Hello All,'
So I got into LR2 couple days ago. Ran terrible/flat and got a check engine light. Rough idle and ect. Did some searching and decide to take the drivers side VVT Solenoid and the VVT to clean inspect. I didn't remove the passenger side because it's under the engine mount. Have codes P0016 and P0018
1. The VVT (short one in center) solenoid clicked when voltage was applied but only moved about 1/16 inch and had to push it back to rest to get it to click again.
2 The longer one next to the cam sensor had perfectly clean micro screen, clicked when voltage was applied but when shook end for end it rattled like there was spool loose inside or something. (Normal?)

Anyone have any experience with these?

 

I need to check the shop manual to be sure but I believe that the intake cam and the exhaust cam both have sensors for checking their position.

And only the intake camshaft can alter its position as well as it valve lift.



With this in mind only the Variable Vale Timing Solenoid (the long one) will have an affect on the codes P0016 and P0018.

The Variable Valve lift will affect drivability and power of the engine but not the position of the Camshaft relative to the Crankshaft.

P0016 OBD-II code mean? When a P0016 OBD-II generic code is triggered, it alerts the driver that the camshaft position sensor (CMP) for bank 1, which detects camshaft rotation, is not corresponding to the crankshaft position sensor (CKP) signal


I believe that P0016 is for one of the Cams and P0018 is for the other Cam so if the ECU believes that both are problematic then it is more likely that the refrence point is problematic.

Crankshaft position sensor

How clean is your Brake booster Vacuum Pump?



The crank sensor is under the pump and likely contaminated by dripping oil



Good luck

PS I own two 3.2s and both are around 150K and I have never had these codes but my 2008 LR2 has used Mobil 1 0W40 since new and my 2010 S80 3.2 Booster was repaired by me when I bought the car for my son to drive. The picture above is prior to me fixing the S80. Here is a picture of my LR2 in the area under the pump (this hasn't been cleaned)

 

The vacuum booster pump is dry/not leaking.
So I found this...P0016-00 Crankshaft position -
Camshaft position
correlation - Bank 1
sensor A - No sub type
information
Then for P0018-00 Crankshaft position -
Camshaft position
correlation - Bank 2
sensor A - No sub type
information.Check the engine oil quality/condition. Check
the camshaft timing and chain. Rectify as
necessary. Check the VVT solenoid and
circuits. Refer to the electrical guides Install
a new VVT unit as required.

Post a picture of the Vacuum pump and the timing chain cover that it is attached to.

You seem to be lost in this diagnosis.

1. The 3.2 has two camshafts and only two (and there aren't two banks like your code description would have us believe)

2. The Bank 1, Bank 2 is misleading (its and inline six not a V-6) but Land Rover Volvo assigned some codes as if it is a V-6

3. Only the Intake Camshaft has variable valve timing (so if the Solenoid has failed then you should get P0016 or P0018 not both)

4. The Exhaust isn't variable
Check the camshaft timing and chain. Rectify as necessary. ----- Good Luck with that, Let us know what you find out. (it is possible that the timing chain guide broke, do you have over 300,000 miles on the engine, these aren't known to fail)
Check the VVT solenoid and circuits. ------ Meaningless for the Exhaust Cam
Refer to the electrical guides ------ Meaningless for the Exhaust Cam
Install a new VVT unit as required. ------ Meaningless for the Exhaust Cam

5. If you are looking for a sensor that would affect Crankshaft time with respect to the intake and exhaust Camshafts then that sensor would be the crankshaft sensor (and you can check its wiring etc. that makes sense)

6. It is possible that Camshaft position sensor failed and the Variable valve timing Solenoid failed. (the Engine will only set the MIL if it can't maintain emissions and one sensor failing likely won't do that)
You can get a new sensor and see if it fixes the problem. It should be LR014372.

Have fun

I am connected currently... Here is a screen shot. I also found this in the manual. NOTE: For diagnostic purposes the cylinders are divided into two banks: Bank 1 - Cylinder numbers 1, 2 and 3. Bank 2 -
Cylinders 4, 5 and 6. It appears that the Cam Profile Solenoids are split, hence the pass/drivers side. I reseated the connector for Bank 2. I believe that is where the P001D-00 code came in. Ill run back outside and rescan in a few mins.

 

That clears up how they defined Bank 1 and Bank 2

Bank 1 = exhaust

Bank 2 = intake

The 001D and 0018 indicate that the Variable Valve Timing Solenoid may have failed (but it shouldn't set the 0016)

It is possible that the Camshaft sensor failed first and you are only noticing it now that emissions cannot be met.

Swap the camshaft sensors and see if that helps and check all of the wiring.

Good luck

Sometimes

For Variable Valve Lift just to make things confused the variable valve lift

Bank one is 1, 2, 4
Bank two is 3, 5, 6

Which is almost what you wrote

That kind of makes sense because there is one actuator for 1,2,4 and another for 3,5,6

For the position sensor there is only one sensor per camshaft and they shouldn't have two codes for the same sensor

So I am going to assume that 0016 and 0018 are different problems.


You can replace both sensors (cam position) and the timing solenoid for about $200 if you get aftermarket parts

Swap the Cam sensors and if one of the codes disappears then you only need the solenoid and one sensor.

Good luck

So what I am thinking (could be totally wrong) is that sensor "A" is seeing that both banks 1 and 2 (on the intake cam) are not the seeing/reporting the correct position/timing in relation to the crank? If the VVT solenoid is not functioning correctly it makes sense that both of the cam profile solenoids would be unable to adjust correctly and that trips both bank 1 and 2 at the same time? Looking at oil passage flow and it appears the VVT solenoid bleeds off pressure. So if the VVT solenoid is stuck open/closed the cam profile solenoids are getting unexpected pressure so wouldn't be able to function properly? Your inputs are greatly appreciated of course and thank you in advance.
