2017 Toyota Highlander Hybrid Check Engine Light Codes

In Albuquerque, the most frequent check engine codes for a 2017 Toyota Highlander Hybrid involve OBD-II emissions sensors (like P0420), oxygen sensor readings, and hybrid system alerts related to battery state or inverter function. Left unaddressed, a P0420 can reduce fuel economy and damage the catalytic converter — repairs that become significantly more expensive than an early diagnostic. Oxygen sensor failures increase emissions and reduce MPG, costing more in fuel over time than the diagnostic itself. Hybrid system alerts may indicate battery cooling, state-of-charge imbalance, or auxiliary battery concerns; ignoring those warnings risks traction loss, reduced electric assist, and costly battery replacement. At Larry H. Miller American Toyota Albuquerque we combine OEM diagnostics with certified hybrid training to pinpoint codes quickly. That faster, accurate resolution saves you money today and prevents cascading failures tomorrow. Our service advisors will explain estimated repair costs, available warranty coverage, and any applicable service specials, then help you schedule service at a convenient time.
