Description

Keep closed-loop fuel control reading accurately with the Delphi Oxygen Sensor ES10951. It installs as a direct-fit replacement for the 1990-1993 Mazda Miata, threading into the exhaust to restore the feedback signal your engine control module relies on.

Measures exhaust oxygen: the sensor reacts to the oxygen content in the exhaust stream and sends a corresponding voltage signal back to the engine control module.
Supports air-fuel management: that signal is what the ECM uses to trim the air-fuel ratio during closed-loop operation, helping the engine run at its intended mixture.
Direct-fit replacement: designed to replace the original oxygen sensor on the listed application.

A worn or aged oxygen sensor can produce a lazy or out-of-range signal. Signs this part may need replacing include a lit check-engine light, rough or uneven idle, and reduced fuel economy — diagnose the cause first, and if a failed oxygen sensor is behind those symptoms, this ES10951 replaces it.

What vehicle does this oxygen sensor fit?

It is a direct-fit replacement for the 1990-1993 Mazda Miata. Check the "Vehicles it fits" section to confirm it matches your vehicle before ordering.

What does an oxygen sensor do?

It reacts to the oxygen content in the exhaust and sends a voltage signal to the engine control module, which uses it to adjust the air-fuel ratio during closed-loop operation.

What are signs my oxygen sensor may need replacing?

Common signs include a check-engine light, rough idle, and reduced fuel economy. These can have other causes, so diagnose the fault before replacing the sensor.

What part number is this and what does it replace?

This is Delphi manufacturer part number ES10951. It cross-references numbers such as 234-1024, OS2074, OS700, 12113, REA1460, SG649 and more listed in the Interchange section.

Will replacing this sensor fix my check-engine light?

If a failed oxygen sensor is the confirmed cause, installing this ES10951 replaces it. Other faults can trigger the same code, so diagnose the cause first.
