Ferrari Mailing List: UPDATE: 512TR Check Engine Light (1-6)

[Larry Bard (larrybard]

This morning first tried simply restarting car. Same result (i.e., Check Engine CYL 1-6 again illuminated). So turned off engine and tried a suggestion passed along by Clyde: turning off battery switch/knob for about a minute, then turning it back on and restarting the engine.  Voila! Check engine light disappeared. I believe Clyde's theory as to likely cause is minor corrosion of wiring over the years. Regardless, the light has disappeared -- at least for the time being.

I guess that fellow Clyde really knows something about cars -- especially including the 512TR. 🙂

Thanks to everyone who replied -- and of course special thanks to Clyde.

All,

Just as arriving home this morning from a relatively gentle drive (highways) of an hour or two, check engine light lit. Most likely cause O2 sensor? I'm due for annual inspection anyway, so will certainly have mechanics troubleshoot -- but am I correct that low risk of significant damage that might result from driving it about 10 miles despite check engine light?

Thanks,

Larry
