Looks like it could possibly be a hose for the HVAC system. Maybe plugs into the back of the intake manifold? How did you find that?

[pmolina0436]

I was changing my knock sensor..but I found it..a hose..riht under the map sensor thanks

Do you have any other pics? If so I can look in the morning to try to help you out.

Yes sir, that looks like the heater control vacuum line. If I remember right it plugs into a vacuum port right above or below the big vacuum line going to the brake booster

Changed my knock sensors the other day. Reset code. And again code came back on 3-days later..I dont hear any rattle or anything. ...motor
feels good except is sometimes boggs(most of the time feels good though)!! They told me its cause the knock sensor might be "adjusting" timing or something. They reset the codes and told me to wait another 2 weeks.

Has this happened to anyone else?

[cammed goat]

Knock sensors don't "adjust" timing. They either pull timing or they don't. What code is it you're getting?

[mark21742]

You have headers and a higher stall right? You might need to get your knock sensors sensitivity turned down SLIGHTLY by a tuner.

I've also seen people use some type of high temp foam that goes under the knock sensor (looks like a big thick washer that goes under the knock sensor with a hole in the middle for the sensors threads to go through)

Yep, Mark's right. Went and looked for it on my 04. Found it plugs into a vacuum block with other lines on the back of the intake. Mine has hose you show connecting to anther small hose going to the vacuum block.

Mine is stuck on default defrost.....so I have to check that same little hose to see if It's broken, or the other end came off under the dash....I dont mine not having my a/c system, but it would be nice to have my dash vents back lol

Knock sensor ban 1 curcuit low input..
Same for bank 2..
Wonder if it could be a wiring isue?? Or fuse blown???

[pmolina0436]

I have headers but stoc stall..I've been running my car like this ith no problems for
Over a 2 years...
I'm think maybe a frayed wire...or a fuse not working properly..
I mean the car feels fine..and I here zero nice from engine..
My guess...electrical....its giving me a circuit low input on both sensors

[mark21742]

Id look for a fraid or broken wire right around the back of the intake before the knock sensor wire goes into the rest of the harness.....there is a lot of heat trapped under the intake where those two wires run
