XC70 00MY P0014 Cam Position Code

Postby ldiii@hotmail.com » 09 Mar 2009, 21:07

I’ve got a P0014 “Cam Position Activator B, Bank 1, Timing Over Advance" code that I can’t get rid of. I’ve replaced the Cam Actuator Solenoid so that shouldn’t be the issue and I’m sure the timing is perfect. I’m thinking that it might be the Cam Position Sensor, but before I go that route I wanted to post here to see if anyone could tell me how to test. I don’t want to buy a new one if I don’t have to!

If anyone has any info on this I'd greatly appreciate it.

That code points to a problem with the continuously variable valve timing control solenoid. None of my cars have CVVT so I have no hands on experience with it. Hopefully others that have worked with it will jump in.

I did a bit of research on this over on VolvoSpeed:
http://www.google.com/search?sourceid=M ... com+=P0014
And my conclusion is that even though your car might be running fine, it could be a tooth off or it could actually have an oil pressure problem to the solenoid itself. What you describe is hardly ever the Cam Position Sensor itself.

So, did it perhaps start setting the code shortly after a timing belt change?
It's not uncommon for the timing to be off. Trust me :wink:

If you are positive the timing is correct , then I have a VVT solenoid, that there is nothing wrong with, that I would give you a fantastic deal on.

thanks for the quick replies guys. is the VVT solenoid the same as the cam actuator solenoid (this has already been replaced)?

It sounds tho like it is not the cam position sensor.

in response to your question larryh, I don't know. I got the car just after the timing belt was changed, so don't know if that code was being thrown before or not.

It is the same thing. Your code indicates that the timing is overadvanced, not that it isn't working.

Correct, the timing belt and condition of the timing gears needs to be checked, probably very soon, given that the t-belt was due at 105K. If the belt has stretched it could break soon and that would be fatal to the engine.

I've been in your shoes.

Bought my car at 114k, the car had just recently had the timing belt done at 105k. I replaced the VVT solenoid due to the P0014 code, it kept coming back. I then followed this fellow's advice and changed the camshaft position sensor:

Since the VVT relies on oil pressure, oil quality and oil pressure are crucial. now that i am keeping a close eye on the oil level, i have not had the code in 9 weeks and counting.

thanks for the post db130. so you did end up changing the cam sensor? what did it run you if you don't mind me asking? I think I'm going to check the timing one more time to make sure that isn't the prob before pulling the trigger on the sensor.

my fuel economy is suffering due to this as well I believe. I'm only getting 20 mpg on the highway when I believe I should be getting much higher.

Postby db130 » 12 Mar 2009, 18:49

yes, i ended up changing the camshaft position sensor which at the time cost me about $150. i see that the price has gone up to around $200 from online wholesalers(dealer retail is ~$246)..

i have to tell you though that the code came back 8 days after i installed the camshaft position sensor, although the camshaft position sensor did fix the intermittent hard start problem. i changed the oil shortly thereafter and and have been keeping tabs on the oil level. Before the new camshaft position sensor, I'd get the P0014 every two weeks or so. After the new camshaft position sensor+oil change, the interval started to grow longer. I last had the P0014 back on 01/05/2009.

By the way, when was the last time you had the oil changed?

I still think you (both now) have the timing off. Shops can, and do get the timing off when they change the belts on the vvt cars. it is tricky to keep things positioned and the crank mark is invisible. as was the case in my car (only it was me that did it the crappy work as soon as I purchased the car) the car ran fine..mine was a tiny bit sluggish but i didn't even notice that until it was corrected. The code can be very intermittant.
Good luck

db130 - I changed the oil about 4k miles ago. I use Mobil1 and she burns very little oil. The oil still looks good too. I'm going to change it soon, but even after I've changed it in the past the light comes on so it doesn't seem to make a difference.

larryh - do you have any tips on how to best check the timing?

thanks in advance.

Just a quick update... It is now 14 weeks and counting since I last saw the P0014 code. Proper oil pressure/quality+new camshaft position sensor apparently was the cure.

I going to have to dispute the assertion that the timing belt is off by one tooth on my car. I have an aftermarket vacuum/boost gauge on the a-pillar and the vacuum/boost readings during idle/acceleration/deceleration are all spot-on for "factory spec."
