Hello, I have a 2007 G6 2.4L. Lately my car has been bogging down with a loss of power, and doesn't seem to shift smoothly. My friend used his scan tool and said the car was throwing a code for a cam sensor. I then find out that the car actually has TWO camshaft position sensors, yet I can only locate the one right on top of the engine under the plastic cover. The parts store I called is telling me there are two on this car, yet can't tell me where they are located. Does anyone know if there are actually two, and if so, where the other is located?? I great appreciate any responses. Thanks!

Did you ever find out where the second sensor is located? Also does the computer have to have a crankcase relearn when these sensors are replaced? I know on my grand am it has to have one anytime a crank or cam sensor is replaced.

The intake (INT) and exhaust (EXH) sensors are both located side-by-side on the top passenger side of the engine, under the plastic cover.

Replacing the intake sensor eliminated the hard shifting on our 2.4L 2006 G6. Still have a lack of power, though. Engine light is back on, so I need to check codes again to determine next step. Perhaps the exhaust sensor is faulty, as well.

Replacing one of these sensors is a 5 minute job.

I read there is a wiring issue with the sensors.

Follow-up: Cat Conv also needed to be replaced. Remember, by law, emmisions components are covered to 80,000 miles on all cars. Problems resolved.

It's been awhile, but we had to replace several things to get the car going back to normal again. We replaced both cam sensors, and that didn't fix it! We then took it to the dealer and found out that both the injectors and the catalytic converter were bad. The mechanic told me it was common on these that the injectors clog up and go bad and then make the catalytic converter go bad as well. The injectors were no longer under warranty, but the catalytic converter was. The dealer said they would do it all for free though since it was a known issue with GM. They also replaced my intermediate steering shaft for the SECOND time even though the warranty was up on it. I've had SO many issues with this car before 50,000 miles it isn't even funny!

It says right in my owner's manual that the power train warranty is only 5 year, 60,000 miles...and that's what two dealers have told me. Though, I didn't know that the injectors were covered under power train...so apparently they were still covered and they were BSing me...because the car only had like 49,000 when we had this done.

Just out of curiosity where did you find this 100,000 mile warranty info? Only doubting it because, like I said, my manual clearly only says 60,000 for power train.

Here is where I got it. Both are good reads.

Oh ok, so it seems that this is something that GM released after I purchased my car, and it will roll back and be active on my car. Thanks for the information...and that's awesome to know that the dealer was bullshitting me!

Yes, I understand and use Google daily, thanks. My point was my owner's manual that came with the car said 60,000 miles. How was I to know that GM changed it? That isn't something that I would have just though of. haha.

Hey i was wondering did you guys get check engine lights with you camshaft position sensor? Mine isnt on but when i had a problem with a solinoid the dealer said they found a code but i never seen a the check engine light on. I worry that mines is bad in my 06 2.4 because of bad gas mileage and late shifting at times? Im changing my spark plugs later today to try and help my gas mileage and possible loss of power.

This is not advice to the problem, but I also have a 2007 G6 2.4L engine & my engine light is coming on & going off. When the engine light is on the driver's side headlamp goes out. I replaced the lamp because I thought it was blown, a few days later it went out again & I noticed the engine light was on. When the engine light goes off the headlamp comes back on. Also I'm getting a rough bumping shift between gears. I know very little about auto mechanics, but could this be a cam sensor problem?
