Hi mattdehat, no. It is not possible to tell you what part to change from that error code. That is not how error codes work.

The MAP sensor is found on some of the diesel engines fitted to the C3 and you will find it on the air inlet ducting.

This is what is looks like on a 1.4 HDi 16v but the same part is used on different engines.

The map sensor monitors intake pressure and a map fault indicates the ECU has found an unexpected reading and this could be due to a number of reasons additional to a faulty sensor.

If you have a 1.4 with no DPF or FAP then any dog cleaner you add to the tank will have no effect because there is nothing for it to act on.

The DPF is an exhaust system part and will give different errors and not an inlet error that you have.

I don't think DPF cleaner will help you here :(

No DPF in that VIN.

You code is not a DPF fault.

The way forward would be to

Connect the car to Lexia tool (info here) to get the correct description for this code and any solutions that lexia suggests. Generic code readers can be wrong with the Diesel C3 engines.

and/or

check the inlet system- air filter, intake pipes etc.

Identify if you have a MAF fitted - as shown in the photo.

Check the wiring to the MAF, check the connections on the plug/socket of the MAF.

Check back to the engine ECU there are 3 main plugs and these can give poor connection.

Check the loom for damage - not as easy as it sounds, you will need a wiring diagram to trace the MAF wiring back.

Try a working sensor in there, try your sensor in another C3 to see if the problem moves with the sensor.

Try resetting the code.

(quote myself :lol: )
According to my diagram, yes, you should have one. So check this looks ok, there is an associated pipe for the MAF sensor, so check this is ok and not dislodged or damaged.

The Barometric sensor is usually inside the engine ECU and not a replaceable part (other than replacing the whole ECU).

Lexia can do a live data on the MAF sensor and Barometric sensor to see which one is giving a out of band reading.

Update....after filling up with premium diesel and giving the car a 200 mile round trip the anti pollution error has gone,i am thinking that this problem was due to the car doing super short journeys and not giving the car enough time to regenerate its gases ect.i may be wrong but fingers crossed all is good again.id like to thank everyone who helped me .CHEERS guys.awesome forum.......
