[s-cars] HELP: "Rusted" Ox Sensor

[Vincent Frégeac]

Light rusty deposit is just fine. It doesn't mean the Ox Sensor is fine
but at least the exhaust gas is like it should. I don't know either for
mine. If the dealer has done his job properly with the PO, it's 40K
miles old. If the dealer bypassed the sensor replacement during the
timing belt job, it's 100Kmiles old which may explain the thickness of
the deposit.
