How do you reset the computer after changing 02 sensor on a 1998 Chevrolet Prizm?

A 1998 Chevrolet Prizm doesn't have a "reset" button like some newer cars do for things like oxygen sensor replacements. The car's onboard computer (Powertrain Control Module or PCM) will automatically relearn the new O2 sensor's values. This process happens as you drive the car.

To allow the PCM to adapt:

* Drive the vehicle for a reasonable distance (at least 50-100 miles) under varied driving conditions. This means highway driving, city driving, and some acceleration. This gives the PCM enough data to adjust its fuel mixture based on the new sensor's readings.

* Avoid aggressive driving immediately after the replacement. Extreme acceleration or hard braking might confuse the system during the learning period.

* Check the engine light. If the check engine light (CEL) remains illuminated after a substantial driving distance, there might be another issue besides the O2 sensor. You'll need to have the codes read using an OBD-II scanner to diagnose the problem.

In short: There's no manual reset. Just drive the car normally for a while and the PCM will automatically adjust. If the problem persists, further diagnosis is needed.
