2012 Toyota Prius Camshaft Position Sensor TRQ ESA94799

Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

Remove the plastic cover. Cam position sensor is located on the top of the valve cover, underneath the plastic cover. You can do it with the cowl panel installed. We just have it off for other things. It also makes it easier for you to see what you're doing. I'm going to spray the connector with some water displacement oil because it is pretty dirty. It'll help me get it off.

The lock is here on this side. Sometimes you have to push the connector in and then squeeze on the lock tab. Just got to work it back and forth. Try not to pull on the wires. There it is. Put that aside. Going to remove the 10 millimeter bolt holding it in. Use a 10 millimeter socket extension ratchet. Going to wipe up some oil I sprayed in there. Need to remove this. It does have an O ring sealing it, so I got to push it kind of back and forth this way. Break it free, and then kind of wiggle it out of the opening. There it is.

Here's our original camshaft position sensor we took out of our vehicle. And here's our brand new one from 1AAuto.com. Same exact style connector. Same design as the camshaft position sensor. This will fit great and work great for us.

Put the new one back in the same opening as the original one. O-ring might be a little tighter. Push it into place. Reinstall the bolt by hand. Use the steel bolt and aluminum valve cover. You don't want to cross thread it. It should fit in nice and easy. Just gently tighten it. Feel it get tight just stop. You don't want to crack the valve cover.

Reinstall the electrical connector. It's keyed only going on one way. It'll click when it locks in place. Put your plastic engine cover back on. These three rubber mounts just push on over these three ball studs. Apply up on the oil cap hole, and that's it.
