2012 Honda Pilot Check Engine Light Codes

The most frequent codes for a 2012 Honda Pilot seen at Larry H. Miller Honda Boise include P0420 (catalyst system efficiency), P0171 (system too lean), P0300 (random/multiple cylinder misfire), P0455 (EVAP large leak) and P0128 (coolant thermostat). Left unaddressed these codes can lead to significantly higher costs—P0420 untreated can require catalytic converter replacement (often $1,000+), misfires can damage the catalytic converter and ignition system, and EVAP leaks can worsen emissions and fuel economy. Bringing your Pilot to our Boise service center ensures a full OEM diagnostic that isolates root causes rather than guessing. Our certified Honda technicians use factory tools to verify whether a simple fix—like an oxygen sensor or gas cap—or a larger repair is needed. That accuracy translates to immediate savings by avoiding unnecessary parts and long-term savings by preventing collateral damage. We combine that expertise with comfortable customer amenities, clear written estimates, and a commitment to getting you back on the road quickly.

2012 Honda Pilot Check Engine Light Reset

Resetting the check engine light on a 2012 Honda Pilot requires more than clearing a code; it requires confirming the underlying fault is resolved. At Larry H. Miller Honda Boise we diagnose the fault, repair it with OEM parts, and verify the repair with a post-service scan so the code does not return. Simply clearing codes at home or an independent shop can mask a problem and risk repeat failures, wasted parts, or warranty denial. Our process emphasizes transparency—full explanation of findings, parts pricing, and written warranty coverage. We also highlight opportunities to save using our service specials and offer service financing to let you complete necessary repairs now and spread payments over time. When you schedule service with our Boise team, you get certified technicians, factory tools, and documentation that protects warranty rights and resale value.

Miller Honda Boise we prioritize flashing-light cases and will perform a rapid diagnostic to determine whether towing or immediate repair is required to prevent further damage.
