It is the connector with the blue casing. This part keeps clicking while the engine is running and after the engine is turned off. Also, the check engine light comes with every click. Can anyone tell me what this is?

Thanks

 

Looks like a pressure exchange solenoid. Not sure of the exact name, but hope that helps.

Thanks,

Thanks. I will look into it. If that is what this part is, would it cause the car to bog down and stop running?
