Aaaah yes ... the bad fuel problem-)

Yes, it can cause damage to the engine. Yes, it can damage a sensor.

Solution: go to an auto parts store that can check error codes. Then, the error code will say which sensor is bad.

Most likey it's these sensors (with estimated prices): MAP - $30 Oxygen - $20 and last (not a sensor) egr (valve) - $80 fuel injector - $70 each spark plugs - $2-15 fuel filter - $8

Contaminated fuel will certainly damage an 02 sensor and the cat as well. Yes. O2 sensors do wear out even under ideal conditions but bad fuel, racing fuel, fuel with lead accelerate the deterioating effects the exhaust gases & particles have on the sensor. Even when there is no sign of a problem it's not a bad idea to replace the O2 sensors at 60k or 70k as they can degrade slowly over time and impact the efficiency of the engine without being noticeable.

A bad oxygen sensor can cause power loss, reduced fuel economy and damage to your catalytic converter.

The computer can deliver the wrong amount of fuel resulting in poor performance, wasted fuel or valve damage, and that's IF it even runs at all.

Gas sensor? Not sure what you mean, could it be a Fuel gauge sensor? Oxygen sensor? Fuel pressure regulator?
