Hey guys I have 2006 Chevy Cobalt 2.2 and my engine light came on and had it scanned and the code came up as Camshaft Position Sensor and I was just wondering where it is located. I did call the dealership and all they told me was that it is located in the center and on top of the engine. If you know where it is please let me know thanks guys!!!

its on the end of the cam... the exhuast cam on the lsj. on the drivers side of the block... dont know if its different on all the 4cyl

All I could find on the cam sensor was ...

"the cam sensor is located on the driver's side at the rear of the engine...it's butted up against the engine pretty much....look for a cylindrical aluminum housing above the thermostat housing...that's the camshaft position sensor housing....it's bolted to the back of that"

I took a look and the only thing I could possibly see him talking about was this..



But I've never seen a cam sensor in a housing before.

Thanks for the response guys I have on more question do I need to take off the heat shield from the exhaust manifold to get to the camshaft position sensor?

the camshaft position sensor was added on 07+ model years you should not have one 03-06 l61 only have a 24x reluctor wheel on the crank. the peace in the pic is the power steering block off plate left over from the cavalier and I have know idea about the code

You don't have a camshaft position sensor.

Who scanned it and using what? The exact code would be helpful.

Thanks j27-2. Was trying to figure it out for a bit today, but there were quite a few different places people had said it was located at. different models I suppose.
Hope you figure your **** out Rjared

Ok I am freakin Confused guys!!! I called the dealer and they told me that my 06 2.2 cobalt does have a camshaft sensor!! What I am going to do is pull the picture from this forum and try to find it.

Seriously... Get the car scanned and post the code here. It will start with a P and have four numbers following.

With that we'll know more.

stinkyfisherman

The code should be P0340.

I'm having the same problem on my 05. I think it might be my plugs though, I put the e3 plugs in and sense I did that the code has been showing.


From what I have found at least on mine is that I dont actually have a camshaft sensor its all done my magic from my ICM and Coil pack.

RacinJared

Yeah I have E 3 spark plugs also I am thinking about taking them out and putting the standard Ac Delco plugs back in and seeing what happens. I did check with the dealer and they told me that the 2006 chevy cobalt LT doesn't have a camshaft but all the camshaft motions go through the ICM. So I am going to try that and see what happens. Also I know this is random but how many catalyic converters does the 2006 chevy cobalt have? I happend to look under my car and and it looked like I have two of them. One is about a 12 to 16 inches back from the exhaust manifold and the other is on down the exhaust. I may have a C02 sensor out maybe but not sure. But thanks guys for your help I will keep you all updated and I will also get the code four you all.

Get rid of those E3 plugs asap. The engine is not designed to run on those plugs. Switch back to AC Delco Iridiums for best performance, longevity, and fuel economy.

This really confusing the h*ll out of me. 06 L4 2.2 ecotec engine with a code of p0341 camshaft sensor. What is actually the scoop? What am I to look for? At the end of the head is a round housing. Is this what I'm to open to find the part that I need? Whats being said is really confusing. Looking at the picture above, is this where I can find the part I need?

...Did you read the thread? You DO NOT have a cam sensor. Assumption would be OP got rid of E3 plugs and everything returned to normal, so your plugs could be bad

T-Kat

Ok, the plugs I have are bosch double platinum. I bought the car used, with it only being 2 yrs. old.
I purchasd these plugs right as soon as I bought the car. Never had a problem, car started every time with just a quick twist of the key. Why would everything go bad now? I don't want to put all this money into the car for I do not have a unlimited amount of money to put into this car. The plugs where fouled on no.1 & 4. 2 & 3 where clean. Ran Crappy as H*ll. Why would changing the plugs make the difference?

ECaulk

They're double Pt not Ir like they should be. You've driven how many miles over 2yrs that would explain the going bad now. Plugs are about ~30 (get AC Delco Ir plugs they cost more but are what the engines are designed for) and a gap checker is ~1 make sure the new ones are gapped correctly.

I'll give it a whirl, I just have my fingers crossed that this doesn't
turn out to be gremlin. Thanks

I have a 2006 Chevy cobalt LS and the codes it threw out were P0340 and P0341 which indicate an issue with the Camshaft sensor. From what I have read, this year of cobalt does NOT have a camshaft sensor? Any ideas why it would throw out that code and why auto parts sites allow you to order a camshaft sensor for this year Cobalt?

