Seat belts are very important safety features, and you should never be in a moving vehicle without wearing a seat belt that is properly fastened. Buckling your seat belt is easy, and only takes a few steps: 1. Slowly pull...

Hey there, thanks for writing in about your 1998 Saturn LS. This sounds like you have a short somewhere in the electrical system. I would start by testing the power supply to each of the various components or first try...

All modern cars are equipped with an Evaporative Emission Control (EVAP) system. The EVAP system prevents fuel vapors from the fuel tank from escaping into the atmosphere. The EVAP system collects and temporarily stores the fuel vapors in the charcoal...

Hi there. First check the fuse box for any blown fuses (https://www.yourmechanic.com/services/fuse-replacement). Then check the relays to see if any of the lights relay (https://www.yourmechanic.com/services/rear-lights-are-not-working-inspection) are activating. If the relays are activating, then you will need to check the wiring...

Hi there. When the two codes P0171 (https://www.yourmechanic.com/article/p0171-obd-ii-trouble-code-system-too-lean-bank-1-by-andrew-quinn) and P0174 (https://www.yourmechanic.com/article/p0174-obd-ii-trouble-code-system-too-lean-bank-2-by-blake-griffin) come up for a lean system on both banks of your engine, then either all of the fuel injectors are not working properly or your fuel pressure has dropped....

The transmission control module has various sensors such as...

A common failure for these systems is water intrusion into the camera. If you look closely at the lens and see a droplet of water inside the camera, moisture has made it's way into the unit and may have caused...

The problems will be two different ones unless the failure code is for loss of fuel tank vapor pressure. I would recommend having fuel leak fixed first and then having the computer scanned for the failure code to see what...
