Default P0134: O2 Sensor Circuit No Activity Detected

I was climbing a hill the other day over a 250 mile trek and the Service Engine Soon light appears. Took it to my mechanic and he told me it was a P0134 Error: O2 Sensor Circuit No Activity Detected

I didn't notice anything out of the ordinary with the car. It didn't burn more gas, it wasn't missing, nothing.

However when he connects the OBDII and turns the car on he can see that both the O2 Sensors work. He cleared the light and told me to drive it in the hills to see if the light comes back on.

So far..... no light. Should I be worried or could it have just been a glitch?

Should I wait to see if the O2 Sensor triggers another Service Engine Soon indicator or should I just replace it?

You can but if it came on once it'll come back on again. How many miles do you have on the car and what engine do you have?

It has 105K miles with the 4 Cylinder. Had the tyranny serviced at 65K and 95K. Change the oil every 4K miles. Never had any problems with it at all.
