'94 dtc 13, 63, 41

Anybody know the diagnostic sequence for BOTH sides failure of heated o2 sensors?

I know the sensors themselves are ok - they don't fail at the same time. The 41 failure Ignition Control Circuit Open has to be the problem.

All 3 are brand-spankin' new fresh this morning, and they are 'H' codes - History, since it is intermittent.

Any ideas?

Thanks

Did you clear them and they returned as current codes?

Shep,

Post has been moved from Non-Specific to Corvette forum since there was a duplicate post there.

No, they are not cleared.

The light(s) came up and went out several times on a one hour trip.
