Ford Mondeo 2.0 TDCi 2002 - Code P2337 Cylinder 2 knock threshold above limits #

Posted by Jeff Perrin on May 2, 2012, 2:47 pm

Year of Manufacture *: 1952
Engine Size and Code *: 2.0
( Optional ) Scanner Used: Delphi DS150

We have a mondeo that is poor starting and when it eventually coughs into life it runs like a sack of spanners. A code read brought up P2337 'cyl 2 knock threshold above limits'. To eliminate mechanical issues we removed front cover and checked valve timing and rocker cover to check valve gear and also checked compressions all ok. We have now fitted 4 new delphi injectors and coded them with the delphi equipment. As this fault code erases when the injectors are recoded we have checked that there are no fault codes present and that the injector count is at 0. Then if you turn the ignition off and then turn it back on the fault code reappears without even cranking the engine. My question is, How can this fault code reappear when the engine has not turned as the code represents an issue with how that cylinder is running?
Just to check that we have not got a faulty new injector we have swapped them round and recoded them and still the code is CYL 2 knock threshold. If the issue is there when the engine is not turning it cannot be a mechanical fault and we have eliminated an injector fault, also if it was a wiring issue surely the code that would come up would be a 'short to ground' or 'short to live' or 'open circuit'. As the fault appears before cranking it cannot be an issue with fuel pressure.
I have read the other posts on here relating to the fords and none the wiser.
Can anybody help as my fingers have now got splinters from headscratching.

Have you tested the knock sensor?

Think its by the pump on this engine?

Try putting p2337 in search box at top of page.

Re-enter the C2i codes using IDS and your problems will go away.

Hi Jeff

Theres a very long thread on here started by Dave Jackson back in 2007 on coding injectors on a 2002 Mondeo using CDP pro which I think is similar to your Delphi tool.
Just put Ford injectors on the search box and it should show up.

AHHHHHH!!!!!!!

What has this repair cost thus far Jeff?

Part of the problem maybe here....

Is that you or the car?

Roy
injector coding sequence could be your issue as others have said.
ie: is it coded in firing order sequence 1342 or cylinder position 1234 you need to check with the manuf. of your diag gear 'coz they often differ between machines.
my superscan does it different to my solus for instance

We have done a number of these using Autodiagnos. A lad I know from the dealership gave me this tip when having problems after fitting new injectors, before coding, road test the vehicle for a couple of miles then the tool allows us to code the new injectors without problems. Then road test again after coding is required for the new settings to settle in and get rid of the diesel knock. HTH

thanks for the input lads. I have read and reread all the posts on here and a couple of other sites aswell - mainly cos I can read quicker than I can type LOL. We have tried a knock sensor. We have coded the injectors using the original delphi and tried it in injector sequence and cylinder sequence, we have also tried coding with the X431 which definately uses the injector sequence. Currently the car is going to someone with ids to reflash the software (suggested by delphi) and obviously we will get them to see if the injectors will code properly.
Thanks

>>> We have coded the injectors using the original delphi <<<

With all due respect, the Delphi DS series tool is light years away from the original OE tool (IDS or WDS in those days)

just because its a delphi system it does not mean that it even has delphi software inside it!!
The PCM is made by Viston.

Run a calibration update and code the injectors with IDS (as you are doing now) and all will be good once more.
