807 Anti pollution fault

[sideswipe]

Hi just joined the website sorry if i have put this in the wrong section,
I have a 2003 907 2.0 hdi rht engine code with the engine light on.
Have got peugeot planet and read the codes are -

Engine ecu codes
per fault add heating circuit 1 open or short cuircut
per fault diff presure sensor signal coherance with vehicle stopped
remote per fault addative system faults addative pump
remote per fault addative system fuel cap sensor fault
remote per fault addative system fuel gauge fault
remote per fault addative system ecu fault
remote per fault addaitve system injector fault
remote per fault addative system addative accracy
int fault additional heating cuircut short or open cuircut
int fault addative quantaty addative ecu
int fault addative quantaty min level wait

Addative ecu faults- tank cap signal but changed sensor and cheched at ecu???? Cleaned all earth's all faults relate to sensors etc on the 10pr loom have had a quick look atconections on tank and sensor all ok any help???
have checked the multiplex wirring from engine ecu to bsi and from bsi to addative ecu all seem to be fine with no high resistance.

sorry 807 ot 907

Whats the diff pressure reading when ignition on..engine running at idle..2k 2.5k...if you have planet are you getting coms with additive ecu...?

hi not sure of the exact readings but were fluctuating when i reved it on peramiters of the diff sensor.

The comunication with the addative ecu is good and has only one fault code-
fuel cap signal.
have replaced the sensor and have checked the resistance at the cap sensor and the addative ecu all within readings and are the same in both positions, also in peramiters says prestant with the cap on and absent with the cap off. could it be a faulty addative ecu as the fault code is still presant.

Engine ecu codes
per fault add heating circuit 1 open or short cuircut common fault
per fault diff presure sensor signal coherance with vehicle stopped check diff pressure
remote per fault addative system faults addative pump Can you here the additive pump when you activate it with planetremote per fault addative system fuel cap sensor fault Has this fault cleared since you replaced the fuelcap sensor
remote per fault addative system fuel gauge fault Same as above
remote per fault addative system ecu fault whats the p-code

remote per fault addaitve system injector fault whats the p-code

remote per fault addative system addative accracy whats the p-code

int fault additional heating cuircut short or open cuircut common fault
int fault addative quantaty addative ecu whats the p-code
int fault addative quantaty min level wait Did you reset both counters after a addtive topup

Sounds like you additive ecu is corrupt..

Hi checked the diff pressure at 0 RPM and was giving 172mb i think and fluctuating around when reved, i had a new one so fitted and the readingsare now
0 RPM- 0 MB and 803 RPM 'idle' 5.9 MB 1500RPM 11.9 MB 200RPM 28 MB

The diff sensor fault has now gone (sensor was full of water on one side)

Cleared fault codes ran and tested, read fault codes:-
1. remote perm fault addative system,fault(s) addative pump P1435
2. remote perm fault addative system,fuel filer cap sensor fault P1435
3. remote perm fault addative system, fuel gauge fault P1435
4. remote perm fault addative system, addative adding ecu fault P1435
5. remote perm fault addative system, addative inj fault P1435
6. perm fault addative system fault(s), addative accuracy P1435
7. perm fault addative quantity, addative ecu P1442
8. perm fault addative quantity, addative min level wait P1446

I have not added any fluid as yet just in case the fault was with the addative pump/tank, most of the p code reads say addative level 1g in the fault discription/data.

The fuel addative ecu fault of the tank cap signa has cleared for now how long for i dont know.
Have activated every thing in the particle ecu menu all worked as it should but the addative injector clicked but that was it, should have knocked as per the discription.
