ECU indicates front O2 sensor out as soon as I installed AEM short ram intake

[Musthavego]

I installed an AEM short ram air intake and my check engine light came on. The ECU indicates that the front O2 sensor is out. Is this the result of the air intake change or is it just a coincidence? Should I check something else, or just replace the O2 sensor?THANKS!

I should add that it is an otherwise stock 1996 240SX.THANKS!

reset the ecu first. if it comes back, replace the sensor.

Sometimes the ecu will throw codes when you are installing stuff on the car because you forget to disconnect the neg terminal.

I'll give that a try, I appreciate the help!
