Check Engine Light Diagnostics and Repairs in Hemlock MI

Using its onboard computer as the brains of the operation, your car keeps a close eye on the function of all its major systems. When something goes awry, it sends up the warning signal in the form of your check engine light or other dashboard lights. As soon as that occurs, you can turn to our team at Hemlock Auto & Alignment for help figuring out the cause and completing the proper auto repairs.

Most Common Repairs Needed Due to Check Engine Light Codes

Depending on your car’s year, make, and model, your check engine light can come on for many different reasons, such as:

  • Oxygen sensor failure
  • Catalytic converter clog
  • EGR valve blockage
  • Thermostat stuck closed
  • Bad airflow sensor


If you’re lucky, the check engine light could just come on due to a loose gas cap, although you’ll still need the codes cleared after tightening it back up.

Since there are so many potential causes, it’s always essential to run a quick scan to figure out what’s going on and see if your car needs auto repair in Hemlock, MI. With that move, you can keep minor issues from escalating, resulting in serious repairs.
