monitor in between my front seats, there are some codes that are not done yet, I have two codes left to be done. I have been doing alot of driving and my mechanic has turned off the check engine light twice, and i need to get my inspection asap, please help me.

the computer meters fuel based on a signal from the coolant temperature sensor. The check engine light sometimes does not come on when the sensor fails.If the sensor is causing your problem you will have a strong odor of gasoline when the car starts,It will be slow to start the first time, turn it off and it will start right up. lol
You don't disconnect anything on today's
vehicles, even with the key on
Put in a new battery,start the car, warm it up
& drive it for awhile & maybe you will get lucky
& it will complete some of the drive cycles & run some
monitors ,you know nothing about & it will be fine
If not, your mechanic friend should be about to stop
by with the bosses scan tool & help you out
He can't hit a switch and turn on the Check Engine Light, however there are several dozen ways a shoddy mechanic can cause that Light to come on.
Two things you can do is:
1. Disconnect the negative side of the battery and wait about 30-minutes before reconnecting. Check to see if that Light comes back. If not great! If it does:
2. Find out why the Check Engine Light is on. There should be a code that the computer has set. Take it to Autozone or other auto parts stores, where they can hook your vehicle up (for free) to a DRB Scan Tool to eloborate or extrapolate what the Code(s) are.
The real question is if the work the mechanic did caused this. Have their work checked.

try over riding the starter relay on the fender ,it has one there right?. dont go to a mechanic yet. the engine aint seized. if it doesnt have this relay then i would get the alternator tested. if you want to test it yourself it can be costly for the right equip. autozone usually tests for free. i dont know were you live so if theres not an autozone. let me know if you cant get it tested.
I have just had a similar problem with my Nissan Cefiro (Maxima)2000 The Fault light came on and it was the front cam sensor. The part cost $183NZ ($##@) and took a few minutes to replace. Fault light went out...all ok. The told me it was a timing problem too and maybe the chains needed changing ($2500NZ) for that. Mine has the Variable Timing System (neo Engine) which is what yours may also have. I would be changing the sensor first as that is probably the problem. Mine has only done 44,000K's (ex Japan so always suspect) and with yours only 59000 I doubt there is anything wrong with the timing chain. Hope this helps
