Would you know the product code of the Engine Coolant Temperature Sensor for the my car? At Advanceautoparts I bought the ECT sensor with a product code WT5009 and it is not the same fit. They asked me if this is for the computer system or the cooling system.

I cannot find that code. The ECT sensor at Advance Auto Parts that I bought has a code of WT5009 which does not fit and the other one that I searched online was WT680.

Those are the different companies part numbers they use for their systems, the actual OEM Honda part number is what I listed last post.

Please see encircled item on the photo. Is that what I need to replace when my radiator fan is still on even after the engine is off and I noticed a decrease in engine power as well as increase in fuel consumption? Thank you for the help and what tool will I need to replace it? Thanks again.

No, faulty radiator fan relay would be the cause of that issue.
