Peugeot Boxer 2.2 110 NEW fault code P2137

[John1966]

Exiting day yesterday!!
The van threw up a NEW fault code (this is to add to the ongoing but probably unrelated DPF issues)

Fault Code P2137 throttle/pedal position sensor/switch 'B'/'C' voltage correlation

Symptoms
Van was intermittently losing power while running from cold, (has done before so didn't think anything of it as assumed connected to the dpf regen /overfuelling)
Then bang lost power hill assist warning came on and that was it.
Switched off and back on again with eml light on, not in limp mode and seemed to be running as ok (well as ok as it ever has done!)
Put on computer and cleared code, only for it to repeat the same scenario.

First thing would seem to be to replace the throttle position sensor, any idea where this is located?

If I hadn't invested so much into this van it would be going for a long drive on a short pier with a brick on the accelerator!

Once again HELP!!

Here you go. Basically htere are 2 tracks in the accelerator assembly that compare data with each other. This fault means that the data on the tracks is not comparable so as a safety feature some systems / actions are sisabled and as you can see this DOES affect particle filter regeneration!

Also your after sales campaigns is still outstanding for the door switch.

Fault Code:	P2137 62
Description of Fault:	Accelerator pedal sensor : not defined : Incoherence between the 2 tracks. Electrical fault in the signal from the accelerator pedal sensor. Time for appearance of the diagnosis less than one second Conditions of activation of the diagnostics At least one of the following conditions must be fulfilled: - With the engine running - Ignition on
Conditions for Fault to clear:	Driving for 5 min
Downgrade Modes whilst Fault is active:	Switching to fuel "reduced flow" mode with intentional downgrading of performance Irreversible deactivation of the vehicle cruise control Deactivation of regeneration of the after-sales particle emission filter, both static (vehicle stopped) and dynamic (vehicle on the move)
Symptoms:	Lack of power
Suspect Areas:	Electrical harness Connectors Foot throttle pedal

Many thanks for that info
On a positive note it says that it deactivates the regen........
Looks like I'm on the hunt for a new pedal, but will check out the wiring first.
I presume that the TPS is down behind the engine on this van, as that's where the air intake pipe leads to?

[GiveMeABreak]

No, it's all fly by wire now - the accelerator pedal contains the position sensors and transmits the data to the engine ECU that adjusts the fuel mixture accordingly.

Number on my pedal is 005332091900B7207163732215
Am I correct in cross referencing this to 16 139 981 80?

No that's not the part number John. If you want the official part number for vehicle VIN ending 440:

(1) Accelerator Pedal, part: 1607290480, £243.17

[John1966]

Thanks Marc
That part number info is interesting, as that number seems to cross reference with a different MPN (01369473080) on the pedal
Different from the one that was fitted
Looked to be the original that I removed, as the blue dob on the bolt was intact, but I suppose could have been incorrectly replaced previously?

[John1966]

Now pondering on this a bit further....
What would the consequences be if indeed this was the wrong pedal that had been fitted?
Van was running, accelerated, and until this failed apart from the dpf issues wasn't throwing any other fault codes.
Could this have been causing the dpf issues...... or am I barking up the wrong tree again (bearing in mind that I'm on the Outer Hebrides, and trees are few and far between)

[GiveMeABreak]

All I can tell you that the fault codes, when present, will result in the downgrade modes as described in the fault descriptor, and the part number I provided is the correct one for this vehicle, so yes it could of been previously replaced by an incorrect one. So it's perfectly normal for the incorrect part in this situation to cause some anomalies.

PSA will often use the same part numbers across a range of vehicles that share the same engine management system for example as it is cost effective to do so, and would not commission different parts unless there was a requirement to do so. So there is a reason why the part number is different which may affect the operation of the part and / or the data generated and sent.

Also PSA can use their internal part numbers, which will differ to the manufacturer's or international part number. But in this case the PSA part number has not been superseded, and looks already to be the international part number, so looks to be incorrect on the face of it.

[John1966]

Thanks again Marc
I've ordered both versions so will wait and see when they arrive.
Presumably will need coded so better investigate and see if my autel will do!

[GiveMeABreak]

There's nothing I can see that mentions this John, but you do have the Ford Puma engine and related systems, so not a PSA vehicle as such...
