Precision Diagnostics. Trusted Expertise.

At Merrick Tire Center, engine diagnostics go beyond basic code reading. We combine advanced diagnostic technology with methodical, hands-on testing to deliver precise results and confident recommendations. Every vehicle is evaluated with the same attention to detail you expect from a high-end service experience.

Our comprehensive diagnostic process may include:

• Advanced scan tool analysis to retrieve fault codes, monitor live engine and emissions data, and identify performance irregularities

• Check engine light evaluation with system-by-system analysis to determine the true source of warning indicators

• Smoke testing to accurately locate EVAP system leaks, vacuum leaks, and hard-to-detect emissions faults

• Electrical and sensor diagnostics to verify voltage, signal integrity, and circuit performance

• Fuel system testing to assess fuel pressure, injector operation, and delivery efficiency

• Vacuum and air intake inspection to identify leaks that affect drivability and fuel economy

• Mechanical verification to confirm proper operation of critical engine components

By pairing state-of-the-art diagnostic equipment with experienced technicians and a disciplined testing approach, we eliminate guesswork, avoid unnecessary part replacement, and provide clear, honest recommendations—so you can make informed decisions with confidence.
