Q: Check Engine Light is on and I've noticed one minute my gas says a half a tank and the next it's at a quarter

asked by on October 02, 2016

My check engine light came on recently and I just got my fuel pump replaced and thought I had everything under control. It came on again and now I really have no idea what could be going on other than something with the gas. Iv noticed that some times it will say it's at a certain point say a half a tank and I would shut the car off and turn it back on and it would be lower than that. I'm not really sure what could be going wrong with it. There's no sounds or anything coming from my car either.

My car has 112014 miles.

Hello. This is most likely a faulty fuel sending unit. This is a unit that sits in the fuel tank that sends a signal relaying how much fuel is in the tank. These commonly go bad on many cars. If you need help having this looked at, a certified professional from YourMechanic can come to your car’s location to diagnose the Check Engine Light more thoroughly and perform repairs that are needed.

Windshield wiper is not working

If one of your wipers isn't working while the other is, I would suggest replacing both wiper arms. Wiper blades have a very short lifespan compared to other parts on your vehicle and must be replaced more frequently.
