Default Driving with missing o2 sensor ?
My truck has 4 o2 sensors and I noticed it’s missing one from the exhaust system.

Can I drive with a missing sensor or will it cause an exhaust leak because of the hole ?

Which sensor am am I supposed to get again ? I know Bosch doesn’t work good with our trucks and idk if any parts store will have the one I need in stock.

I dont care if it affects fuel economy if it’s temporary but if it’s too rich and causes my engine to run like complete **** then I’ll just buy the sensor before I start driving the truck.

Which sensor is missing? Is it the 1st sensor in line after the exhaust manifold or the one behind it? Also, are the threads still there to screw in a new sensor or are those gone, as sometimes the threaded bung comes off that the sensor screws into?

Wher did it go? What do you mean you “noticed” it was missing? The exhaust leak caused by a removed O2 sensor is kinda hard to miss. Did you not wonder why your exhaust suddenly became much louder? Lol

I don’t remember honestly. I don’t have the truck at my house anymore it’s at a buddy’s shop. The thread is still there.

I bought the truck with the tranny out and the exhaust system was in the bed of the truck. There’s only 3 plugged up and I don’t see the 4th.

My truck has 4 o2 sensors
Truck details would help, HD models had four 02's along with California trucks.
