Smile Replaced Control Valve Solenoid 12687167 / Camshaft Position Sensor V6 LGX P0014


Code P0014: "Camshaft Position Sensor Bank 1 Exhaust," first appeared while on a recent road trip, at approximatly 64,000 miles. I was in Washington DC at the time and stopped at an AutoZone for a complimentary scan. As I did not have any noticable loss of power or driveability issues, I continued on my tour. Eventually the CEL turned off and I assumed the issue was temporary. By the time I reached Texas, the CEL re-illuminated and three mechanics advised me to replace the part when I arrive home in NY. They said I may experience a decrease in gas milage and performance. As I continued on my tour, the CEL, again, turned off.

Back home & 6000 miles later:
The day before yesterday, I performed an oil change and used a bottle of Chevron Techron fuel system cleaner, as apart of my routine DIY maintenance. Yesterday, after Goodyear rotated my tires, the CEL re-illuminated. I decided to finally tackle this issue head on. I picked up a resonable $45 OBD scanner from Harbor Freight Tools. The scan presented the same code I was shown in both DC and Texas, "Camshaft Position Sensor Bank 1 Exhaust." I purchased a "Control Valve Solenoid - GM (12687167)"
https://www.gmpartsdirect.com/oem-pa...noid-12687167/ from my local dealer, Atlantic Chevrolet, for $48.56. I discovered Bank 1 is located on the passanger side of the engine through process of elimination. First, I disconected the wire from the visable driver side sensor. Do note, the small wire clip is very tight and required a tool to pull it off but be careful not to pull on the wires themselves! Second, I rescanned with the OBD and read "open circuit bank 2 exhaust." Therefor, I knew I was on the wrong side of the engine. Unlike bank 2, bank 1 is hidden underneath the foam insulation on the passanger side. I could not easily remove the insulation, so I cut a small slit just long enough to access the 10mm nut. I then removed the old sensor/solenoid and replaced it with the new one. The original part did not appear to have any visable damage and perhaps it can be salvaged after a bath in injector cleaner. Before driving, I gave the Camaro a much needed wash with Meguiar's gold wash.

I roughly followed the GM driving cycle instructions to remove the permanent code: http://www.obdii.com/drivecycle.html

I drove the car 50 miles, allowed it to cool down for several hours and then drove it an additional 50 miles, mostly on cruze control. By the time I arrived home, the CEL had turned off. I checked with the OBD scanner and saw both "permanent" and "pending" codes had cleared themselves. The "stored" codes do remain and did not erase when instructed to. Should I be concerned about this? Gas milage appears to have improved. I do believe my issue has been resolved and hope my experience can help those with a similar matter. I will update if the CEL reappears.

Now bank 2 exhaust is throwing an over-advanced code. I am replacing the solenoid today. Car is about to hit 90,000 miles.

Unhappy same issue

I have the same issue. Mechanic said that timing chain replacement needed, so i did it, but after 2000 miles code came back.
The car running normally, but when I drive aggressively for a long period of time on a highway car losing power dramatically and the engine light comes on. After 30 minutes of idle, it runs normally like nothing happened

I would like to read you post before i spend a lot of money and time replacing a chain instead of trying change solenoid first (

Wintertopdown, did any issues with Bank A or B solenoids persist after you replaced both?

Not sure if this helps or anything, but i had the EXACT same problem. i just went ahead and replaced all 4, and just last night from a spirited driving road trip, the CEL came back on with the same code i had when i replaced them 5/6 months ago (about 10k/12k miles ago). i kept my old parts, gonna clean them and just process of elimination at this point, and if that don't work then i'm just going to warrenty my vehicle.
