This car will start with difficulty, sometimes 10 - 12 cranking attempts, then it will idle fine but will cough and splutter when revved.
In the short time I had, I could not identify the correct engine code but can confirm the control unit is a Delphi DCM 3.5
Each time it will throw a P0335 CKP Code. If I disconnect the CKP the engine will die instantly, no surprise there!
I got this capture back probed at ECU
This has a Magnetic Phase Ring, not "teeth" on the Crank. A 3 Pin Hall Effect Crank Position Sensor.
I have heard all about the history of this fault, I don't believe any of it so wont bore you with that.
What I do know, looking at invoices from Ford Dealer is that it has had a Cambelt, Timing Chain in the Head, a Magnetic Crank Phase Wheel. Then Advised that it needed a new ECU and Software Update .....
The Extra Missing "teeth / tooth" looks Wrong to me ? If this was a weekday I would have ordered another and fitted it but being the weekend I am unlikely to get one until Tuesday
Normally I would not have to ask this question, but it has already been fitted with a New Genuine Ford CKP Magnetic Wheel at the Dealer. That has made me Question & Doubt myself.
I believe the Magnetic Wheel is faulty, I don't see a Correlation / Synchronisation Issue ? Can anyone confirm whether my Diagnosis is good or bad ??
I assume that you changed the ring and fixed the fault?
Just thought about another option. One magnet on ring could have weaker field and when gap is too big then that weaker magnet would not trigger the sensor.
