I have a Peugot expert van and the anti pollution system fault warning light has come on and its very sluggish

Read OBDII codes to isolate problem https://www.6ya.com/callphilipforhelp

Disconnect batt a min....see if it clears. May need it hookd to a scanner to tell issue. Emmisions can effect motor and computr

bad o2 sensor

Have someone read the codes. check for any damaged vacuum hoses or electrical connectors left unplugged

anti pollution fault with fault codes poo87 poo93 i changed fuel filter, so far all ok.

Anti pollution light, I never heard of a Check engine light being called that.
Read on please.

Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

I had a problem with "Unblock diesel filter and Anti-pollution fault". After reading a few answers for this I decided to take car into the mountains for a good workout. Usually my trips are short and often therefore the exhaust was not getting hot enough to burn off the diesel residue in the Particle filter. In 40 mins of 3,5000 revs mainly in 3rd gear nothing showed up on the computer. Think this problem is sometimes caused by the engine not getting hot enough for long enough.

If the Anti pollution warning light is coming on the possible causes are endless. If the car is driving ok then that is a good sign, but please remember that modern management systems can mask problems quite well. The safest advice is to get it looked at and see what fault codes are appearing and then a diagnosis can begin, as leaving it is not going to be a good thing, it can go from a minor problem to more serious issues. At least the light is not flashing, which usually means an emission compliance problem and even more serious, but even so I would advise protecting your vehicle by getting it checked out as soon as possible to avoid potential damage.
----------
A fault in the ignition can cause an engine misfire and unburnt fuel gets into the exhaust causing the anti-pollution light to be triggered.

Check the ignition system for signs of damp or loose connections.------- I suggest get the car scanned at autozone service center.Its absolutely free to get car scanned.This will show the problem if you receive the error code.-------- Thanks.Helpmech.

clogged emission system could just be a line up to the whole exasut system
