I haven't been on here in years, mainly because I've been driving newer Honda's or could figure out everything myself but this sensor I cannot find.

It's a 2001 Civic EX with 1.7 sohc vtec d-series (don't recall exact engine because haven't had this car long). The one sensor snapped off and I cannot locate which sensor it is. I scoured my shop manual and googled to no avail. See pics...

It's located just below back of valve cover, above water pipe from back of engine. Plug wiring colors look blue and yellow. Only number in sensor is 4041.

Thank you to anybody who knows what sensor this is because I feel like it's probably obvious.

I bet its the solenoid wiring for the spool valve (vtec)

I have a nonvtec in my 01, and a vtec motor from an 04 sitting in my garage.

I can verify if this is indeed a vtec related sensor if needed.

However, I suggest looking up a wiring diagram and seeing if you can verify that as well

It was the Vtec solenoid oil (pressure) sensor.

It doesn't touch too much in the Haynes manual about Vtec specific parts but it randomly dawned on me it was the Vtec solenoid from a Vtec engine I had years back and problem solved.

Thanks all!
