Engine Diagnostics

Expert Vehicle Diagnosis & Performance

Modern vehicles rely on complex electronic systems. When something goes wrong, our advanced diagnostic equipment pinpoints the issue fast -- saving you time and money on unnecessary repairs.

Check Engine Light Diagnosis

Your check engine light can indicate hundreds of different issues. Our technicians use professional-grade OBD-II scanners to read and interpret diagnostic trouble codes (DTCs). We don't just read the code -- we diagnose the root cause:

  • Engine misfires and performance issues
  • Emissions system faults (catalytic converter, O2 sensors, EGR valve)
  • Fuel system problems (injectors, fuel pump, pressure regulators)
  • Ignition system issues (coils, spark plugs, timing)
  • Sensor failures (MAF, MAP, throttle position, coolant temp)
  • EVAP system leaks and purge valve issues

Complete Vehicle Inspection

Beyond the check engine light, we perform comprehensive vehicle inspections:

  • Pre-purchase inspections -- know what you're buying before you sign
  • Multi-point safety inspections
  • State inspection preparation
  • Electrical system testing (alternator output, battery load test, parasitic draw)
  • Cooling system pressure testing
  • Compression and leak-down testing

Why Diagnostics Matter

A proper diagnosis prevents throwing parts at a problem. Many shops will replace the part a code points to without verifying it's the actual cause. Our approach:

  1. Scan for trouble codes
  2. Verify with live data and freeze frame analysis
  3. Perform targeted testing to confirm the root cause
  4. Provide a clear estimate before any work begins

This saves you money -- you only pay for what actually needs fixing.
