Frequently Asked Questions

What is the most common reason for check engine light on a 2008 Toyota Tacoma V6?

• Common causes include ignition misfires, faulty oxygen sensors (O2), catalytic converter efficiency codes, and evap system leaks.
• Misfires (P0300-series) can damage the catalytic converter if left unchecked, increasing repair costs significantly.
• O2 sensors and evap leaks often start as inexpensive fixes but can trigger wider drivability problems if ignored.
• Having the vehicle inspected by our dealership preserves warranty eligibility for covered repairs; warranty work must be completed at a certified dealership.

• Our team will advise whether an immediate repair is needed or if a monitored approach is appropriate, always explaining cost and timeline up front.
• For any warranty-covered repair, remember that work must be completed at a certified dealership to maintain coverage.
