2018 Honda Clarity Check Engine Light Codes

The most common check engine codes for a 2018 Honda Clarity in Boise often relate to emissions sensors, oxygen sensors, EV/charging components, or fuel system anomalies. At Larry H. Miller Honda Boise we identify codes such as P0420 (catalyst system efficiency), P0130 (oxygen sensor circuit), and charging-system codes that can be unique to plug-in hybrids. Leaving these codes unaddressed can lead to decreased fuel economy, reduced electric range, failed emissions tests, and in some cases damage to hybrid battery components — which results in much higher repair costs over time. Our certified technicians run OEM-level diagnostics and provide full estimates with transparent pricing; addressing issues early saves money immediately by preventing cascading failures and delivers long-term savings through improved efficiency and extended vehicle life. We maintain a streamlined service flow in Boise, ID, and use genuine Honda parts so repairs meet factory standards.

A flashing check engine light on a 2018 Honda Clarity is an urgent indicator — it usually means a severe misfire or a condition that risks catalytic converter damage and reduced drivability.

Miller Honda Boise we treat flashing codes as a priority and will rapidly triage the vehicle to isolate the fault, explain repair options, and provide timeline and cost estimates.
