Installation Notes and Tips

Verify the connector style, wire count, and sensor position before ordering. This Denso 234-4078 uses a threaded mount and a female connector, so it should be matched to the original sensor configuration on the vehicle. Confirm whether the application is upstream, downstream, or downstream rear, and check any notes for California or ULEV-specific coverage before installation.

Quality Assurance

Denso manufactures and tests this oxygen sensor to OE standards for fit, function, and durability. The aluminum oxide trap layer is used to help shield the sensing element from silicone and lead contamination, supporting stable operation over time.
