Check Engine Light Reset

The proper reset for a check engine light on a 2012 Acura TSX Sport Wagon begins with accurate diagnosis, not a simple code clear. At Park Place Acura in Plano, TX, our technicians use Acura factory scan tools to capture stored and pending codes, inspect related systems, and address root causes before clearing the light. A raw reset without repair may temporarily extinguish the indicator but leaves faults unresolved, resulting in recurring lights or later damage. We document test results and repairs, using OEM parts and following Acura service procedures so your vehicle completes required drive cycles and the on-board diagnostics verify a true repair. That transparency saves you money over time: precise repairs avoid repeat diagnostics and protect fuel economy and emissions compliance. If you prefer an appointment, schedule service online; check our service specials for discounts. We also offer service financing to help you get necessary repairs now and pay over time while preserving warranty coverage.

2012 Acura TSX Sport Wagon Check Engine Light Codes

Common trouble codes for the 2012 Acura TSX Sport Wagon include P0171/P0174 (system too lean), P0300 (random/multiple misfires), P0420 (catalyst efficiency below threshold), P0440 (EVAP system fault), and P0135 (O2 sensor heater circuit). Left untreated, a P0420 can escalate — a failing catalytic converter can cost well over $1,000 to replace and is frequently caused by prolonged misfires or ignored sensor faults. Likewise, persistent misfires accelerate internal engine wear and can ruin the converter, while EVAP faults often lead to failed emissions tests and reduced fuel efficiency. At Park Place Acura in Plano, our technicians diagnose codes, outline costs, and present repair options with OEM parts and warranty protection. Immediate repair at our service center often results in lower total cost of ownership, thanks to accurate fixes, fewer repeat visits, and documented service history that preserves resale value.

Check Engine Light Flashing

A flashing check engine light on a 2012 Acura TSX Sport Wagon usually signals a severe condition, most commonly an active misfire that risks catalytic converter damage.
