Not sure why the donation isn't showing?

The two last codes have to do with the fuel composition sensor that is located on the frame rail.

Po178 says the sensor is reading under 45 hertz and the po179 says the sensor is reading over 155 hertz.

I can send some info, but need a e-mail address to send it to. Check the connector going to it for corrosion for starters.

I have the same code thus the same problem with my 2001 S-10. I looked in manuals and all but they have nothing about how to fix the problem. If someone can send me some info on how to take care of it, I would relly appreciate it.
