2002 taurus

Hello,

I have an 02 tarus that has a squeel to it. I found that it comes from an aluminum looking piece attatched to the air filter tube; it attatches to the intake. It has the accelerator cable attatched to it. Any idea what the name of this part is? I have asked around and nobody knows. Being a do it yourselfer, I would rather not take it to a shop.

Thanks!

Does it sound like a sqeaking belt except you can hear it on the drivers side of the engine (chirp, chirp, chirp, chirp)?

If so I would bet that you are hearing the CMP shaft which is located right underneath the area you are talking about (3.0 Over Head Valve "OHV" v-6 engine).

The piece that the throttle cable is attached to is called the throttle body.

Is it this part? This is the Idle air control motor ( IAC)

Or this part? This is the cam shaft syncronizer

[bigdaddyof3]

You are correct!

[Jeremy airjer W]

The first one drove me crazy, the second one took me a couple of minutes to remember, by the third one I was diagnosing them as they pulled into the lot!

[bigdaddyof3]

Not to sound stupid, buy what is the cmp shaft?

Thanks

[Scott K]

Cam shaft position sensor syncronizer shaft. It sits in the distributer hole and spins with the engine, and the cmp sensor tells the computer what position the camshaft is in.

[Jeremy airjer W]

Think of it as a distributor with the top cut off.

Hi there,

Someone said that it was the cmp shaft that actually needed to be replaced. Any idea of an average labor for something like this? I see the part is about $35 on the napa HSOforum.

Thanks

[bigdaddyof3]

Thank you

[Jeremy airjer W]

The shaft is only available from the dealer as far as I am aware. It will be more than $35 which is probably the cost of the sensor. There is a fair amount of labor involved. The plenum has to come off and the wiring harness needs to be moved aside just to gain access to it.

[Scott K]

And you need to make sure it is timed correctly.

I have seen after market syncronizers available.

[Jeremy airjer W]

Exactly! Its just like a distributor and needs to be timed. In a pinch, once access is gained and the sensor is removed, the crank can be turned until the center part of the shaft lines up with the notch on the outer shaft. Install the new one in the exact same position and it will be pretty close. You'll know if your to far off if the check engine light comes on immediately. At that point you'll need to take everything back apart and align it with the tool.

[bigdaddyof3]

Ballpark estimate?

[Scott K]

The book shows oe part cost $128 + labor at 2.8 hrs x whatever the labor rate is at.

[Jeremy airjer W]

+ the o-rings for the plenum.
