Thread: What is this sensor

There is a sensor on the bottom of intake with 4 hoses running to it. What is it what does it do? because my is disconnected

On the bottom of the intake plenum? On the front or rear of the engine? Highport or lowport?

highport, bottom on the passenger side

Left hand or right hand drive?

Just kidding...


Uhh, sounds to me like the idle solenoid. I looked for a while for a good picture of a highport in that area cut only came up with two links.

It really will help to find out where it's attached.

its the sensor in the lowport pic the one with the hoses are connected to

thats a AABV, or auxilary air bypass valve, according to nissan, it helps with a smooth idle. if it goes bad, usually the car fluctuates idle between 800 and 1200
