Focus St Fault Help

4 posts in this topic

Hi I have a focus st 2006 with engine management light on and abs traction control light on, I have fault codes u2023-eo-abs coms fault,

P0076-e2-PCM intake valve control circuit low bank 1

P0079-e2- PCM exhaust valve control circuit low bank 1

P0102-e2 PCM maf sensor circuit low input

P0245-e2 PCM turbo/supercharger waste gate solenoid A low

P0458-e2 PCM EVAP system purge control vale circuit low

P0646-62 PCM air-con clutch relay control circuit low

B2477-60- EATC module config failure

B2609-30 HCM ecu output to left headlamp stepper motor circuit failure

B2612-30 HCM ecu output to right headlamp stepper motor circuit failure

B2619-70 HCM rear axle vehicle level sensor signal circuit failure

These codes where taken from the IDS diag machine and I am fairly clued up as I have a technician status level motor vehicle cert but this is beyond me :/ I think it's the PCM at fault :S any ideas of the fault would be much appreciated

Ouch, a lot there, so I would say that the issue does certainly seem to be PCM related, otherwise, I would be considering a wiring issue, perhaps a faulty harness... but as its cheaper to get a PCM from a scrappy, or sometimes even direct from Ford than a replacement harness, it might be worth thinking about!

Just a quick update I went through a pile of wiring diagrams and found one with intake, exhaust, maf and turbo sensors and began testing that circuit, eventually found a fault with the oil heat sensor thing in the oil filter housing.

Replaced the housing as a whole unit and the faults have cleared apart from headlight faults and instrument fault but I'm not bothered about that.
