Does the Denso 234-4441 fit my vehicle?

It is a specific-fit sensor for listed applications, including 2013-2019 Cadillac ATS, 2019 Cadillac CTS, Chevrolet Equinox and GMC Terrain upstream positions. Check your engine and sensor position against the fitment list before ordering.

Is it a direct replacement for ACDelco 213-4574 or Bosch 16132?

Yes. Denso lists both as cross-references for the same applications, so it can replace either where those parts fit.

Do I need to splice wires to install it?

No. It comes with a 14.76 in. harness and a male connector that plugs into the factory harness.

No. The sensor has a threaded 0.708 in. body but no bung is included, so a stripped or damaged bung needs separate repair.

Will it fix my check engine light?

It fixes codes caused by a failed sensor. If the fault is in the wiring or the catalytic converter, replacing the sensor will not clear it.

Yes. It is a heated 4-wire sensor with a 0-1 V output range, which helps it reach operating temperature quickly.

About the Denso 234-4441 Oxygen Sensor

The Denso 234-4441 is an OE-style heated oxygen sensor made as a direct replacement on select Cadillac, Chevrolet, Buick, and GMC vehicles. It has a 4-wire design with a male connector and a threaded, thread-in mount. The wiring harness is 14.76 inches long.

The sensor uses an aluminum oxide trap layer that helps protect the ceramic element from silicone and lead contamination. It is built to match original equipment requirements for fit and performance. It supplies exhaust feedback for fuel control and emissions systems.

This is a specific-fit part, so the vehicle year, make, model, and upstream or downstream position must match. Before installing, check the connector style, wire count, thread diameter, and sensor position. Inspect the harness routing and exhaust threads as well. The part cross-references ACDelco 213-4574 and Bosch 16132 for the same application.
