Question about Cars & Trucks

My 2000 Chevy prism check engine light came on after an oil change.. I disconnected the battery and reconnected it and it went away but I'm concerned it will pop back up. The car has 188k miles on it.

SOURCE: p1684 dtc code on 2001 dodge grand caravan sport.

Yah code 1684, it just tells you that battery/computer has been disconnected within last 50 starts. If it doesn't drive you nuts, give it some time, you'll be suprised how quick 50 starts will go by & light should go out

SOURCE: 2000 Cavalier catalytic converter was stolen/check engine light

The check engine light is probably indicating a catalytic converter malfunction the Oxygen sensor that is located after the cat tells the computer if the cat is functioning properly it is possible the wire has been broken or damaged. To see if the cat is there jack up the car and look under the passenger and driver area of the car follow the exhaust pipe from the front back the first thing the pipe comes to should be the cat it looks like a muffler with a wire going to a sensor after toward the back side of it, I doubt they never installed one but I guess it is possible.

your car needs to be diagnosed with an obd2 scanner to determine what is causing the problem. take it

to an autozone autoparts store, they will diagnose it free of charge, give you a print out on whats wrong,

and may even carry the parts you need, once the problem is corrected they can reset your check

engine light with the obd2 scanner. or if you replace what ever it needs you can do a reset by

disconnecting the negative side of the battery wait 30 seconds and then reconnect it.

1998 Chevy Lumina has check Engine light on and code says egr valve which has been replaced now what

Check engine lights sometimes do not go off right away. To reset the check engine light, disconnect your battery, turn the lights on, on your car ( to drain any power left in the computer systems), reconnect the battery and the light should be off. If it comes back on, the EGR valve was not installed properly.
