Take off the two covers on top of your engine. The ECT sensor should be on your right side of the engine. It may be either black or green and has a 4 blade connector. There is a plastic clip you slide out to replace the sensor. Hope this helps. Only takes a few minutes to replace

Usually it's on the cylinder head, take a look around for a sensor screwed into the engine block or cylinder head with two wires coming out of it. Full details on the ECT sensor and a how-to video here - http://www.obd-codes.com/faq/ect-sensor.php

2004 Volkswagen Jetta 2.0 non-turbo. My MK4 VW shows P2177 and P3211. Help!
Question edited for clarity and toss in some CAPS.
Question moved to model category.

P2177 is Fuel Air sensor showing Lean mixture, so it is dumping more fuel and sooting up plugs and the catalytic converter. After fixing, you will need a system cleaning additive.

Location of the ect sensor
It's just to the drivers side of the valve cover. Attached to the coolant flange under the hose for the PCV. In this pic if it works.
