02 sensor?

[Cody Ducusin]

In a few days I’m gonna install a K&N Blackhawk CAI and a Borla Exhaust. Has anyone had any problems with intake/exhaust causing the check engine light to go on? Typically 02 sensor related? If so what can be done to prevent this or would I have to take it to the dealership to recalibrate my computer?

I haven't seen any reports of the issue so far on the internet.

Your O2 sensor isnt connected to your intake so you should be fine. never heard of that being an issue.

Thank you Rob and Malcom. Installed the CAI and exhaust last week and so far no issues. I only asked because I had some friends tell me that it could be an issue. They’ve had that happen on their older Tacomas I believe 2nd gens, Never asked much about why or how.

O2 sensors are before and after cats , changing exhaust will not effect the o2 sensors, unless you replace or remove cats

Say you did remove the cat short of a tuner how would you go about stopping your truck from popping a code... I thought about 90 degree adapter
