Question about Jaguar 1998 XJ8 Base

Open Question

VVT code P1396

Engine code P1396, VVT, after changing timing chains and tensioners on a 98 Jaguar XJ8 base model. Variable Valve Timing code has become problematic. I've tested all the connectors and the solenoids, triple checked the timing and torn everything back down to chain replacement a second time with the same result. There was no code before the chains were done. I've followed advice from other forums and done everything they said to check and I can't work out the VVT issue.

P0022 for 2004 toyota sienna van


P0022 Toyota - Camshaft Position \'A\' Timing Over-Retarded Bank 2



























Possible causes




- Dirty Oil

- Faulty variable valve timing (VVT)

- Faulty oil control valve (OCV)

- Variable Valve Timing (VVT) harness is open or shorted

- Oil Control Valve (OCV) circuit is open or shorted

- Damaged Engine Control Module (ECM)




Tech notes



If the engine oil is clean and the VVT and OCV circuits are OK, replaced the VVT to resolve the problem.





When is the code detected?


After the ECM sends the target duty cycle signal to the OCV, the ECM monitors the OCV current to establish an actual duty cycle. The ECM determines the existence of a malfunction and sets the DTC when the actual duty cycle ratio varies from the target duty cycle ratio.


Possible symptoms


- Engine Light ON (or Service Engine Soon Warning Light)

- Lack/Loss of power

- Engine rough idle


P0022 Toyota Description


The Engine Control Module (ECM) controls the Oil Control Valve (OCV) to regulate the intake camshaft angle. As a result of the angle change, the engine timing is advance or retard. Optimizing engine timing will help the engine improve torque and fuel economy, and the exhaust emissions decrease under overall driving conditions. The Variable Valve Timing (VVT) system includes the Oil Control Valve (OCV) and VVT controller. The ECM detects the actual intake valve timing using signals from the camshaft and crankshaft position sensors, and performs feedback control.

What is code 1388 on a jaguar 2001 and how to fixit


this indicates a problem with the variable camshaft timing and possibly requires reprogramming PCM module
assume the engine warning light is on? does the engine run normal?

The timing gear tensioner on my stype jaguar 2001 was replaced after the chain guides broke...a common failure for that year with plastic tensioners...would it not be a normal procedure to check or replace...


Failure to change your oil every 4,000 at most,
takes out VVT Actuators

When you do the guides you do the tensioners
Again no oil flow & gunked up

You can see the VVT on scan tool parameters & also
should mess with fuel trim data

If you change the upstream O2 Sensors at 100,000,
spark plugs every 3 years & clean the MAF you at least
have a clean start, with the exception of the cam & chain issues

Error code p1384 and 1396


Hi there:DTC P1386 - VARIABLE CAM TIMING OVERADVANCED

Possible Causes:
- Bank 2 VVT solenoid valve to PCM PWM drive circuit fault.
- Bank 2 VVT actuator oil supply fault.
- Bank 2 VVT actuator stuck.

The biggest issues with vvts are oil supply issues. Useally debris like oil sludge in oil pickup screen, loose bearing clearances as an engine wears, and oil passages blocked/partially blocked to and in vvts. The first (i always shoot for cheapest potential likely fix) use a good engine flush(2 bottle for our higher than normal capacity engines) follow directions on bottle. Change oil and switch to a 20-50w. Leave out 1 quart and add 1 qt auto ****** atf(highly detergent, more so than engine oil and wont hurt anything) while you have overly ******** cam codes, it may be an issue of apply and blockage that keeps pressure in vvts too long when supposed to release. Most times its ******** cams( like the 1 i am doing right now....try this first and go from there, rememebr to clears codes and give time, you may have to clear codes a few times as it may continue to reset.



DTC P1396 - VVT Solenoid Malfunction - (B bank)

Check HERE a TSB about this faylkt code.




Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Noting the position of the primary timing chain guide, remove the primary timing chain guide from the upper retaining pin. See Fig. 149. <br />Remove the primary timing chain from the variable camshaft timing oil control unit and from the crankshaft sprocket. Clean and inspect all components. <br />Installation <br />If "B" bank timing chain was removed, see INSTALLATION. If not, go to next step. <br />If previously removed, install the timing chain sprocket to the crankshaft. The teeth of the "A" bank and the "B" bank timing chain sprockets on the crankshaft must be out of phase with each other. If they are in phase after installing, remove the sprocket, turn it on its vertical axis and reinstall sprocket. See Fig. 150. <br />Install the chain tensioning tool to the exhaust camshaft sprocket. Reposition the sprocket (and the variable camshaft timing oil control unit) for the most advantageous position for use of the tool. See Fig. 151. Remove the tool. <br />Install the primary timing chain into position over the crankshaft sprocket and the variable camshaft timing oil control unit. There must be no slack on the drive side of the primary timing chain and the sprockets must not be rotated on the camshafts, or the tensioning tool may not fit.

The Jaguar v8 does not have a rocker arm or push rods, this is an overhead cam type engine.
4 cams on top of the heads which are driven by the timing chains, which are driven off the crank.
If your noise appears from the lower end, the most common issue is a main bearing in which case the car will need an engine. (the bearings go bad due to lack of oil circulation, the oil pick up tube in the oil pan gets clogged)
If the noise is upper and the car seems to run rough then the upper timing chain tensioner has broken and the chain has jumped causing the timing to be off.
If you start the car and you have a bad upper noise then the chain could be broken and by running the car you definitely will have valve damage.
