Sensor identification

Welcome to 2CarPros.

That's a tough one without seeing it. Is it possible for you to upload a pic of the item in question? Also, let me know if it is a 1.5 turbo, the 2.0 turbo, or the 1.6 turbo.

Take care,
Joe

Welcome back:

The silver item is a High Pressure Fuel Pump. I circled it in your pic. Let me know if that is the part you are referring to and what is loose?

Joe

Welcome back:

It comes as a unit. Here are the directions for replacement. The attached pics correlate with the directions.

Let me know if this helps.

Welcome back:

Is it the connector on the pump or the connector on the wiring harness? If it is on the pump, I can't see how it could be replaced or repaired. It's a molded part.

Let me know.
Joe

Welcome back:

Since it is on the pump, I would replace the unit. I can't see how it can be fixed safely, or even fixed at all. You don't want the chance of an electrical short at the high pressure fuel pump.

If I'm misunderstanding you, let me know.
