Does Advance Auto Parts Check Codes In 2024? The Insider Expert Guide

As an auto parts expert with over 10 years of experience, one of the most common questions I get asked is: "Can Advance Auto Parts check the codes when my check engine light turns on?"

I‘m here to provide the inside scoop on what to expect from Advance‘s free engine code scanning service in 2024.

A Peak Under the Hood: How Advance Scans Codes

The first thing to know is that Advance uses an OBD-II scanner plugged into your car‘s computer port under the steering wheel. This scans for any diagnostic trouble codes (DTCs) that sensors have triggered, with codes pointing to issues like:

  • Faulty oxygen sensor
  • Bad catalytic converter
  • Loose gas cap

However, here is exactly what Advance Auto‘s scanning process CAN‘T do:

  • Show code definitions or probable causes
  • Reset or turn check engine light off
  • Reveal enhanced or proprietary manufacturer codes

Staff also can‘t make repair recommendations beyond basic parts replacement.
