They did not carry the sensor and haven't been able to find it anywhere besides the dealer. They all have the rear O2 sensor but not the front pair of air/fuel ratio sensors.

Acutally, I was told it is the front two Air/Fuel Ratio sensors that need to be replaced. I have not been able to find these anywere except the dealership for $300+ each. Any one know of another source for them?

Now is this the "air fule ratio sensor" i was told they were $300 each. Any place to buy them cheaper?

How difficult is it to replace the O2 sensors for a RX300. Mechanic said check engine code was due to a bad O2 sensor and that we should replace both.

Where are these located? Best place to buy them?

Check Engine light is on, had it checked out and was told the O2 sensor needs to be replaced and that I should do both. Quotes have been from $900-1200. I think I can do this myself. What sensor (brand) should I use. Are they hard to get to? Will I have to reset the error code?

Thanks,

Would this be the same for a RX300. I was told the O2 sensors (both) should be changed. I am thinking of changing them myself and wanted to know how difficult it would be. Onced changed will I have to reset the error code?
