2018 Toyota Prius Prime Check Engine Light Codes

The 2018 Toyota Prius Prime can log a range of diagnostic trouble codes that point to emissions, hybrid battery, or sensor issues. In Albuquerque, drivers rely on Larry H. Miller American Toyota Albuquerque for clear explanations and accurate pricing. Common codes include P0420 (catalyst efficiency), P0171/P0174 (lean conditions), and hybrid-specific codes affecting battery management and charging. Ignoring these codes risks higher repair bills: a failing catalytic converter can escalate into engine damage and emissions failures that cost thousands, while untreated lean conditions accelerate component wear and reduce fuel economy. Early diagnosis reduces both immediate and long-term costs by identifying the correct repair—often a sensor replacement, gasket repair, or targeted service—completed with OEM parts that last longer and maintain fuel efficiency. Our factory-trained technicians use Toyota-grade scanners and test procedures to provide reliable estimates and efficient repairs. We encourage drivers to check current service specials and schedule service to address codes promptly and preserve vehicle value.
