Bosch Oxygen Sensor P/N:13644
Bosch 15961 right oxygen sensor for the 1999-2003 Nissan Frontier V6 3.3L and other vehicles reports exhaust oxygen levels to the ECU. This Bosch O2 sensor is a switching-type unit that helps the ECU keep combustion steady and emissions down.
A worn oxygen sensor can show up as a check engine light, rough running or lower fuel economy. Before you replace this sensor, rule out an exhaust leak near it, damaged wiring and a loose connector, since problems there can trigger similar codes.
It is a direct-fit replacement oxygen sensor for the 2000-2003 Nissan Xterra V6 3.3L as well, and each of them takes one on the right side. This listing is one downstream right sensor; a sensor for the other side is a separate part.
Fit and size
Build and materials
One oxygen sensor with its wiring harness. A mounting bracket is not included.
Is this the oxygen sensor for the downstream right side of the 1999-2003 Nissan Frontier V6 3.3L?
Yes. Bosch 15961 is the downstream right oxygen sensor for the 1999-2003 Nissan Frontier V6 3.3L, and that side takes one.
Does Bosch 15961 come with a wiring harness and a mounting bracket?
Bosch 15961 includes a wiring harness. A mounting bracket is not included.
Is this Bosch premium oxygen sensor heated?
Yes, it is a narrow-band heated sensor that reaches operating temperature in under 10 seconds, with an M18 - 1.5 thread and a 22 mm hex.
How can I tell this oxygen sensor is wearing out?
A check engine light or a change in how the engine runs can mean the sensor is wearing out, though other faults can set these off too. A shop can read the codes and test it.
Does the Bosch 15961 need anti-seize on the threads?
No. Conductive anti-seize is already applied to the threads of the Bosch 15961, and its connectors are direct-fit.
