308SW fault P1586 ?

[ianmcc]

Hi there,

Out on the road without any warning the engine stopped. Once parked up, it would restart, but then stop again. Then it would not start and it was Recovery time (Great job Green Flag !) to get home (200+ miles).

P1586 : Rail Pressure, flowmeter, EGR valve copy sensor supply

Doesn't give much to go on .... anybody had one of these ? Thanks ............

This should provide some more info for you:

Fault Code:	P1586
Description of Fault:	5 V sensor supply (N°3) for the rail pressure sensor, air flow sensor and EGR valve repeat: Supply voltage too low. The supply common to the pressure sensor of the fuel high pressure common injection rail, to the flowmeter and to the EGR valve copy is lower than 4,7 V for 150 ms.
Conditions for Fault to clear:	Ignition on
Downgrade Modes whilst Fault is active:	Default value for the air flow as a function of the engine speed and of the flow injected Inhibiting of the diagnostics and air flow sensor plausibility Use of the flow calculated Cut of all the actuators: Motorised exhaust gas recycling valve (Turbocharger air cooler); Exhaust gas recycling valve; Bypass valve (Intake air heater ) In all operating modes. Switching on of the warning lamp and/or warning message: Warning lamp MIL
Symptoms:	Jerking/stalling Lack of power Starting problem
Suspect Areas:	The sensors sharing the power supply are as follows: Electrical harness Connector Engine management ECU (internal failure, supply, ...)

1310 : air flowmeter
1321 : diesel high pressure sensor /
1297 : Electric EGR valve
1221 : diesel fuel thermal sensor /
1361 : turbocharged air heater electrovalve 1
1362 : turbocharged air heater electrovalve 2
1115 : cylinder / reference sensor /
1313 : engine speed sensor /
1208 : / diesel injection pump
1220 : engine coolant temperature sensor
1240 : induction air temperature sensor
1312 : inlet air pressure sensor

Thanks, Marc, that's great I don't have access to this type of material.

Still leaves a bit of work to do - it starts today and runs OK parked up - and the engine light (orange) has gone out - not the kind of gremlin I like looking for. I'll start by assuming it is a connector fault somewhere.

Once, on my Berlingo the throttle cable gave up when I was overtaking. It was nearly the end of me. This makes me very (very) nervous of engines that just cut out !

[GiveMeABreak]

Well hopefully there's something there to get started with - always go for connectors and the pins on them especially, as these can move, become loose and then contact is intermittent.

[ianmcc]

Thanks, Marc, getting there - two quick questions if I may :

Colour codes - is there one for these cars. 5V = ?
BSI Reset - I've got a BSI F55F 're-initialisation' error, will it fix this ? (Assuming battery disconnect is only a 'soft reset' and this is a 'hard reset')

Thanks, Ian

No, don't use colour codes as the wiring colours often change en-route. Always go by the wiring code printed on the sleeve every so often as per the electrical diagram.

Take 1310 (Air Flow Meter):

6V NR means it's a 6 Pin (6V) Black (NR) Connector
Pin 1 is 1340 : air temperature at the air flow sensor signal
Pin 4 is 0003 : the supply from the engine Fuse box (PSF1)
Pin 5 is 1333 : inlet air flowmeter signal
Pin 2 is 1336 : air flow sensor earth

I think you mean F5FF, which is: Unexpected re-initialisation fault coming from the BSI: Not characterised. This is just what it says an uncharacterised fault, so there is not further info on it. I've seen it before loads of times, so just ignore it as there's nothing you can do about it.

But a BSI reset can sort out some gremlins BSI Reset / Battery Disconnect / Reconnect Procedure

[ianmcc]

Thanks Marc, yes I should have worked that out - trouble is where the cables are exposed on this car most of my numbers are lying around as black paint flakes.

OK, yes, F5FF - doesn't seem to be too serious.

Got down to the possibility of a corrosion short circuit in the EGR valve cap - as attached - doesn't look that bad. I'll replace it, but this a branded replacement EGR only fitted last year which doesn't inspire much confidence ................

[GiveMeABreak]

Does look like it's seen better days!

What brand was it as a matter if interest?

From a NAPA Motor Factor - Delphi it says - £150, or so .........

Apologies Marc, another couple of quick questions ...........

I've replaced the EGR, car is fine, but I'm getting the DiagBox EGR operational errors P0490/P1459/P0401. Just to confirm :

- when you run EGR Replacement in Pack Repair how do you know that the install has worked ? There is no 'Repair Successful' message, it just goes back up the Menu after the ignition on/off routine. Do you know if some check on the operational parameters is possible ?
- should the engine be running in Pack Repair ?

Thanks, Ian

Make sure the vehicle is not going into economy mode which it can do. I'm not aware of anything other than following the guidance in the repair menu.

Try a BSI Reset / Battery Disconnect / Reconnect Procedure in case the various ECUs are not initialising properly. Follow the timings and instruction not to open any doors or press any switches during the process as it will re-awaken the BSI again.

You may want to top up the car battery charge whilst doing this in any case to ensure that economy mode doesn't kick in too quickly.

Failing all that, if the errors are still coming back after you have cleared the fault codes after the pack repair operation, then it may be that your clone isn't working or the software. What version of Diagbox are you using?

A dealer visit to programme it may be the answer if the above doesn't work.

[ianmcc]

Thanks Marc, I think I am done now ... no serious faults showing (just P1351 which I don't think I am worried about)

I've got a copy of DiagBox from EasyDiagnostics - 7.57 - and aside from the 'no updates/no authentication' (because you are not connected to Peugeot) it seems to work fine. Sometimes, it seems, you have to do things x2/x3 things before they actually 'take' which can be a bit misleading.

In your 'BSI reset' is there a 'turn lights on' line missing ? and should this be sidelights, or headlights ?

Thanks for your help again .................., Ian

[GiveMeABreak]

Ok, so never use online mode with Diagbox, as it can deactivate the software. Make sure the WiFI connector is on (essential) but that the laptop is not connected to any active WiFi spots (so make sure you don't have automatically connect setup) otherwise it can deactivate as said.

Pleased you have it sorted, ignore the P1351 for now, that's to do with the glow plugs. The HDi only really uses these for very cold starting and also for assisting with particle filter regeneration when required for post-heating. Given the hassle of replacing these, you may decide to ignore it unless you live in the arctic circle.

Thanks for your Forum donation, very generous Ian, and also for the BSI omission. I think this got lost when I last updated it , so have now corrected it, thanks.