Also, the spark plugs, boots and ignition coil have all been replaced and the car is still spitting out these codes

Chulachaser

I also have a P0341 code and can not figure out a solution. I have replaced the ICM, the coil pack, and it has fresh plugs. But the P0341 code is still there after erasing the codes several times over. I dont know what else to do at this point. Any help would be appreciated. Thank you.

You should make anew post about your issue, also I see your title is 2004 Chevy Cobalt...... they started in 05.

Chulachaser

ok I will repost.rem actually cross referencing for a saturn ion. At anyrate, the cobalts have the same engines and therefore same problems. But I'll keep the 2005 in mind. Thanks.

I was able to order a cam shaft sensor when I first started this dead end deal ! Then after finding out I guess rhisv2.2 doesn't have a camshaft sensor.... I even asked the Chevy dealer.. an that's what they said as well...

Can't smog with engine light on.. after I replace a oart..light goes out.. after drive cycle (which is ridiculously hard to get done living in the sticks.. here.. mountain roads etc.. ) after I do manage to complete it so I can get monitors all ready for smog.. after shutting it off.. . next time I start it.. I'll drive about 800 to 1000 ft an engine light back on! P0340 !

I've replaced the spark plugs, coils .. crank shaft sensor ..

purge valve..an the ICM.

So..if what some say is true an this car doesn't have a cam shaft sensor.. how is it the engine light keeps basically saying it does? And if it's some kinda issue.. I would think a recall would have been in order?!? I don't know what to do about a problem part that I can't fix cuz my cat doesn't have the part on it to fix!! WTH 🤪🤔

I'm just bout to give up an just push it off a cliff..!!

if anyone has a solution to my issue..or answers questions..or u can put some clarity to my confusion.

. or maybe u know of a cliff.🤪. please don't hesitate !!

Your help is greatly appreciated !!

thank you

🙏🙃🙏

🤞🤞🤞

I didn't see an answer for the question that was asked above... do you have to remove the heat shield to get to the camshaft sensor??
Thank you

greeniizz

I Also have code 0340 that keeps coming up.. I've been trying to get this car smogged for a couple months now! An I'm bout to just push it off a cliff!!
Iive called..asked.. researched..been to dealer.. forums..auto parts stores.. u name it.. an I still have no answer to what am I suppose to do with this car that the error code 0340 which refers to the camshaft sensor .. when half the answers I've gotten say this 2006 cobalt 2.2 doesn't have a camshaft sensor! Yet I have a new one to replace the old one that's not there? Yet the car keeps saying there's an issue with it?! WHAT THE?:''!(?((;'+!!
I've replaced the crank shaft sensor..the purge valve.. spark plugs..coils..an now the ICM..
Everytime I replace a part the engine light goes out..then I manage to actually get the drive cycle completed (an living in the sticks- finding roads to do this is more than a challenge to say the least!) 🙄
Anyways . After that's completed.. I think I'm just about ready for smog cuz it might stayed out drive cycles done and then I'll shut the engine off go turn it back on a few minutes later drive maybe $800, 000 ft and be on the engine light will come back on error code 0340 and now I'm right back to square one again with having to figure out why that's coming on and the drive cycle and all that so I can get this beast smogged or I'm going to push it off the cliff tell someone has clarification to my confusion answers to my questions or know of a good Cliff let me know I appreciate your help thanks

What plugs and ICM did you install? OEM or the least expensive you could find on amazon? I've had issues with less expensive control units failing out of the box or after a few drive cycles

I found this from another forum, might be helpful:

This ignition system does not use a conventional camshaft position (CMP) sensor that detects valve train position. The ignition control module (ICM) detects when #1 or #3 cylinder has fired on the cylinders compression stroke using sensing circuitry integrated within each coil. The sensing circuit detects the polarity and the strength of the secondary voltage output. The higher output is always at the event cylinder. The ICM sends a CMP signal to the engine control module (ECM) based on the voltage difference between the event and waste cylinder firing energy. This system is called compression sense ignition. By monitoring the CMP and crankshaft position (CKP) signals, the ECM can accurately sequence the fuel injectors. If the ECM does not receive a CMP signal from the ICM, DTC P0340 sets.

More info:
Action Taken When the DTC Sets
• The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.

• The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.

Conditions for Clearing the MIL/DTC
• The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.

• A current DTC, Last Test Failed, clears when the diagnostic runs and passes.

• A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.

• Clear the MIL and the DTC with a scan tool.
