Engine codes p0016, p0341 and P1314

Hi, Naser.

Hey, I need a production date and if it falls under the CPKA or CPRA engine code. There's a sticker just below the cam phaser that has a bar-code on it. The engine code is by the bar-code.

The two codes you have that I feel are the cause of the issue relate to the cam and crank sensors. Something is not timed correctly.

Let me know.
Joe

I see, so around the timing cover? is that where the phaser is on these cars? you mean without removing any parts or covers there is a sticker?

It should be near the timing cover. If you can't find it, there should be a number stamped on the top of the engine block where it attaches to the trans. It really only deals with emissions designs, but I want to get the right info. If you are in CA or in a state that requires CA emissions, then chances are it is a CPRA.

Has been a Florida car all its life time, am in Alabama. I will check and see what i can find.

Here.

It says there was an answer to the question, but i don't see one.

Let me try this again.

General Description

The camshaft's task is to operate the valves at the right time and in the right order to control the charge cycle. Camshaft adjustment using the Camshaft Adjustment Valve 1 (N205) varies the opening times of the valves to suit all operating conditions. This ensures ideal charge cycles within a wide range of engine speeds and loads. Fuel consumption and pollutant emissions are reduced, torque and smoothness increased. In engines with a double overhead camshaft the size and positioning of the valve opening overlap can be influenced, enhancing characteristics in full-load and part-load operation. In continuous camshaft adjustment, the adjustment is infinitely variable within specific parameters.

General Description

Using the signal from the Camshaft Position Sensor (G40) , the precise position of the camshaft relative to the crankshaft is determined very quickly when the engine is started. Used in combination with the signal from the Engine Speed Sensor (G28) , the signal from the Camshaft Position Sensor (G40) allows the Engine Control Module (J623) to detect which cylinder is at TDC. The fuel can be injected into the corresponding cylinder and ignited.

Let me know if you get these.

in the first part where you describe the camshaft adjustment valve N205 , and camshaft position sensor in the second part, where are those located? In the first part for the N205, are they asking to test the resistance on the harness ins or the sensor's pins?

Naser, that is for the harness, pins 1 and 2.

Remove the engine cover to access the adjustment valve (N205). The attached directions and pic refer to removal.

- Remove the bolts - arrows - and then the Camshaft Adjustment Valve 1 (N205)


Let me know.

Joe

so am I looking at two things here? camshaft sensor under the cover and what else?

Am not getting any resistance between the connector pins. And am not getting any voltage between either of the pins and ground.

Deleted code and started hard to start first time and now i have p0341 alone.

Found camshaft position sensor, voltage at terminals 1 and 3 is 5 v with ignition on.

The voltage is spot on. I attached 4 pictures below. They are the diagnostics specific to this issue. Take a look through them and let me know if you have questions.

The pictures are in order of testing.

Joe

Harness connector terminal they mean the connector pin?
Where is the engine control module located? And when they say remove it meaning just unplug it?
Am guessing we looking for continuity issues?
Are the engine control module connectors usually labeled?
What about the fact that there is nothing i can get out of the camshaft adjustment valve?
Sorry trying to get my head around it. Am hoping it's not a chain/timing issue.

As far as labels, I attached info and a pic (pic 1) related to pin locations. Yes, you need to confirm continuity.

Unplug the module, but make make sure the battery is disconnected before you disconnect or connect the ECM.



Under the hood. Remove the E-box cover inside the engine compartment (see pic 2) to access the ECM. See pic 3

Please let me know what you mean by you can't get anything from the camshaft adjustment valve..

Joe

For p016 you sent me some instructions on checking the camshaft adjustment valve, so i followed it and found no resistance between the two pins in the harness connector. Also not getting voltage between either of the pins and ground. The sheet is attached.

Are you checking the component or the harness for resistance? The resistance should be when checking the component. If there is no resistance, then it's bad. When you check the harness side, that is where power should be. If there is none, then you need to start tracing wiring to see where the open is. However, before going crazy, make sure there is continuity to ground via the harness. If there is no ground, it will show no power.


I hope that makes sense.

Joe

I think I misunderstood you when I asked previously, I checked resistance between the pins on the harness, I think I tried to check resistance between pins on the sensor unit and no reading was found. So check if there is continuity between the harness pins and ground? what should it show on the multi-meter?

Naser,

I'm getting confused now. LOL between this one and the other vehicle you're working on, I'm getting lost. You should be confirming power to the harness by attaching to a known ground. How many vehicles do you work on at a time? LOL I give you a lot of credit. I would lose my mind. LOL

Ya, am sorry all German cars have similar issues. To check continuity to ground on the harness side of the camshaft valve which is on the timing chain cover, i would check it via multi-meter to see if there is continuity between one of the pins and any ground, what will the multi-meter show if there is continuity? Ya, i have lots of cars and I always try to challenge my self to fix them and better understand wiring and testing. Appreciate your help.

Okay, let me start one at a time. when checking the camshaft valve adjustment solenoid on the timing chain cover, resistance between the pins if the solenoid itself is 6.7 ohms. With the harness disconnected checking it with a test light there is power in one of the wires with ignition on. If i use the multi-meter and check voltage across the 2 pins of the harness i get 9.75v. Battery voltage is 12v. If i use the multi-meter and touch one aide to the negative battery terminal and the other to one of the pins i get 2.19v if i touch the other pin i get battery voltage.

Also when i touch one if the probes if the multi-meter to the negative battery terminal and the other to one of the pins to check continuity i get value of 1550.

Now for the camshaft sensor on the bottom of the cylinder head. checked continuity and resistance between it and the camshaft sensor and all were good around .3 or .4.

Okay, so i removed the valve adjuster and it looks good. i believe someone has removed it and the sensor either to look , clean it, or replaced it. Also forgot to mention that the first time uou start it when cold it will make this chain noise attached.

Good Lord!! Is there oil in it? LOL Is that noise from the top end?

Yes, there is oil.

Reminds me of the phasers on Benz when they went bad, but they still drove excellent.

Yes, the cam codes and the noise is telling us the camshaft phaser is worn out or the oil pump pick up screen is plugged. can you look inside the valve cover to check for oil sludge build up please? If so remove the oil pan to clean the screen. Can you please shoot a quick video with your phone so we can see what's going on? that would be great. You can upload it here with your response.

But sludge would cause it not to have any power? Maybe due to sludge in the valve cover and the sensors not able to read?

Yes, if there is no oil pressure getting to the phaser the camshaft is fully retarded. Or the timing chain/belt could have jumped a tooth causing the noise and low power.

So I removed the rubber cover on lower timing chain cover and the tensioner is about reaching its limit. So I put it inside my garage and I would need to do a chain job on it before it's too late, I guess the chain has stretched. I know it needs special tools but I always invest in tools. Doing a job like this and since timing is off, would you start by removing the chain where it is now and then time everything then put in the new chain? or would you put it in time first then move on? My thing is how will I put a car in time if the chain has already stretched? it would not sign up.

I though it could be the chain. here are instruction int he diagrams below to show you how to do the job. Check out the diagrams (below). Please let us know what happens.

I appreciate it a lot. But how you address it? If it's stretched and cannot be aligned. how would i go about beginning? I ordered the kit for all these tools. Or it doesn't matter right now since its out of timing.

Order the new timing kit then realign the marks you should be all set.

what am asking is, I cannot align it first before removing the chain, because the chain is stretched. So would you leave it like it is, remove the chain, realign and install?
