If the plug doesn't match exactly, it won't work, so be careful there.

Now, some quick O2 sensor education: Heated sensors like this one should typically be checked or replaced every 60,000 miles.

If you're replacing one, it's usually smart to do them in pairs since the new sensor works faster than the old ones, which can confuse your ECU and trigger more codes.

Installation tip: If the old sensor is stuck, try an O2 socket with a long ratchet or breaker bar for more torque.

After you get it out, clean those bung threads properly before installing the new one.

Oh, and if you're still getting fault codes after replacement, it might not be the sensor - could be circuit issues, mixture problems, or even a bad catalytic converter.
