Engine swap nightmare EB2FA

Hi guys hoping someone can help me.

Bought a 67 plate C3 with an engine problem. Basically the previous owner has hit the sump and the resultant lack of oil caused a failure and engine knocking.

I purchased a used engine with only 1k miles on from ebay and the engine match was ok apparently. \however the new engine has the management light on with codes P0014 and P000A, basically the camshaft A and Camshaft B timing is all over the place. On further investigation the replacement engine is code EB2FA - I can only see EB2 on the origional. Im thinking the ECU is not 'talking' to the engine correctly! Can anyone please advise me if this is programmable or do I need another engine swap?

why me!

Hi

EB2FA is not listed for Citroen models. Did it come from a C3 donor?

The EB2FA is listed as 55kw whereas the EB2F designation in the C3 is listed as 61kw so there are some differences in the engine design or ECU programming. I don't know which.

Seeing as EB2FA was not fitted to a C3 (as far as I can see) I don't think there would be any programming known for that to copy across to the C3 ECU.

Always best to pick the engine and other parts from the same make and model donor. Although many parts are similar across the PSA range, you can always find something to catch yourself out.

You may just have a genuine fault?

Oh now I am perplexed I bought the engine off ebay from a legitimate salvage company which showed photos of the car itself.

Ill attach the ad.

cheers

Just found another one on EBAY so I assume Citroen did use them. can anyone confirm?

I don’t know a lot about these new-fangled engines, so take what I say with a grain of salt.

Is the engine running? Have you driven the car yet? How does the engine run? Smooth? Lumpy? Not running? Any other faults/codes/strange things happening? Any info will help.

I wouldn’t throw the baby out with the bath water just yet.

Looking at the OBD codes it looks like the cam timing is both too advanced and too retarded. My guess would be that the Variable Valve Timing (VVT) is not working (correctly).
Classic failures here are the oil (wrong grade of oil/dirty/old) and the electro valve that controls the hydraulic pressure. These are by no means the ONLY possible failures, but they are the most common.

As C3CAR says, the engine may have had this fault in the ‘other‘ car. You just don’t know.

If the engine runs and propels the car along, you are 99.9% there.

Hi thanks for the reply, the engine starts up and moves fine it is just way underpowered uses way too much fuel. Hates setting off in first gear and generally drives poor.

I will change oil and filters and look at the vvt this week and let you know. I'm considering buying an ECU specifically that matches up this engine but I'll leave that for now

Once again I'm not too familiar with the current batch of C3's.
However if PSA are up to their old tricks, the engine ECU will have a PIN code.
You will need to know the PIN code for the replacement ECU AND the PIN code for the current ECU!
You will then need to code your keys into the replacement ECU.

If there are no other fault codes I would postulate that the engine ECU is 'working'. The ECU is finding all the sensors and actuators it is looking for and all but one is doing what the ECU expects them to do. I do not know if the valve timing would degrade the engine performance as much as you say (I am not that familiar with the VVT system) but I guess it's possible.
It is possible the fuel trims are wrong and the injector types are wrong, causing fuel consumption issues. Check the spark plugs and make sure all have the same amount/type of deposits on them. They may be sooty from over fueling but they should all be the same.
You could do a bit of research on the injector types for the two engines. Generally speaking, if you have 2 engines that are basically identical but one produces more power, the manufacturers just extend the rev range for that engine. This means the engine ECU will let you rev the t!t$ off the engine to get the extra horse power...not a good idea IMHO.
