I am trying to find out the part number for the ECT (Engine Coolant Temperature) sensor for a 2001. hondapartsnow.com has the sensor under Engine -> Intake Manifold, but lists two part numbers 37870-PK2-005 and 37870-PK2-015. Which is the right one, and what is the difference between the two.

Thanks.

 

#29

The "05" part is the o-ring for the sensor. It is included with the part 29.

 

I was going to post a screenshot showing what I mean but when I went to grab the screenshot I see that 37870-PK2-005 is superseded.

29 37870-PK2-005 SENSOR ASSY., WATER TEMPERATURE (HADSYS) Replaced by: 37870-PK2-015 JPN 1 $36.58 $26.52
29 37870-PK2-015 SENSOR ASSY., WATER TEMPERATURE (HADSYS) JPN 1 $36.58 $26.52

I swear it didn't look like that yesterday haha. Thanks for your help.
