CHEVY FLEX FUEL SENSOR

2000 Chevrolet S-10

Engine Performance problem
2000 Chevy S-10 4 cyl Two Wheel Drive Manual 95000 miles

I am getting P0178 & P0179 codes, Fuel composition Sensor Circuit Low & High. My question is, since I don't use any gas with alcohol in it, can I somehow bypass this sensor. I hate to spend $650+ on something I don't need just to get the check engine light to go off.

There is a company called tandselectronics selling bypass units on ebay called a Flex Fuel replicator for $150. You just unplug the sensor, plug in the box and you are done.
