Give the engine's fuel management the accurate exhaust reading it depends on with the Bosch Oxygen Sensor 15099, a narrow-band, heated switching-type O2 sensor. It installs as a direct-fit replacement for the 1996-1997 Volvo 960 and the 1997-1998 Volvo S90 and V90, all with the L6-2.9L engine. This is the downstream sensor, mounted after the catalytic converter, where it measures oxygen in the post-cat exhaust and reports an air-fuel-ratio signal to the ECU to help monitor catalyst efficiency and support closed-loop combustion control.
Bosch builds this sensor with advanced ceramic elements and a metal housing to help it withstand exhaust heat and vibration. If a failed downstream oxygen sensor is the cause of a stored catalyst-efficiency code, replacing it with 15099 restores the monitoring circuit. Country of origin: United States. Manufacturer part number 15099.
Which vehicles does the Bosch 15099 fit?
It's a direct-fit replacement for the 1996-1997 Volvo 960 and the 1997-1998 Volvo S90 and V90 with the L6-2.9L engine. See the Buyer's Guide tab to confirm your vehicle.
Is this an upstream or downstream oxygen sensor?
This is the downstream sensor, mounted after the catalytic converter, where it monitors oxygen in the post-cat exhaust and reports readings to the ECU to help gauge catalyst efficiency.
Does it include a wiring harness or mounting bracket?
A wiring harness is included. A mounting bracket is not included.
What are the thread and connector specs?
It uses M18 x 1.5 threads with a 22 mm hex and a male rectangular connector with four blade terminals; the threads come with pre-applied conductive anti-seize.
What are signs this oxygen sensor may need replacing?
Signs may include a check engine light with an oxygen-sensor or catalyst-efficiency code, rough running, or poor fuel economy. Diagnose the cause before replacing, since these can have other sources.
