I read that replacing a bad oxygen sensor can improve fuel up to 40%. Good tires also help. I think I"m getting around 18 to 22 mpg on mine and that's about 40%. It could be true!

@@michaelshahen thanks for reply. do you know if all the sensors are the same? i found an ebay auction for 4 bosch sensors for only $60. they have generic ends without connectors that need to be crimped. think its legit?

​@@fernando651 They all look similar but they are not the same. Upstream sensors primarily help in adjusting the air-fuel mixture. Downstream sensors monitors the efficiency of the catalytic converter. You'll also notice the end color are different for downstream and upstream sensors. Typically a check engine light will turn on if a sensor is bad. If so, take the car to Autozone, Advance Auto, O'Reilly, NAPA and they can get the error code with an OBD2 sensor for free. The code will tell you which oxygen sensor is bad. Bosch is a good name, but it could be a fake. $60 dollars is cheap for 4. The sensors should cost between $20 and $30 dollars each. An actual Hyundai part would be double or triple that.

Good luck. I hope that solves the issue. PF on a Maytag is Power Failure that can happen during power surges. If you still have the old thermal fuse, and a multimeter, you can check the fuse for continuity, if you hear a beep the fuse is still good. If not, then the fuse needs replaced. Here’s a video I found that shows how ... if you have a multimeter. ruclips.net/video/HyCaoiQsyd0/видео.html
