Hello everyone
so after I rebuild my aj133 engine and get it back in the car, fire it up and the car has a rough runing
Check engine light is on reducing power message coming up
and 2 bad codes.
P001A-13 Intake (A) Cam Profile Control Circuit (Bank 1) - Circuit open (Refer to the electrical circuit diagrams and check camshaft profile switching solenoid bank 1 for open circuit)
P001D-13 Intake (A) Cam Profile Control Circuit (Bank 2) - Circuit open (Refer to the electrical circuit diagrams and check camshaft profile switching solenoid bank 2 for open circuit)

is it an electirc problom?
is it a macanical isue?
did i did somthing rwong in the timing?
can any on know where i suled start chacking?

Also, I have two connectors that I can't find any place that they need to fit in.
I can't remember if this connector was like that before I took the engine apart.
2 identical connector one on each side of the engine in the rear.
Coming a little bit out of the engine harness
I can't find any connectors in their surrounding.

 

So i did litle sherching on line and found somting very disturbing.
as i say before the engine thet is in my car is 508ps
whit no supercharg. (Propbobly few yers back the original 508pn engine had replace whit 508ps but thay take out the suprecharger.
in my engine i have no camshaft profile swiching solenoid.
thay are the 2 conector i cant find where thay go.



Im spichless ... all that 2 mounts work and all thet mony spand all for nothing.
what shuld i do now?
Can i buy this solenoid anf fit them?
There is a place for them to fit on the 508ps block?
Or i need to replace the harness and the ecu to asupercharg one?
but the car is n/a.
i cant bilive i didnt see thet before.
i fell so stupid right now.

 

Udiasi, where you live? Does your country have lot of Diesel vehicles? If yes, then there must be companys or persons who can rewrite ECM:s to disable EGR systems.
I would contact them and ask could they disable camshaft solenoids. However: There might be more difference on ECM than just solenoids...?

 

So as i sleepd on it.
i figure thet mayby thet is not the problom.
as the car has this 508ps engine for 4 years now.
and the car was runing fine.
so the open circut erorr cant be delited becouse the conector is disconected allways.
and in the s/c engine there is no hidrulic lifters in the heads so i dont need the solenoids.
i will chack today agine for eror codes and see if anything else comes up.
im afride thet i did something wrong wiht the vvt on the timing mayby.

 

Ok new ideas
i chack today data when the engone is runing.
cilynder 4 misfire.
cilynder 4 not working at all.

misfire in cylinder 4 rising fast.
i change the coil form 2 to 4.
fire it up and stil cylinder 4 not working.
I gat the plug out and its like new.
didnt work at all and no feiul smell at all.

and plug from other cylinder in look like its working.
so my best gess is thet the injector is not working.
Or somthibg whit the high preshure fieil pump timing is bad.
so what i shuld do next?
remove the injectors from 2 cylinders and replace them?
Mayby there is no spark?
Mayby the injector conector is bad?
what do you recomend i do next?

 

If I understand you correctly, you tested with plugs 2 and 4 reversed as well as the coils reversed and the issue with 4 misfiring persisted. That does suggest it is not the plug either. You can test the plug externally by just holding the stem against a ground and watching for the spark, but if the plugs worked reversed it probably isn't that.

You mention the injector connector - do you have a noid light you can test it with?

If you have one of those mechanics stethoscopes with the solid rod you should be able to touch on injector 4, even at the connector if access is tight, and hear the solenoid ticking. That won't tell you if it is blocked, but at least you'll know the electromechanical part is working.

If it sounds ok, I would avoid pulling both fuel rails to check the injectors are firing correctly because a) it is a lot of work, and b) the cross over tube is stainless steel not flexible and space is tight to do it all safely. As it is just the one cylinder misfiring it's going to be easier to just remove that single rail and swap over injectors for 2 and 4 to see if it follows. You could clean 4 when you remove it.

 

yes today i will swap injector 2 and 4 to see if the injector is bad.
but when i read about ristricted preformans i saw thet if the ecu fell misfire it will cut the feul to the bad cylinder to protect the catlitic convertor.
so maybe the injector wont work becouse of that feul cut?
dose it cut the feul only whan restricted preformans masage comes up?
or from the secand it detect misfire? becouse it detected misfire on startup.
and the plug thet i remove looks like new.
so if i swap the injectors from 4 to 2 and the misfire is change the cylinder 2 i will know thet the injector is bad.
but what if it will still misfire on cylinder 4?
what next?
compration chack on thet cylinder?

another question please.
what if i didnt get the lower timing right? ( the feul timing)
will it cose misfire on all cylinders?
not only 1?
becuse the car fell so wobbly whan i try to move it.
like somthing is off bad.
i had v8 in the past.
and never felt like thet whan only one cylinder is not working.
what am i mising?

 

So i swap injector 4 whit 6 today
and the misfire has moved to cylinder 6
so it seems the injector has failed.
i order 1 new today hope it will clear all the bad codes.
and the limp mode the car is in.
if it will... ill change all the injectors.
if not we will proced forword.
