Give your engine computer accurate exhaust-oxygen readings with this Delphi sensor, the ES20316 oxygen sensor, which is tested and calibrated to OE standards. It fits many vehicles, among them the 1990-2003 Ford F-150 4.2L / 4.6L / 4.9L / 5.0L / 5.4L / 5.8L, 1995-2010 Ford Explorer 4.0L / 4.6L / 5.0L and 1991-2010 Ford Mustang 2.3L / 3.8L / 3.9L / 4.0L / 4.6L / 5.0L / 5.4L, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list.
An oxygen sensor monitors the oxygen content of the exhaust stream and reports it to the engine control module, which uses that signal to help manage the air-fuel ratio. Delphi is a global OE manufacturer of oxygen sensors and builds this unit to its own OE standards.
- Planar technology: Delphi's planar technology also covers older, conical-design sensors. Its smart design consolidates part numbers without relying on long wires.
- Protective coating: A patented coating on the sensor helps prevent contamination.
- Fuel compatibility: Validated for all fuel types, including ethanol blends such as E85.
- Durability testing: OE tested to 150,000 miles, plus 2,000 hours of severe thermal testing.
Depending on the vehicle, this sensor is cataloged for the center, front, front left, front right, rear, rear left or rear right position. The "Vehicles it fits" section shows the position for each application. Listed applications use one or two of these sensors depending on the vehicle and engine. The package contains one oxygen sensor and an instruction sheet. Country of origin: Belize.
Frequently Asked Questions
Which vehicles does the Delphi ES20316 fit?
It fits the 1990-2003 Ford F-150 4.2L / 4.6L / 4.9L / 5.0L / 5.4L / 5.8L, 1995-2010 Ford Explorer 4.0L / 4.6L / 5.0L and 1991-2010 Ford Mustang 2.3L / 3.8L / 3.9L / 4.0L / 4.6L / 5.0L / 5.4L; see the "Vehicles it fits" section for more.
Is a Delphi lambda sensor the same as an oxygen sensor?
Yes. Lambda sensor is another name for an oxygen sensor. It monitors oxygen in the exhaust and signals the engine control module, which uses that reading to help manage the air-fuel ratio.
Which sensor position does the ES20316 fill?
Depending on the vehicle, it is cataloged for the center, front, front left, front right, rear, rear left or rear right position. The "Vehicles it fits" section shows the position for your application.
What comes in the box, and how many do I need?
The package contains one oxygen sensor and an instruction sheet. Listed applications use one or two of these sensors depending on the vehicle and engine.
What are signs an oxygen sensor may need replacing?
Common signs include a check engine light, reduced fuel economy, a rough idle or a failed emissions test. These symptoms can have other causes, so diagnose the fault before replacing the sensor.
