2025 Toyota Crown Check Engine Light Codes

The most common check engine light codes for a 2025 Toyota Crown typically involve oxygen sensors, catalytic efficiency (P0420), misfires (P0300–P0304), and battery or charging-related codes for hybrid components. Left unaddressed, each presents escalating costs: a faulty O2 sensor can reduce fuel economy and damage the catalytic converter (repairing the converter is costly), misfires cause engine wear and raise fuel use, and charging or battery faults in hybrid systems can lead to expensive battery module repairs. At Herb Chambers Toyota of Auburn we prioritize transparent diagnostics and preventative care — our team explains the likely cost scenarios and timelines so you can make informed choices that reduce long-term expense. Using OEM parts and factory procedures, we minimize repeat visits and protect warranties; many customers find dealership-quality diagnostics ultimately cost less than repeated independent repairs.
