2017 Honda Pilot Check Engine Light in Murray, UT

It means the OBD-II system detected a fault and stored a diagnostic trouble code (DTC) identifying the affected system.

Your Pilot’s light could be triggered by something minor, like a loose gas cap, or by issues such as a misfire or emissions fault. At Larry H. Miller Honda Murray in Murray, UT, we use Honda-capable scan tools to read codes and freeze-frame data and then verify the actual failed part with pinpoint tests. This prevents parts swapping and gets you an accurate estimate before repairs.

• First, check and tighten the fuel cap until it clicks
• If the light stays on after a few trips, schedule service
• If the engine runs rough or the light flashes, stop driving and arrange a tow

The most common causes are oxygen sensor faults, EVAP leaks (often a loose gas cap), mass airflow issues, catalytic converter efficiency faults, and cylinder misfires.

Your 3.5L V6 uses multiple O2 sensors and an EVAP system that can set codes if a seal leaks or a component fails. Misfires may arise from ignition or fuel delivery concerns and, if ignored, can overheat the catalytic converters. Our Murray team confirms root cause with live data and isolation tests so you fix what’s actually broken.

• Typical code families: P0420 (catalyst), P030X (misfire), P0171 (lean), P0442/P0455 (EVAP)
• Note symptoms (rough idle, poor MPG, hard starts) to share with your advisor
• Book a diagnostic now: schedule service

A steady light generally means you can drive cautiously to service, but a flashing light signals a severe misfire—stop driving and arrange towing to prevent damage.

Across the Wasatch Front, climbs and freeway speeds can stress an engine with an active fault. A flashing light can quickly overheat and damage the catalytic converters. If the light is steady and the Pilot runs normally, drive gently to Larry H. Miller Honda Murray; if it flashes or runs poorly, tow it to protect the powertrain.

• Steady light: reduce load, avoid hard acceleration, head to service
• Flashing light: shut down to prevent converter damage
• Set an appointment: schedule service

A parts store reads a generic code, while dealer diagnostics use Honda factory-capable tools, service information, and pinpoint testing to find the exact cause.

One code can have multiple root causes. Our Murray team reads live data, freeze-frame, and Mode $06 test results, then confirms the failure with isolation tests like EVAP smoke testing or ignition checks. You receive a clear, written estimate before any repair so you can decide with confidence.

• Access to Honda technical bulletins and guided test plans
• Verification testing prevents guesswork and repeat visits
• Transparent recommendations with a written estimate

No—clearing the light resets OBD-II readiness monitors, and Utah emissions testing fails vehicles with not-ready monitors or active faults.

To pass, the underlying problem must be repaired and the system must complete drive cycles so monitors show “ready.” Simply clearing codes may hide the symptom briefly, but the test looks for readiness, not just a dark MIL. We can repair the cause, confirm readiness, and provide documentation for testing.

• Address the root cause before inspection
• Complete drive cycles so monitors set to “ready”

A flashing light indicates an active, severe misfire that can damage the catalytic converters, so you should stop driving immediately and arrange a tow.

Unburned fuel entering the exhaust can overheat the converters within minutes, especially under load. Our technicians in Murray will scan for misfire counters, check ignition and fuel delivery, and verify compression if needed. Prompt diagnosis protects both performance and emissions components.

• Do not continue driving with a flashing MIL
• Note recent fuel-ups or symptoms (shaking, loss of power)
• Tow in and schedule service for priority diagnosis

For a thorough, accurate result, our process moves from data to verification. We begin with an initial OBD-II scan to capture DTCs and freeze-frame data, then review system readiness and Mode $06 test results to see which monitors failed and under what conditions. Next, a targeted visual inspection checks connectors, hoses, and obvious faults. We follow with isolation testing as needed—EVAP smoke tests, fuel trim analysis, MAF/A/F sensor checks, ignition assessments, and, when appropriate, compression or leak-down testing. You receive a written estimate before any repair is performed. This approach avoids guesswork and ensures you only approve work that addresses the confirmed cause. Ready to proceed?

Drivers from Salt Lake City, Millcreek, Taylorsville, Sandy, and Holladay rely on our Murray team for precise check engine diagnostics. Honda-capable scan tools read more than basic codes: we evaluate freeze-frame snapshots, Mode $06 data, live sensor values, and actuator responses to pinpoint root cause. Utah’s temperature swings can surface EVAP and air-fuel mixture faults; our isolation tests confirm leaks or component failures before parts are replaced. You’ll leave with clear findings and a written estimate so you can plan next steps.

Several OBD-II codes appear frequently on the 3.5L V6. P0420 typically indicates reduced catalytic converter efficiency, which can stem from prolonged misfires or exhaust leaks; ignoring it risks costly catalyst replacement. P0301–P0306 denote cylinder-specific misfires that, left unaddressed, can overheat converters and degrade drivability. P0171 (system too lean) may point to vacuum leaks, MAF/A/F sensor errors, or fuel delivery issues; continued operation can harm valves and converters. EVAP codes like P0442 or P0455 suggest small or large leaks—sometimes as simple as a loose cap, other times a canister, valve, or line fault. O2 sensor and heater codes (e.g., P0135) affect mixture control and emissions performance. Bring your 2017 Honda Pilot to Larry H.
