Question about Cars & Trucks
I have a Vauxhall Corsa 1.2 16V hatchback. 2day ago I noticed on the dashboard the light symbol car with spanner through it has come on solid and stays on all time when driving. The car runs perfectly no missfires or losz of power. I did a home diagnostics test on an Autel MS300 CAN OBD2 scanner and came on with one error which is P0170 fuel trim malfunction (bank 1). Please any ideas, many thanks, Tim.

Your car only has one bank, so this code applies for the entire engine. I'll provide a link that gives a good breakdown of what P0170 means, possible causes, and possible corrections.

What all this codes have in common is that every single one of them can be caused by a vacuum leak, so carefully check for cracked, loose or disconnected vacuum hoses, wiring to the coils, fuel pressure regulator, fuel injectors, specially on cylinder 2.
NOTE:After cylinder cut-out system is turned off, the system monitors (through misfire detection) if all intake and exhaust valves are open again.
NOTE:Misfiring may be caused by many faults in the fuel injection system. Usually a misfiring fault is stored with faults pertaining to other components. An engine mechanical fault could also cause a misfire condition.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.
