Resolved where's the coolant sensor? for error code 21

[wolf alchemy]

I just bought the coolant sensor and it isn't even a direct plug in. Help.

If you are getting a code than it is the one for the ecu. The one in your hand on the left is for the ac system. The new one that you got is wrong, that is common for the parts stores to give the wrong one. There are 3 on the thermostat housing. One for the ac, one for the ecu, and one for the gauge. You need the lower one with 2 prongs on it. Which parts store are you shopping at and i can give you the correct part number for the correct part. Also take into consideration that it could easily be the wiring, it is real common to have bad wiring in the pigtail.

Check the wiring before anything. What i got is SU306 for the temp sensor for autozone parts. For oreilly parts it would be WT3005

Looks like the ac switch the cts should be a t fitting.

It's cool now since I know what's up. I'll post an update if its fixed.[DOUBLEPOST=1411058738][/DOUBLEPOST]Update. Is this correct? The yellow is on the center prong, and the green wire is on the outside prong.

This is my first post, I hope you guys can help me.
I am getting a DTC 21. I know that that is the code for the ECU coolant temp sensor. I see what I need from the pic at the top, but my local parts house(advance) can not seem to get me the right part. Does anyone have any part numbers for the sensors listed in the pic up top? Even if they are not part numbers from Advance I can cross reference them and hopefully get the correct parts.

Here you go.

I recommend this with it.

Thanks edged. I will get those ordered right away. Would you happen to have a part number for the AC sensor that is on that housing as well?
