2019 Toyota Prius Prime Check Engine Light Codes

Common check engine light codes for the 2019 Toyota Prius Prime include P0420 (catalyst efficiency), P0171/P0174 (fuel trim), P0300 series (misfires), and hybrid-system codes related to battery charge or inverter function.

Miller Toyota Murray we perform a proper diagnostic, address the underlying fault with OEM parts, and then reset codes using factory tools so any recurring problem will be tracked accurately. This transparency ensures you won’t pay for repeated work and helps preserve warranty coverage—repairs under warranty must be performed at certified dealerships.
