I was getting pretty bad gas mileage so I did a KOER test with a code tool. I found out my ECT was out of range. It also wasnt creating a check engine light. So I replaced the sensor and my gas mileage seems to have gone up. Ive put about 50 miles on it and the gas guage still reads full. Also the temp guage wasnt working and always read around 130. I replaced the sending unit for it and now it works. I know this topic has come up before and thought maybe I could help out some people out with this info. Both parts cost about $30.
