2006 Honda odyssey 3.5 L cam sensor location

3.5 L VTEC cam sensor location

This process took me at least 7 hours to do as it was trial and error getting the Camsensor and bolt back in, not easy to turn!
I had one heck of a time getting my bolt out AND pulling the sensor.
But the worst part is trying to put the New Cam sensor and bolt back in! ALSO. Make sure you stuff a rag down there as you WILL drop the bolt. I did and event though I had a magnet could not find it. Once I put in the rag though, It made finding the bolt SO much easier, so do NOT skip this step! Stuff a Rag down there and have a antenna type magnet so you can get that bolt.
(I bought 4 extra 8mm little bolts 3/4" long from the hardware store before I even started this, as well as the 12mm 3" bolt mentioned below)
The Suggestion of taking out the two 12 mm bolts didn't go far enough for me. There simply STILL was not enough room to replace the Cam Sensor and tighten the 8mm bolt.
I needed to also loosen the CAM Bolt and pull the CAM Pully out somewhat so I got even more room.
What I did was take the 2 12 mm bolts out, AND INSTALL a LONG (3") 12 mm bolt and hand threaded it in so if I loosened the cam bolt and pully too much, the CAM would not lose timing and would stay in place. I needed to loosen the CAM Bolt and CAM so I could pull the plate out further. That LONG 12mm bold was my safety bolt in the event I loosened the cam bolt and pulled the CAM Sprocket too far out. Fortunately I didn't and therefore kept the timing belt in time, if that makes sense.
BEWARE if you loosen that CAM Bolt too far and pry the CAM too far, you'll be resetting the timing belt! (I think I went out maybe 4-5 full turns, then pried the pully.
I have bragged how Honda's engineers always made it easy for the Mechanic... But not in this case... Putting it back in place was the WORST Part! To tighten the 8mm bolt on the Cam Sensor I used an 8mm Combination wrench after MANY trial's and errors! AND that was Angling the closed end of the wrench to get it to tighten the bolt. Good Luck and Be Careful, and BEWARE IF you're gonna pull that cam pully bolt for more room!

I have the same enquiry . My code is for Sensor A. apparently thats bank 1 which is the rear cylinder head and what he was working on was at the front .There must be more than one but I found no info on any others apart from this front one in this video
