Camshaft position sensor location

Hey everyone, I'm new here, and have owned Toyota trucks my life.

I own a '06 Tacoma TRD Sport. It has 310,000 miles on it. Original clutch and throw out bearing.

My check engine light came on and the code is telling me that the camshaft position sensor is out can someone please tell me where they are located. Thanks in advance. Ty

Thank you. That helps a bunch. Ty

 

If it's a p0340, it may have a stretched timing chain given the mileage.

 

P0016 error code is usually a dead giveaway that the main timing chain is stretched on the 1GR-FE engine. This can be confirmed by removing the 4-bolt tensioner cover on passenger side front of the engine and examining the tensioner piston extended length. If it's more than ~5/8 inch, the chain is stretched.

 

Code was a p0012.

 

P0012 seems to point to the Oil Control Valve for Bank 1 (passenger side) malfunctioning according to the service manual, here's a snippet:
-------------
These DTCs indicate that the VVT controller cannot
operate properly due to OCV malfunctions or the
presence of foreign objects in the OCV.
The monitor will not run unless the following conditions are met:
- The engine is warm (the engine coolant temperature is 75
°C [167°F] or more).
- The vehicle has been driven at more than 40 mph (64 km/h) for 3 minutes.
- The engine has idled for 3 minutes
--------------

The oil control valve is easy to remove, no need to pull the intake manifold or throttle body. Just remove the induction tract including the air filter housing and it's right under the throttle body. One electrical connector, one bolt, blow or brush any debris away from it to prevent it from falling into the engine, and wiggle it out. The description sounds like debris is preventing the OCV from closing fully.

 

Ya I cleaned the filters out, and the camshaft position sensors off. Could not pull out the ocv. They seem to be stuck good. Do you have any tricks?

 

Shoot WD-40 around the base of the OCV to lubricate the o-ring. Rotate/twist the OCV back and forth to break the seal of the o-ring against the cylinder head bore, then lift the OCV while continuing to twist it.

 

P0012 is specific to the passenger side head, no need to work on the driver side. What did you find in the OCV filter and on the cam position sensor...any sludge?

And be careful reinstalling the OCV filter...slip it onto the plug and then install both at the same time. Don't install the filter by itself and try to install the plug separately or you risk crushing the filter.

 

Dirver side filter was worse then passenger side. Both positions sensors had a bunch of sludge. If I pull one I'm going to do the other. Thanks for the info.

 

Good luck and keep us posted on your findings. I'm fighting P0016 here and the chains are elongated from poor oil change maintenance by the original owner...25k average oil change intervals. Sludge was in the OCV filter on driver side head, but not completely blocked. Sludge accumulation in the valve cover area was noticeable, but not terrible. The chains just seem to have worn and elongated.

 

Ya it's never been done. 310000 and this is the biggest problem that I've had since I've bought the truck new.

 

You could take the inspection plate off and look at the tensioner/plunger depth. I'm curious as to how much stretch is in a 310k timing chain!

 

Hope you'll keep us updated on your progress...there's not much info posted on P0012 and your findings will be helpful.

 

Subbed for a Pending P0012 code
Truck is a 2006 Sport 6MT @ 300,000 KM, engine was swapped by PO with an '07, which has shy roughly 135,000 miles.
I'm going to attempt pulling both sides sensors.. Quick clean, reset the computer and see what happens.
@Ty4X4 did you resolve your CEL?

 

I put new ones in today. I will see if anything pops up. Both broke when I tried to get them out. Had to use an ez out.

 

Huh, I had an easier time, but I might back out the bolts and dab some anti-seize for future servicing.
I have nightmares about breaking bolts on the engine.. Seems everything else I work on bolts break off, but so far I've been cautious enough to avoid it in the engine bay.

my vvt sensors were gunked up, but I have a hard time thinking it'd effect the funtionality, pretty sure it's just a magnet that senses the cams.
Sensor:

Sits in here and tells the ecu whats going on


But I cleaned it up, had to take it out to get to the OCV anyway. Which was tough to get out, but I used a small pair of pliers between the case and bolt bracket for leverage while supporting the back of the OCV unit, and it popped out pretty easy.

Remove bolt:


use the bracket as a leverage point:



OCV seemed fine, couldn't get to the filter, and didn't want to try poking any tools in there, but it visually looked okay, oil was clear.

I'm letting some JB weld cure on another patch job, but Ill take it out and see if the pending p0012 is still lurking..
This was for bank1, but bank 2 is 4 inches to the right, probably necessary (or much easier) to remove the throttle body to get to.

Will update after a short cruise.

 

Figured there had to be something up with the OCV filter, as everything seemed okay with the camshaft sensor and OCV..
This job sucked..
Not sure if having a CAI made it this much more difficult than it seemed for others, or what, but at no point could I see what I was doing.. Shove a phone down there, take pictures, and feel around till I found the bolt. In hindsight, removing the CAI would have made it much easier, but my winch solenoid is mounted to the air dam, and that was 2bolts more than I felt like dealing with.... ......

The OCV filter bolt is at the same level as the header. 14mm, right behind the dipstick, installed at an upward angle.




The pink is my coolant resevoir, for reference, and the ratchet is on the bolt...

The filter did not come out with the bolt, and I broke one of the tabs off trying to coax it out.. I read elsewhere on here that you could just pull it out with tweezers.. Perhaps with a shrink-ray.. Definitely want to take your time with this, getting mad doesn't help..


It was all pretty black and gunked up here, but I cleaned it off real good, re-installed, and went for a good long rip.



result:
No more P0012 lurking..

Just my HO2S codes sitting in the pending file, waiting to ruin my day..

 

Did head gasket job . Heads and valves milled 5thousandths. Now have p0012 code .changed the ocv .Still have code. -__-.
