The primary Oxygen sensor is screwed into the exhaust manifold at the point where all 4 chambers dump into the headpipe. It's the only component on the exhaust manifold that's connected to wiring.

There should be a second oxygen sensor after the catalytic converter, but they seldom fail.

Where is the O2 sensor located on a 1994 Saturn SC1?

O2 sensor is located in the exhaust manifold just off the front of your motor. If you open the hood and locate your exhaust manifold, follow it down toward the radiator. you should see a 1-wire sensor sticking out of the exhaust manifold. this is your O2 sensor. you will need either a special Oxygen sensor removal tool, or a 7/8 wrench to remove it.

there are two O2 sensors on this vehicle. one is located just under the hood. if you follow the exhaust down from the front of the engine, the sensor is screwed right into the manifold. the second sensor is under the vehicle just after the catalytic converter.


Will bad o2 censors prevent your Saturn Ion from starting?

Yes, a malfunctioning oxygen (O2) sensor can potentially prevent your Saturn Ion from starting, particularly if it leads to a significant fuel mixture imbalance. While the car may still start in some cases, a faulty O2 sensor can cause poor engine performance, increased emissions, and trigger the check engine light. It's advisable to address any O2 sensor issues to ensure proper engine function and reliability.


Where is the downstream o2 sensor located on Saturn outlook?

The downstream O2 sensor on a Saturn Outlook is located in the exhaust system, specifically after the catalytic converter. It monitors the efficiency of the catalytic converter by measuring the oxygen levels in the exhaust gases. To access it, you'll typically find it mounted on the exhaust pipe, just before the muffler.


Do you need upstream or downstream oxygen sensor?

Depends on what the problem is or what code was set.
