Bad Air/ Fuel mixture sensor warning for ALL Yaris owners

[cali yaris]

oyota calls their upstream O2 sensor an A/F mixture sensor.

Correct, and it's a very unusual 0-5v sensor, made by Denso for Toyota OEM. No one else makes it, and you have to get it from Toyota (or a salvage yard )

The rear one, between the cats, is an O2, however.

My header install went fine -- no cross-threading and no CEL's.
