PMS sensor

If PMS means particulate matter sensor in your case, you will probably have check engine warning when switching on and an yellow/orange warning light permanently showing.

My 21 plate Ducato base pvc has had a PMS warranty replacement on order for the last month. It had done fewer than 2000 miles when the error first showed up but it's done another 1500 since with a permanently illuminated engine warning light and no other problem.

Hi all, the dealer should have provided a diagnostic print out of the fault codes extracted from the vehicle some are permanent and cant be erased till the fault is fixed, other codes which illuminate your dash are some times caused by a temporarily or intermittent glitches can be erased i have Peugeot Diagbox and Fiat multiecuscan software the initial outlay  paid for itself educated and fixed faults which were on the vehicle when bought from new it is not always component failure which illuminates warning lights the only sure way is  the diagnostic evidence, the repairing dealer should explain this but in my case this did not happen but i never intended relying on the warranty which is a shame, hope this helps some.

Yes, Pete, to the warning light. We were on our way back from Cornwall but managed to get home safely. 

The motor had to go back to the dealers anyway because the step wasn't retracting properly and had to be immobilised.

They have had it at the dealers since.  Unfortunately they are over an hour away from where we live or we might have risked local area breaks.

No, Chris and Malc, we didn't get a diagnostic print out. The travel distance has meant we have to rely on phone calls. Even then we only get to speak to an intermediary, never the actual service engineer. 

It's causing a lot of frustration as you can imagine.

Anyway thanks for your input, much appreciated.

Hi, in my case i established early on that the dealer for my new motorhome did not have the facility or knowledge to diagnose the base vehicle diagnostics and was not interested and advised to take it to the Peugeot main dealer, if you are like myself and keeping the vehicle it is most beneficial to look at and become familiar with Fiat Multiecuscan even if you want repairs done under warranty or at a later date you will be better informed and in lots of cases the only way to clear faults and extinguish most warning lights is with Multiecuscan. Warning triangle with perhaps check stop lights EXAMPLE will clear itself as that is on a different bus or circuit i got up and running for under £100.00 i'm your man for Fiat Multiecuscan

Hi, did you manage to get this part from Fiat? We took our van to Fiat for it's first MOT, on picking it up the engine warning light was on, they diagnosed the fault as a DPF pressure sensor. We have now been waiting since Dec 22 for a DPF sensor, which I feel could be a different term for the same part as yours.

Does anyone know if there is a work around or alternative part? I have taken my van to a couple of independent garages who seem unable to help. 

Many thanks

I think that you will find that many garages fit a spacing washer between the exhaust and the sensor to reduce its sensitivity. I’m not commenting on the rights and wrongs because I see it as a ‘get you out of a fix’ solution. 

Hi the same thing has just happened to myself we have a fiat Ducato on 70 plate done 7000 miles engine light came on and no stop start been to local garage had a diagnostic report of vehicle showing particulate matter sensor going to fiat at chesterfield hopefully they’ll sort it stuart please if anyone can get in touch about this problem please can you phone me  many thanks stuart
