Ford S-Max 2.0 tdci - P003A:17-2F - correct VANE POS values

Post by mkaminski100 » Mon Feb 13, 2017 8:39 am

Patient - 2007 2.0 tdci (DW10) Ford S-Max
Suffers from P003A:17-2F code

===PCM DTC P003A:17-2F===
Code: P003A - Turbocharger/Supercharger Boost Control A Position Exceeded Learning Limit
Additional Fault Symptom:
- Circuit Voltage Above Threshold
Status:
- DTC Present at Time of Request
- Malfunction Indicator Lamp is Off for this DTC
Module: Powertrain Control Module



Error is recorded during start up.
Vacuum valves replaced with working units.
No vacuum leaks.
Vanes move by around 1cm when vacuum is applied - to be checked against values on the oscilloscope.
Vacuum level not checked yet.
Vane position sensor replaced. Resolved problem for some time.
Correct diagnosis is difficult due to lack of correct values, so could I please ask to provide an oscilloscope view from VANE POS during start up? I will try to take a snapshop of those values today to compare
It would also be highly appreciated if someone could provide correct voltage applied to the turbo vane sensor. I'm sure one should be 5V reference, but not sure about others.
.


I suspect:
- worn out vacuum pump - rather unlikely
- vanes not moving in full range
- wiring harness to the vane position sensor or ECU

Thank you in advance.

Not too sure what your saying in your post, but it's most likely the Position Sensor.

If you have replaced that, then have you cleared the previously learnt values in the PCM?

Yes, it's regarding VANE POSITION SENSOR (boost sensor) on the turbo charger. My question was regarding correct values of "VANE POS" in ForScan during start up to compare with my results. I have so far only read those during tick over (attached snapshot).
I have reset the PCM learned values several times during this process (I had other problems with this car), but I'm not 100% this was done recently or after removal of the sensor. I will reset again today.
I could not find any specific feature to clear VANE POSITION sensor and I should reset the whole module. Is that correct?

Yeah, reset the whole PCM. I would also be tempted to re-boot the module before running the Reset All Learned Values setting.

EDIT, actually what I would do is this...

1.) Reset/reboot the module
2.) Clear error codes
3.) Reset All Learned Values

Sorry for dumb question, but is there a "reboot" function for the PCM? I think I could only find reset of learned values, but I might be wrong.
Thanks for your help

Yeah, there is a whole host of modules that can be rebooted/reset/reinitialised. I don't have my laptop here, but I'm sure it's in the Vehicle tests section, or Service procedures. I'm sure is says PCM Module Reset or similar.

The last part of the dtc 2F indicates an erratic signal was received which could be caused by a faulty connector or wire damage.

I found both "reset" and "reboot" options and after performing both the error no longer appears.
This does not mean it's gone and I suspect that William might be correct. This error (P003A) appeared after clearing of P2566 which I managed to remove after removal of the plug on the turbo charger. Code P003A:16-25 appeared after little play with the turbo. It changed to P003A:17-27 after replacement of the vane sensor. Any idea what 16-25 means?
One of cables was kinked, but didn't appear broken or damaged. I can't verify this as the ECU is secured with a shear bolt which I have not yet removed.
I can't drive this car yet, so it's just testing in my garage, which takes longer for codes to come up.

No further improvement.
What I have noticed:
- all cables between the sensor and the PCM are fine
- VANE POS when the engine is not running is 0.6V
- when I apply vacuum to the sensor, values go up to +150V, then drop to -150V i go up slightly.
- sensor changes values only when the actuator moves more than 3mm. It does not notice anything within the first 3mm.
Snapshots of readings attached. Do you see anything unusual?
I can't see anything out of ordinary.

Hi,
did you solved that issue?
I've the same problem on my car, a mondeo 2.0 TDCI 140 CV late 2007. Engine code is QXBA.
I've just replaced the vane position sensor but the DTC is still present.
