2004 Peugeot 206 2.0 HDi - Antipollution fault - stevejoneshfd

My Peugeot has been displaying this message on the dash, along with the engine check light. There are loads of posts related to this fault, and it seems to be a generic message.

I've used my mate's fault code reader, and P0102 is the only generic code that comes up, which is low voltage the MAF sensor? I removed and inspected the sensor, and found corroded (and a broken) terminal inside... so bought a salvaged (working) part and replaced. but the fault still remains.

What are the next steps to try?

Thanks in advance for any assistance :)

Was your mates scanner Peugeot diagnostic?

Because you just get missleading junk from anything except pugs own systems.

So my first step would be get it scanned with"Diag box"

No, it was just one of those hand-held ones you get from Amazon.

I was wondering if anyone had a wiring guide so I can check voltages to the sensor (to rule out bad earths, etc.) - its the 5 pin sensor on mine.

Can a bad battery cause this? It is quite an old one, it's been on there for at least 5yrs or more.

Sure a bad battery can cause all kinds of problems,

AS for wiring Peugeot use a number system for wire ident,

but your MAF should have numbered terminals.

T3 is ground

T2 is a shared fused feed.

And I'm repeating myself here,

Get it scanned with Diagbox.

Thanks, Hardway,

I'll check i've got power and ground from the terminals, and also what voltage coming out of the battery.

Should any reputable garage offering diagnostics have diagbox? It's not just the main dealers that have this?

You'd have to find a Peugeot specialist or a garage with top end diagnostics like Bosch KTS so a diesel specialist.

Not repeat NOT snap on diagnostics.

Peugeots are just hard to get accurate readings usuing other systems.

And though you might baulk at paying premium prices using inferior systems is a road to wasted cash in not needed parts.

Never discount the fact the salvaged part could also be faulty.

Google "Planet owners map" to find someone local to give it a proper diagnostic.
