At Don And Harold’s Car Care in Long Beach, California, our expert technicians specialize in check engine light diagnostics and take pride in honest, accurate assessments.

Sometimes the issue is as simple as a loose gas cap, a faulty sensor, or low fluid levels. Other times, it could point to something more serious like an emissions issue or engine misfire. Either way, our team uses advanced diagnostic tools to get to the bottom of the problem quickly and correctly.
