2012 Terrain 2.4l Camshaft Position sensor locationsS

There are two Cam shaft position sensor locations from what I read and from what the Autozone computer tells me.

I swapped out the driver side rear by the firewall, but what I need to know is where is the second sensor?

Facing the rear of the vehicle, is it on the left or rear side of the front of the engine?

It might be under something on the from driver side, I would think it would be opposite in terms of position to the one that I already changed out.

Also, I went ahead and changed out both Camshaft Solenoids too, so all i need to do is swap the last Sensor

I found it, it is immediately in front of the one by the firewall

You can reach it from the front driver side of the engine and it is up under the camshaft, you have to take of 2 bolts and one nut, all 10-mm to access it.

Also, my 2012 has 79k miles on it, the Check Engine light came on with the P0010 code so I usually drive my cars to 200k miles so I went ahead and did the 2-solenoids and teh 2 Position sensors

Do a search on I4 engine problems in 2010-2012, may have a timing chain issue too. These engines have a 100K powertrain warranty, the dealer should fix this issue without a charge.

Re: 2012 Terrain 2.4l Camshaft Position sensor locationsS

I'm having similar issues and am looking for help. My terrain is a 2012 2.4L. It has been throwing a p0011 choose on and of four a year or more. I finally changed the cam position sensor the problem is still here and has actually gotten worse. It stalled out on me 8 times last night. The car stalls out at low idle unless you feed it constant gas.

I was also reading around the forums and picked up on that it might be a cam actuator problem. Is this another possibility?

So is there actual 2 cam position sensors? If so where are they located?

I have seen recalls for the 2011 engines
I checked for recalls with my Vin and there was nothing pertaining to this.

Re: 2012 Terrain 2.4l Camshaft Position sensor locationsS

Amazingly, my ESC light went off yesterday after I put some 93 octane gas in and began driving.

There are 2 Cam actuator solenoids on the top of the engine, extremely easy to fix, the time would be 15-20 minutes. (there is a YouTube video for this)

the 2 Cam Sensors are a little tougher only because you have to reach to the rear drivers side of the engine, but I could feel the sensor and took it out with a 1/4" socket wrench and a 10-mm socket.

The front Cam Sensor is under a part on the front right side and you have to take 2-bolts and one nut out/off, then the sensor bolt is under the cam

All bolts are 10-mm and I did it in my derive way on the ground, no ramps etc. Total time to do all of the solenoids and sensors would be no more than 1 hour, mostly because they are in hard to reach spots.


I will preface this with the fact that I have built engines for my corvettes and mechanically inclined, and I aint skeered of no nuts and bolts

When these problems were more prevalent, I thought there was mention of some type of software reset that had to be done after replacing the actuators. Any truth to this, or did you find that just changing them was enough ? BTW, how much were these parts ?

The camshaft position sensors from Rock Auto were $32.xx

The Variable Timing Solenoid (that's what they call it on Rock Auto ) was $30.xx

So $120 and change for all 4 sensors, roughly the cost for the diagnosis at my local Dealer.

I did not go to the dealer, they did not mention a re-set.

I installed the parts and the light was still on after I disconnected the Negative battery cable, then i put some 93 octane in and the lights went out, maybe I got lucky
