Fault won't clear on ECU

by **bigyinuk** » Tue Jan 23, 2018 5:00 pm

Morning all

Does anyone have an answer to this?

I have a weird situation where an intermittent fault is showing on the ECU but will not clear with any diagnostic tool (inc Peugeot Planet).

When it gets to the point of clearing, there'a a weird humming noise from the car and the fault doesn't clear - Planet does not even create a new "service zone".

The car is a Peugeot 206 1.4l with Sagem S2000-2A

Is there any way to remove this by directly editing the ECU?

Regards

i dont mean to sound rude but the only time this has ever happened is when the faults not been fixed.

Fault code?

you have reached max 50 dtc in eeprom, read eeprom and two choices, virginize and adapt or erase dtc counter.

Nope, its only on 40 service zones, so should be able to create another 10. And in any case Peugeot Planet says that once all the service zones are used up, it is still possible to clear faults, just won't create a service zone record in eeprom.

Fault code is P1034 upstream oxygen sensor intermittent (caused by an injector fault now fixed).

A "Snap On" code reader was able to clear the last fault (39) but no other readers/tools would, including Peugeot Planet.

Bit stuck now and not sure what to do.
