Pre-Cat Oxyggen sensor replacement

dh5379 · 07-25-2013, 12:01 AM

Hey,
Does anyone know if the computer has to be put in adaptation mode when replacing the O2 sensors? Seems like my fuel mileage has gone down dramatically after the dealer replaced my pre-cat O2 bank 2 defective sensor.

When asked if the computer was put in adaptation mode the service advisor told me that it would adapt over 90 starts. That seems quite odd.

Thanks, David

You can reset adaptations using INPA or similar scan tool.

Anyone know about the factory procedures for Oxygen sensor replacement? Is the adaptation supposed to be reset after installing a new O2 sensor?
