Can bad spark plugs cause O2 sensor code?

Rough Idle

When a misfire occurs due to bad spark plugs, the unburned fuel may trick the O2 sensors. The O2 sensor will then regulate the fuel mixture and you may get a lean mixture. This can cause rough idle and even more misfires on other cylinders.

What is the code for a bad oxygen sensor?

Once the oxygen sensor stops performing as intended, the vehicle computer detects that and turns on the Check Engine light. This will usually have a diagnostic trouble code (DTC) of P0138.
