Our take on the Denso Oxygen Sensor 234-4738

The Denso 234-4738 is a heated four-wire oxygen sensor that fits directly in place of the original sensor, with a 22.83-inch lead. Denso supplies oxygen sensors to several automakers as original equipment, so this unit is built to the same fit and connector standard rather than needing splicing. It suits owners replacing a failed upstream or downstream sensor on the specific vehicles it is listed for. Against generic sensors, the direct-fit plug and heated element are its main advantages; the trade-off is that it only fits the applications Denso lists, so the part number must match the vehicle.

Questions and answers

Is this a direct-fit sensor or a universal one?
It is a direct-fit sensor with a factory-style connector and a 22.83-inch lead, so it plugs into the original harness without splicing.
What does the four-wire heated design mean?
Two wires carry the sensor signal and two power the heater, which brings the sensor up to temperature quickly so the engine can go into closed-loop fuel control sooner.
How do I know it fits my car?
Match the Denso part number 234-4738 to your vehicle's listed application and to the sensor position being replaced. Engine and position matter, so check before ordering.
Is Denso a good brand for oxygen sensors?
Denso is an original-equipment supplier to several automakers, so its sensors use the same connector and fit standards as many factory parts.

An oxygen sensor socket or a wrench that grips the hex is the usual tool. Soaking the threads with penetrating oil beforehand helps on older, rusted sensors.
