after changing a glowplug how do u reset the check engine light
The conventional way is an OBD ... The down and dirty way is to disconnected then reconnect the battery after about 10 seconds
Sometimes disconnecting the battery(s) will do it. You could drive it by your local Autozone or similar parts store and ask them to reset the code. They usually do this for free.
Some AutoZones won't reset alarms ... I asked ours why they will read them but not reset them and they said "Liability"
With the OBD II system it is done with a scan tool. Or, assuming that the problem is solved the light will go out on it's own once the computer determines the problem is fixed. Usually within 60 ignition cycles. HTH. -Jim
I agree with Js08016 about ignition cycle reset. I had the similar situation only I didnt replace the glowplug since I believe it was a faulty code do to block heater electrical interference. Checked the code with my scanner but didnt clear it just to see if it was a legite issue. Light stayed on for two days then just went away. Hasnt come back even at air temps of -10°F!
