Bosch 13055 oxygen sensor for the 1996-1999 Saturn SC1 4-cylinder 1.9L and other vehicles measures the air-fuel ratio in the exhaust and reports it to the ECU. It is a downstream, heated, switching-type narrow-band sensor.
- Heated narrow-band design with an integrated heater element
- Reaches operating temperature in less than 10 seconds for a fast signal to the ECU
- Metal housing with TSP coating to resist vibration, corrosion and contamination
- Built for exhaust streams up to 1,880°F
- Advanced ceramic elements and optimized heater control for steady performance under thermal and vibration loads
Quick facts

A check engine light, rough running or poor fuel economy can come from a worn oxygen sensor, but those signs have other possible sources. With the engine off and cool, look over the sensor wiring and connector for cracks or burn marks, and have the codes read to find the cause before you replace it.
Fits
This downstream sensor is a direct-fit replacement for the 1996-1999 Saturn SC2 4-cylinder 1.9L and the 1996-1999 Saturn SL 4-cylinder 1.9L; each takes one, and this listing is one sensor. If your Saturn is not named here, find its model and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right Saturn SL oxygen sensor for the 1996-1999 4-cylinder 1.9L?
Yes, Bosch 13055 fits the 1996-1999 Saturn SL 4-cylinder 1.9L and the 1996-1999 Saturn SC1 and SC2 4-cylinder 1.9L; each takes one. For another Saturn, look up its year and engine in the "Vehicles it fits" section.
Does this Bosch premium oxygen sensor include the wiring harness?
Yes, Bosch 13055 comes with its wiring harness. A mounting bracket is not included.
Is this Bosch O2 sensor heated?
Yes. This downstream sensor is a heated narrow-band type with an integrated heater element and an M18 - 1.5 thread.
Is anti-seize already on the threads of this oxygen sensor?
Yes. The threads carry pre-applied conductive anti-seize, and the direct-fit connectors are made for quick installation.
How fast does this oxygen sensor heat up?
This sensor reaches operating temperature in less than 10 seconds. That gives the ECU a quick signal for closed-loop control and cold starts.
