I am about 1000 miles away from home and got a check engine light. It is the O2 sensor Bank1 Sensor 1. Am I doing any engine damage by not replacing the sensor until I get home?

It is against the firewall, away from air flow.

Damage to the catalytic converter by overheating is sure to occur in a thousand miles. It could possibly catch fire. If at all possible have the sensor replaced or the vehicle towed.

A toyota dealer may be a closer option with the correct part available. Stay away from a non-Denso part. (not toyota)

The O2 sensor is probably open or infinity on a meter, burnt from overheating. The high ohm value now on this sensor is telling the ECM to lean the bank of three cylinders, contributing to the overheating.

A self-destructive cycle.

What was the actual code?

It might just be a split second reading showing a lean condition. The P0171 is the one I am thinking you got and it could also have been a dirty MAF that can be cleaned.

Did you attempt to reset the light after you got the code?

Otherwise, you can pull the EFI fuse in the fusebox for a few second (with the key out of the ignition when you do this) and that will reset it.

From what I have read, the RX has a default condition, which means the vehicle won't run as efficiently when this occurs (an actual O2 sensor issue).

Actual codes are P1130 and 1135. I have pulled the fuse and the check engine light comes back on.

But a thousand miles, sixteen hours .... at high speed. I'd get it fixed first.

I still think he can drive it, but vehicle just won´t run as efficiently, and you should see a decrease in MPG.
