As stated in title, I have an 01 Civic EX, and 1.7 Vtec and snapped a sensor that I cannot find what sensor it is. I checked online, my shop manual to no avail.

Its near the thermostat housing, slightly below valve cover, just above water pipe from back of engine. Yellow/blue wiring. Only numbers are 4041 on sensor. See pics:



I have a check engine light and this is probably the reason so I'm just trying to figure it out. Can't find a breakdown for it either for some reason. Thanks!

 

Looks like the water temp sensor to me

 

Me too. Water temp sensor part #17 (Honda Part# 37870-PLC-004) in this diagram: https://parts.sonshonda.com/showAsse...modelYear=2001

 

That is the VTEC oil pressure switch.

 

My mistake, it is the VTEC oil pressure switch - part #12 (37250-PHM-003) in this diagram: https://parts.sonshonda.com/showAsse...rimLevel=24777
