2011 Acura TSX Sport Wagon Check Engine Light Reset

Resetting the check engine light on a 2011 Acura TSX Sport Wagon may seem simple, but it’s important to pair a reset with a proper diagnostic so the underlying fault is fixed and does not return.

2011 Acura TSX Sport Wagon Check Engine Light Codes

Common check engine light codes for the 2011 Acura TSX Sport Wagon include P0420 (catalytic converter efficiency), P0300–P0304 (misfires), and P0130–P0167 series (oxygen sensor circuit faults). Left untreated, P0420 can lead to poor emissions performance and eventual catalytic converter failure—repair costs rise significantly if a converter must be replaced. Misfires (P030x) cause rough running and can damage the catalytic converter over time, increasing repair costs and reducing reliability. Oxygen sensor failures degrade fuel economy and trigger cascading faults when left unresolved. Park Place Acura in Plano addresses these issues with fast, accurate diagnostics, OEM components, and factory-trained technicians who prioritize lasting repairs. Our approach emphasizes immediate savings from accurate diagnosis and long-term savings from using OEM parts and certified repair procedures. You can review current service specials, take advantage of financing, and schedule service online for a convenient experience backed by dealership trust and transparency.
