• Text and phone updates throughout your visit

It means the engine or emissions system stored an OBD-II fault code identifying the affected system.

On the 2025 Toyota Highlander Hybrid, causes range from a loose gas cap (EVAP leak) to ignition misfires or catalytic converter efficiency concerns. The code points to a system, not a single failed part, so verification testing prevents replacing components unnecessarily. Our Murray team reads live data and freeze-frame to determine what happened when the fault set.

• OBD-II code retrieval plus freeze-frame data review
• System pinpoint tests confirm the actual cause
• Written estimate with repair options after diagnosis

Common categories include EVAP leaks (often a loose gas cap), oxygen sensor faults, MAF sensor issues, misfires, and catalytic converter efficiency.

Hybrid powertrains still use conventional OBD-II monitoring for fuel, air, and emissions. Temperature swings along the Wasatch Front can aggravate EVAP small-leak codes, while altitude and winter fuel blends can influence mixture feedback. Our technicians confirm which component failed and why to avoid repeat faults.

• EVAP leaks: cap, purge, or vent faults
• O2 sensor or catalytic converter efficiency codes
• Ignition misfire or MAF contamination

Steady light: drive cautiously to service; flashing light: stop driving to avoid catalytic converter damage from severe misfire.

If the light is steady on your 2025 Toyota Highlander Hybrid, reduce load and schedule an inspection soon. A flashing light signals active misfire that can overheat and damage the catalyst—towing is recommended. In either case, our Murray dealership can quickly scan and isolate the cause.

• Steady CEL: limited driving is generally acceptable
• Flashing CEL: risk of catalyst damage—seek immediate service
• Schedule an appointment for prompt diagnosis

Parts stores read codes; our dealership performs full diagnosis with Toyota Techstream, isolation testing, and a written estimate.

OBD-II codes have multiple potential causes. In Murray, our factory-trained technicians access Toyota-specific data, run active tests, and confirm the fault before recommending repairs—reducing guesswork and repeat visits. You also get documentation that supports warranty coverage when applicable. Check service specials before you come in.

• Factory scan tool access and OEM test plans
• Pinpoint testing to verify the root cause
• Clear estimate and repair roadmap

No—resetting clears readiness monitors, and Utah emissions testing can fail vehicles with “Not Ready” monitors.

Simply clearing codes on a 2025 Toyota Highlander Hybrid erases stored data and may require specific drive cycles to reset monitors. If an underlying fault remains, the light will return. Our Murray team repairs the root cause and confirms readiness, helping you avoid retests and delays.

• Readiness monitors must be set to “Ready”
• Drive cycle may be needed after repair
• We verify no codes and completed monitors before you test

Your visit begins with a professional OBD-II scan on the 2025 Toyota Highlander Hybrid using Toyota Techstream, capturing codes, freeze-frame data, and live parameters. A technician reviews symptom details and performs isolation testing tailored to the stored fault—such as smoke testing for EVAP leaks, fuel-trim analysis for mixture faults, or misfire counters for ignition issues. Youll receive a written estimate before any repair is performed, so you can make an informed decision. Warranty work generally requires a certified facility and proper documentation; our inspection and estimate are structured to support that requirement. If youre price-shopping, remember that complete diagnosis prevents unnecessary parts replacement. Ready to move forward? Schedule service or review current service specials today.

Drivers often encounter EVAP small-leak faults (e.g., loose gas cap), oxygen sensor performance codes, MAF-related mixture faults, misfire codes, or catalytic converter efficiency alerts on the 2025 Toyota Highlander Hybrid. EVAP and O2 sensor issues can reduce fuel economy and increase emissions; left unaddressed, misfires can overheat and damage the catalytic converter, leading to far higher repair costs. Converter-efficiency codes may stem from upstream issues—solving the root cause early protects the catalyst. Our process confirms what failed and why, so you replace only whats necessary.
