Frequently Asked Questions

How long does a check engine light service take?

• Most diagnostics on a 2025 Ram 1500 take 30–90 minutes with a modern OBD-II scan tool and visual inspection.
• If live-data testing or road tests are needed, plan for 1–3 hours; complicated repairs add more time.
• Our dealership often completes work faster and at lower total cost than independent shops because factory tools speed diagnosis and reduce repeat visits.
• If a repair is covered by warranty, it must be performed at a certified dealership to maintain coverage and ensure timely, authorized parts and labor.

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

• Check the gas cap first—loose or damaged caps on the 2025 Ram 1500 (regular unleaded) commonly trigger codes; tighten or replace if needed.
• Note any performance changes (stalling, rough idle, loss of power) and whether the light is steady or flashing.
• Use a scan tool at our dealership to read stored codes—this identifies system or sensor faults quickly and accurately.
• Prompt certified diagnosis prevents escalation; repairs covered under warranty must be completed at a certified dealership to preserve benefits.

What does it mean when the check engine light comes on in a 2025 Ram 1500?

• A lit check engine light indicates the vehicle’s powertrain or emissions system has logged a diagnostic trouble code—ranging from minor sensor issues to engine misfires.
• Codes can reflect anything from a loose fuel cap to oxygen sensor, MAF, or catalytic converter issues tied to the NAG engine and rear-wheel drivetrain.
• Reading codes at our dealership identifies severity; timely service often saves on fuel and prevents costly downstream repairs.
• Repairs under warranty must be done at a certified dealership to ensure coverage and correct factory procedures.

How much does a check engine light diagnostic cost for a 2025 Ram 1500?

• Typical diagnostic fees range from about $99–$149 for an initial scan and inspection; more complex diagnostics may add labor for live-data or road testing.
• Parts and repair labor vary by issue—sensors are relatively inexpensive, while catalytic converter replacement can be costly if delayed.
• Choosing our dealership often costs less than independent shops overall because accurate factory diagnostics reduce repeat work and prevent larger failures.
• Warranty-covered repairs must be completed at a certified dealership to maintain coverage and avoid out-of-pocket exposure.

What is the most common reason for check engine light on a 2025 Ram 1500?

• The most frequent triggers are loose or faulty gas caps, faulty oxygen sensors, mass airflow sensor issues, or minor misfires—each logged as an OBD-II code.
• Small sensor faults can increase fuel use and emissions; addressing them quickly conserves fuel and prevents catalytic damage.
• Our factory-trained technicians diagnose these quickly with OEM tools and genuine parts, delivering immediate and long-term savings vs. repeated fixes.
• Remember: any repair covered by warranty must be performed at a certified dealership to retain protection and ensure proper parts and labor.
