Hey all, I have a 98 Maxima SE with LEather, I can't find the sensor that is triggering the 0401 code! It's supposed to be connected to the airbox that I removed to put the K&N on, right? If not, I can't, for the life of me, see anything that is disconnected, dangling, or missing. The boost sensor is dangling, but that's not it, right!? PLEASe, any help would be greatly appreciated. Thanks.

 

Air Intake Temp Sensor code.

That sensor is located in the intakes mid pipe right on the turn where it enters the air box. If you've removed the pipe, chances are your sensor is still in the old tube and the plug is just hanging in your engine compartment.

Reconnect the sensor and place it near the new intake filter.
