2027 Toyota Camry Check Engine Light Codes

At Larry H. Miller Toyota Peoria in Peoria, AZ, we see a predictable set of check engine light codes on the 2027 Toyota Camry: P0420 (catalyst efficiency low), P0300 (random/multiple misfire), P0171 (system too lean), P0442 (EVAP small leak), and various oxygen sensor and MAF sensor codes. Each code points to different risk and cost profiles—ignoring a P0420 can mean catalytic converter failure and a $1,000–$2,000 replacement; unresolved misfires (P0300) risk piston and catalytic damage that can exceed several thousand dollars; lean conditions or EVAP leaks lead to poor fuel economy and emissions failures. Our certified Toyota technicians use OEM diagnostics to isolate the root cause quickly, which reduces unnecessary parts replacement and labor. Choosing our dealership frequently costs less over time than repeated independent attempts because we fix it right the first time, back work with factory warranties, and provide transparent estimates. To protect your 2027 Toyota Camry from escalating repair costs, schedule service and check current service specials before you arrive.

2027 Toyota Camry Check Engine Light Reset

Resetting the check engine light on a 2027 Toyota Camry is technically straightforward with an OBD-II scanner, but resetting without diagnosing the underlying cause risks repeat failures, hidden damage, and voided warranty coverage.

Our process: we read freeze-frame data and stored codes, test suspect components with factory-level tools, and then clear the light only after confirming the repair or advising you on necessary steps. This transparent approach protects your vehicle’s longevity and ensures any parts used are OEM quality, preserving performance and resale value. We stand behind our work with manufacturer-backed warranties and certified technicians, and we provide clear quotes, repair timelines, and available discounts. If cost is a concern, ask about financing when you schedule appointment or review our service specials to find current savings.
