2020 Toyota 86 Check Engine Light Codes

At Nalley Toyota Union City in Union City, GA, diagnosing common codes on a 2020 Toyota 86 is routine: P0420 (catalytic efficiency), P0171/P0174 (fuel trim/lean condition), P0300-P0304 (misfires), and sensor codes such as P0130–P0167 for oxygen sensors. Left unaddressed, a P0420 can lead to a failing catalytic converter—repairing that later is significantly more expensive than prompt diagnosis. Lean codes can cause increased fuel use and driveability issues; misfires risk engine damage and reduced performance. Our certified technicians use Toyota OEM scanners and factory procedures to identify root causes and present transparent repair options. Choosing Nalley Toyota Union City not only delivers accurate codes and clear cost estimates, but also yields immediate and long-term savings through correct repairs, OEM parts, and warranty protections. We frequently offer competitive pricing that competes with independent shops while providing higher standards of service.
