Frequently Asked Questions

How much does a check engine light diagnostic cost for a 2014 Acura TSX?

• Typical diagnostic scans range from a complimentary check to a modest fee depending on the depth of testing; Nalley Acura provides clear estimates before work begins.
• We often cost less than independent shops while delivering factory-trained technicians and OEM tools — immediate savings on accurate repairs and long-term savings by preventing follow-up failures.
• If repairs are covered under warranty, they must be performed at a certified dealership to maintain coverage and ensure proper parts and procedure.
• Diagnostics can reveal simple fixes (e.g., gas cap or sensor replacement) or more complex issues; we prioritize transparent pricing and value.

What does it mean when the check engine light comes on in a 2014 Acura TSX?

• The light is a general alert from the vehicle’s on-board diagnostics — it can indicate anything from a loose gas cap to emissions or engine performance problems.
• Common causes include EVAP leaks, oxygen sensor failure, catalytic converter issues, ignition misfires, or fuel-system irregularities.
• Only a code scan reveals the specific trigger; Nalley Acura uses factory-grade scanners to read codes and recommend the right repair.
• Addressing codes early reduces repair costs and protects components like the catalytic converter from more expensive damage.

What is the first thing to check when the check engine light comes on?

• Check the gas cap — a loose or damaged cap is a frequent, simple cause and can clear the light after proper reseating or replacement.
• Note any drivability changes (stalling, poor acceleration, unusual noises or smells) and whether the light is steady or flashing.
• If the light is flashing, stop driving if possible and have the vehicle inspected immediately to avoid further damage.
• Bring your 2014 Acura TSX to Nalley Acura for an OEM-level scan; warranty-covered repairs must be done at a certified dealership to retain coverage.

What is the most common reason for check engine light on a 2014 Acura TSX?

• The single most frequent cause across many makes is a loose or faulty gas cap triggering an EVAP system code.
• Other common triggers include oxygen sensor failure, misfires, and EVAP leaks — these impact fuel economy and emissions if left unresolved.
• Nalley Acura’s factory-trained technicians quickly identify root causes with OEM diagnostic tools to avoid unnecessary part replacement.
• Timely service at our dealership often costs less than independent shops when factoring in accurate diagnostics, warranty protection, and long-term savings.

How long does a check engine light service take?

• Initial code read and basic diagnosis typically take 30–60 minutes; complex troubleshooting or intermittent faults may require additional testing.
• Simple repairs like gas cap replacement or a sensor swap can often be completed the same day; larger repairs follow a clear estimate and timeline.
• Nalley Acura emphasizes efficient turnaround using factory procedures and parts — this yields immediate cost savings and reduces the chance of repeat visits.
• Remember: repairs covered by warranty must be performed at a certified dealership to preserve coverage and ensure proper documentation.
