Strange problem Focus 1.6TDCi

**BRAVO6** · 13th March, 2013, 01:51 PM

2008 Ford Focus 1.6Tdci PSA engine. Car occasionally gives momentary hiccup. Allways only for 1/4 or 1/2 second stutter. Can happen hot or cold cruising or accelerating. Seems totally random. Happened 2 or 3 times on first test drive. Drove car for 10 miles only happened once. Originally 4 faults stored but none of these have returned.
Original faults
U0073 Can Communication Bus Fault
P193B Throttle/Pedal fault
P1936 Clutch switch/sensor signal
U0416 Invalid data received from VDM

Don't know if these have any relation to the problem, because no faults now. Where do you start.
Just thought I'd put it up in case anyone has come across similar.

It's the clocks causing the problem, bad connection.

When your Instrument loses connections the CAN System Malfunctions and it triggers the Engine Management Light as there is NO instrument malfunction light...........

It also records fault codes in Engine ECU.........Also don't forget the instrument is part of immobilizer system on this vehicle......

Even if you look in BCM you will see some fault codes for instrument malfunction.........

No faults in BCM, ABS or instrument. Only faults were those mentioned above in engine and they didn't reappear even though problem was still there.

change fuel filter.....add good diesel injector cleaner.....clean egr valve...........try all these before messing at dashboard.

have had loads o these inc c max etc with faulty clusters but usually throw up loadsa communication fault codes when these are at fault..and will even stop dead on the road and fail to restart.......goodluck

My friend if you agree the instrument is faulty and causing this kind of fault which will also cause some times not to start.............

Then WHY you want him to spend his money to change the fuel filter and clean EGR system.............???????????????????

because he has stated that the fault still persists,,,,,

but there are now no fault codes,,,,,,,,,,,,,,,,,,,,,,,,,,,

cluster problem , there would be constant communication faults returning......................................... ................

Start from + and ground
or wiring loom under battery

**pandokrator** · 21st March, 2013, 12:16 PM

just follow the wires from pedal potentiometer to the dash.
is 3 wires.
pedal send signal to dash,then from can bus dash send signal to ecu.
cut off old wires and add new.
this works for me in many focus.
here the diagram.
