Bosch Oxygen Sensor P/N:15090
Bosch 13034 oxygen sensor for the 1991-1993 Volvo 940 4-cylinder 2.3L and other vehicles gives the ECU air-fuel-ratio measurements from the exhaust. This heated narrow-band sensor helps the ECU hold stable combustion control and keep emissions down.
A worn oxygen sensor can show up as a check engine light, rough running or poorer fuel economy. Before you replace the sensor, rule out exhaust leaks and damaged wiring first, since those can set similar codes.
This upstream sensor is a direct-fit replacement for the 1991-1993 Volvo 940 4-cylinder 2.3L, the 1989-1992 Volvo 740 4-cylinder 2.3L and the 1990-1992 Volvo 240 4-cylinder 2.3L. The fitment calls for one upstream sensor per vehicle, and this listing is one sensor. Driving a different Volvo? Run your year and engine through the "Vehicles it fits" section.
