As I am sure you are aware the VQ has two camshaft Position sensors, one for each bank. Each sensor is secured to the head by a single bolt. When installing the new sensor the torque spec for the bolt is 85 inch-pounds (not ft-lbs).
When I went to autozone and had them pull the codes the first one that came up was p0340 on bank 1.
And after researching the symptoms other have seen with a bad CPS I am having the same exact issues (intermittent hard starting, loss of power)
The other code was p051, which I believe is the O2 sensor.
I suspect that once I take care of the cam positioning sensor the O2 fault will resolve itself...
So it sounds pretty easy to replace the CPS. Just take old one out and put new one in
Can you tell me which is bank one of the motor.
Warhammer if you would post some images from the service manual that would be great...
On a side note, as I was researching the CPS, more than one person stated that they had the p0340 fault code come up after they changed the battery, same as me...
Seems like a very strange coincidence??
Also be sure not to leave the battery disconnected for too long. Disconnecting the battery for too long will force you to have to perform some relearns. Here's a pic of where the cam postion sensors are:
After 142K miles, my MO is history. Now sporting a loaded silver 2012 Ford Edge Limited with 20" wheels.
To finish Njjoe's note...why do you also think the O2 sensors are bad? Those guys last a very long time.
I have a Service Manual & I can post pics if you need.
I know this is extremely old thread but this is only post on web where someone offered to send pics of where these two suckers are. Code says one bad but thought I might as well replace both as I have 150000 miles on car. If you still have pics could you please send? Do you think I should replace oxygen sensors while I am at it? Thank you.
he did post a pic. look at post 7. click on the little pic to make it bigger.
My wifes car got code P0345 today. a few weeks ago it was losing power and getting it back. Lunging, but due to a power loss, not gain. No SES light came on or anything. Well she drove the car for the first time today since then and the SES, VDC off, and SLIP light all came on while driveing. when she got back in the car, only the SES light was on. Does this sound like a sensor or something else? Could the sensor be getting a signal saying the camshaft is off? bad timeing?
