Emission control system warning light stays on and warning of depollution system faulty displayed....what is the solution

You need an auto electrician to connect a pro grade scan tool computer and it will diagnose codes and communication errors that a cheap tool can't.

The Enhanced
Traction System
warning light may
come on for the
following reasons:


If you turn the system off by shifting to SECOND (2)
or FIRST (1), the warning light will come on and stay
on. To turn the system back on, shift to THIRD (3) or
AUTOMATIC OVERDRIVE (
). See “Enhanced
Traction System” in the Index.


If the Enhanced Traction System warning light
comes on and stays on for an extended period of
time when the system is turned on, your vehicle
needs service. Adjust your driving accordingly.


The warning light will come on when you set your
parking brake with the engine running, and it will
stay on if your parking brake doesn’t release fully.
If the transaxle shift lever is in any position other
than FIRST (1) or SECOND (2) and the warning
light stays on after your parking brake is fully
released, it means there’s a problem with the system.


If the traction control system is affected by an
engine-related problem, the system will turn off
and the warning light will come on.

It means that you must have the engine control module (known as the PCM) scanned for fault codes, this light can be turned on by literally hundreds of different faults.

Is there any fault indication on the dash where the radio display is.
Anti pollution is basically citroens way of saying emissions system so it could be as simple as a loose emissions pipe but from what you say and the car does not run it could be your catalytic converter (part of the exhaust system) has failed causing the engine management system to cut in and protect the engine.
If there is no fault apart from anti pollution showing in the radio display find someone with a diagnostic machine to give you a better idea of the fault. Hope this helps a bit.

Sadly a common fault with 207s is random fault warnings coming up on the display.

If it's a real fault, then you should notice a fall off of performance and this indicates a trip to your garage to get it fixed.

If the fault comes and goes, or there is no loss of performance, do what most 207 drivers do and ignore it !

P0453 means EVAP emission pressure sensor high input. Possible causes:
- Faulty Evaporative Emission System (EVAP) Pressure sensor
- Evaporative Emission System (EVAP) Pressure sensor harness is open or shorted
- Evaporative Emission System (EVAP) Pressure sensor circuit poor electrical connection.
Code p0701 means Transmission control system range/performance. Possible causes:
- Open or short transmission control system circuit
- Poor transmission control system electrical connection
- Check powers and grounds to Transmission Control Module (TCM)

Well its a 2009 and as such its all electronic control and it can only be diagnosed using the dealer software via the internet this is to stop people like myself from doing anything to it ,from the sound of it i would suspect the throttle position sensor under the dash on the end of the throttle pedal as this fault i have had before on more than one occasion even more so with my favourite )not( make of vehicle a renault but in all honesty you are in the hands of the dealers here as they are the only ones with access to the software via the internet with the factory ,Sorry i cannot give you a nice fixya easy type fix

Will be related to engine management in some way, it will need to be checked out by a specialist, might need the particulate filter regenerating££££

No I am a mechanic at Audi. The problem is that the the air flow to the central tappets may be causing the air flow sensor to trip and that is why. Try putting a small amount of WD40 into the petrol and that will work, its a very common problem.
