O2 sensor bad after 90K maintenance
Hi, I just has an independent do 90K maintenance on my RX300 2000. He didn't even touch the O2 sensors or anything close to them but they both came up bad immediately after the job. Same thing happened to a friend. What gives? Second question is what happens if I continue operating the vehicle with the check engine lit (presumably due to bad O2 sensors)?

I think he might be referring to the A/F (air fuel sensors). If you get this code, it can cause a slightly more than normal increase in fuel consumption. I'd confirm what code it was.

The guy that read the code said both O2 sensors. I'll get the codes again. The question remains; with a bad O2 sensor, does the computer default to a "no sensor" setting or what? Does that result in bad mileage, carbon buildup,engine malfunction?

I changed out the front brake pads, started the car up, CEL came on. I thought for sure it was the ABS system. Pulled the codes, O2 sensor.

If code still pops up, then you need to have some examine the timing belt itself.
There is another set of codes, 1345 and 1350 that are related to VVT sensors being bad, but this would not be the case with the codes you pulled up.

Briefly after the 60K service I averaged 18.2 mpg but its been 17 for most of the intervening 30K miles. I drive small towns, rural & mountain; Only about 20 % highway driving. What's a reasonable mileage under those circumstances?
