As part of your Buick's fuel delivery system, your O2 sensor relays important information to its engine control unit. It monitors the current air/fuel mixture your engine, which the ECU uses to either increase the air intake or the fuel flow in order to maintain just the right ratio. Without that sensor, your gas consumption skyrockets, your engine hesitates or your vehicle refuses to even start. Stop these problems before they start with a new O2 sensor for Buick. Keep your gas flow constant with a replacement sensor from AutoAnything, available with added savings thanks to our 1-Year, Lower Price Guarantee.
