You MUST record and report the exact error code numbers.

Go back to your garage and ask what the code was in each instance. There
are about a dozen error codes that can involve the secondary oxygen sensor.

If the same error keeps recurring in spite of several sensor replacements,
than there's something else wrong, like a cracked exhaust manifold or
misrouted wiring.
