Check Engine Diagnostics in Sunnyvale, TX
Your local shop for diagnostic
Our diagnostic fee applies toward the repair if you have us do the work. We use bidirectional scan tools and a smoke machine for vacuum leaks — we find what the parts-store reader misses. Most codes diagnosed within an hour.
Sunnyvale is ten minutes south on Town East Boulevard. Sunnyvale customers are usually combining the visit with a Town East errand, so we lean on our twenty-five-minute oil change and one-hour brake-job slots.

How we handle it
The same process on every visit, whether it's a quick check or a full repair.
Written estimate before we start
You approve the number before a single tool comes out. No surprise line items at pickup.
ASE-certified techs on every job
Certified, trained and torque-checked — the same standard whether it's a $40 job or a $4,000 one.
Hunter® equipment, dealer-level precision
Camera-based alignment and road-force balancing most independent shops don't carry.
Same-day service on most repairs
Drop it off in the morning — most jobs are done the same day. We call before anything changes.
Common question
Our diagnostic fee applies toward the repair if you do the work with us. Generic code readers (the kind parts stores use) only show the surface code. We use bidirectional scan tools that read manufacturer-specific codes plus live sensor data, which is what we need for intermittent problems.
