Delphi ES10628 oxygen sensor for the 1991-1994 Saturn SL 4-cylinder 1.9L and other vehicles measures oxygen in the exhaust and sends a signal to the engine computer. As a Delphi oxygen sensor, it is tested and calibrated to OE standards for accurate readings.
- Delphi planar technology covers older, conical-design sensors
- Smart design consolidates SKUs without using long wires
- Patented protective sensor coating helps prevent contamination
- Validated for all fuel types, including ethanol blends like E85
- Tested to 150,000 miles, plus 2,000 hours of severe thermal testing
Quick facts
- Part: Delphi ES10628 oxygen sensor
- Fits: 1991-1994 Saturn SL 4-cylinder 1.9L and other vehicles
A worn oxygen sensor can show up as a check engine light, a rough idle or poorer fuel economy. Before you replace it, rule out an exhaust leak, damaged wiring or a fuel or ignition fault that could set off the same signs.
Fits
The 1991-1994 Saturn SL 4-cylinder 1.9L, the 1991-1994 Saturn SL1 4-cylinder 1.9L and the 1991-1994 Saturn SL2 4-cylinder 1.9L all fit this oxygen sensor, and so do other vehicles. This listing is a single sensor, and one sensor goes on each car. If your Saturn isn't named here, look it up in the "Vehicles it fits" section before you order.
Specifications
