2012 Honda Accord Check Engine Light Codes
The 2012 Honda Accord often registers a handful of common codes that we see regularly at Larry H. Miller Honda Boise. Codes such as P0420 (catalyst system efficiency), P0300 (random/multiple cylinder misfire), P0171 (system too lean), and P0446 (EVAP vent control) are typical culprits. Left unaddressed, these issues can escalate quickly: a faulty oxygen sensor or EVAP leak can reduce fuel economy and driveability, while a persistent misfire may cause internal engine damage or premature catalytic converter failure—repairs that can cost hundreds to thousands if delayed. Our Boise service center provides an efficient diagnostic workflow: we scan and interpret codes, outline repair options with transparent pricing, and use OEM parts to restore factory performance.
