Walker Products 250-241196 Oxygen Sensor 4-W Direct Fit Narrow-Band - Walker 250-241196

OE Base Sensor | B1S2

The oxygen sensor monitors the oxygen content of the exhaust gases and sends feedback to the ECM, which uses this information to fine-tune the fuel mixture for efficient combustion and low emissions. Signs of failure include: a check engine light with an O2 sensor code, poor fuel economy, a rough idle, or a vehicle that fails an emissions test. Replace a worn oxygen sensor to restore proper closed-loop fuel control and fuel efficiency.
