Hi guys,

My car recently displayed an 'Air pollution system faulty' message whilst driving.

I bought a Peugeot Planet kit and the car is displaying the following error codes:

---
P1498 Air metering valve

Status: Permanent fault
Characterisation: Position incorrect (too closed) (after sales)

Engine speed: 2240 RPM
Air metering value position setting: 0%
Air metering valve position copy: 43%
Accelerator pedal position: 28%
Measured air flow: 1000mg/impulse
---

P0488 Air metering valve

Status: Intermittent
Characterisation: Position incorrect (too closed)

Engine speed: 2976 RPM
Air metering value position setting: 0%
Air metering valve position copy: 51%
Accelerator pedal position: 92%
Measured air flow: 1223mg/impulse
---

P2141 Control of the air mixer
Characterisation: Short circuit to earth

Status: Intermittent
Engine speed: 0 RPM
Air metering value position setting: 100%
Air metering valve position copy: 4%
Accelerator pedal position: 0%
Measured air flow: 588mg/impulse
---

Ideally I want to be sure exactly what is wrong and what needs to be done before taking it in for repair (if possible and not too involved, I'll do the work myself).

Still looking to get this resolved if anybody more knowledgeable can shed light on it please

Hi,

Did you manage to resolve this issue? I have the same 3 fault codes on my 2010 2.0HDI 3008.

When it first happened before X-mas I cleared the codes and they didn't come back for months. Its happen half a dozen times now and its now only 500 miles between the last two.

Apart from being annoying I have experienced no performance issues though I don't want to cause any longer term damage to the car.

There's a valve/throttle flap on the back of the intake manifold, that may be sticking

 

[Heisenberg]

Yes, still have this issue. I have actually started to notice a momentary shudder/loss of power around the 2000RPM range, although this is pretty intermittent and lasts perhaps a second. Still don't want to leave it like that though.

jimmymarsbar, thanks for your reply. Is this a bit of a pain to get to on this car? Guessing it's towards the back of the engine bay? Assuming I can get to it, is it a quick fix or will it likely require parts to be ordered? Appreciate this may require a 'how long is a piece of string answer' without looking at it

I ran the 'Movement of the Air Mixer' actuator test half a dozen times. On some occasions the car stalled and and other the revs dipped to near stalling. The first message I got mentioned it was blocked and subsequent time I got 'Test Stopped'.

After the test P2125 Air meter valve code returned (though not check engine light) which I cleared.

Car still runs fine but as previously mentioned the check engine is returning more frequently.

I wouldn't know how to locate the 'valve/throttle flap'. Any further assistance would be appreciated.

If I end up taking it to a garage I will share the outcome.

I tried accessing the intake manifold but it's an absolute nightmare to get to in this car, due to the way the engine bay is recessed back into the dash area. I suspect you may even have to remove the engine to get access to it, but not 100% sure. Put it back together and have left it alone since.

turf, was that test an option in Peugeot Planet? I didn't see it but may have missed it!

 

[turf_layer]

it was in diabox when fault finding, under the engine ecu. click on actuator test then 'while the engine is running'. you should then see the test.

Theres a Peugeot specialist not far from where I live so I might take it there at some point. As the car is running fine at the moment the only annoyance is the warning light/ bleep though I am wary of doing any long term damage. FYI the car is approaching 100k miles.

Did one of you found out how to solve the p2125 error with air mixer?

Any luck with that issue?

I replaced the air mixer. That removed the p2125.
