22693-1JA0A Auto Oxygen Sensor Air Fuel Ratio Sensor For Nissan Cube Maxima Murano Quest

The 22693-1JA0A air-fuel ratio (A/F) sensor is the upstream regulating probe used on the Nissan VQ35DE 3.5 V6 and MR18DE 1.8 petrol engines across the Cube, Maxima, Murano and Quest ranges. Unlike a conventional narrow-band oxygen sensor, the A/F sensor measures the exact oxygen content of the exhaust gas and returns a linear signal to the ECU, so the stoichiometric air-fuel ratio can be held precisely under all driving conditions.

The integrated heater brings the planar ceramic element to operating temperature within seconds of a cold start, allowing the ECU to enter closed-loop control earlier and reducing cold-start emissions. The sensor features a stainless-steel shell, a planar zirconia ceramic element, and a laser-welded protection tube against contamination and thermal shock.

• Four wires, two circuits: two wires feed the internal heater; two carry the A/F sensor signal. The sensor outputs a linear current signal rather than a switching voltage.
• Regulating probe: fitted before the catalytic converter as the ECU's primary fuel-control input; it is not interchangeable with the post-catalyst oxygen sensor.
• Fitting position: front / passenger side (bank 2 on VQ35DE applications). Confirm against the original sensor position on your vehicle.
• Direct-fit: rectangular 4-pin plug and pre-terminated cable — no cutting or splicing required.
• Torque: tighten to the vehicle manufacturer's specification (typically 40–55 N·m on an M18 x 1.5 boss). Do not use silicone-based sealant anywhere near the sensor.

Cross-reference numbers are listed for identification only. Always verify physical fitment — connector shape, pin count, cable length and thread size — against your original part before installation.

Vehicle list is compiled from aftermarket catalogue cross-references and is indicative only. Please confirm by OE number and by comparing the original sensor before ordering.
