    Thanks for sharing. I have an 05 trafic showing low fuel pressure and started cutting out friday. Drive few minutes and it cuts out again. Very hard to start it. I changed the fuel filter but no better. This looks like it could be the culprit.

    Hi Peter, could this problem with the sensor cause the van to idle but not rev when warm? It does eventually rev but I notice the idle speed is low then gradually creeps up to about 800 RPM then it will rev ok, or if your on a hill and increase the RPM in gear that way. I'm waiting for a new accelerator pedal thinking it could be that. Thanks

    If yours is the 1.9d engine, the most common issues with them running wise is EGR valves & Airflow meters. But both of them normally create fault codes, have you a EOBD code reader ??

    @@kennedysgarage3281 yes it is the 1.9 thanks for the reply. I’ve blanked off the EGR and tried 3 different MAFS. No fault codes register. I’ve ordered a the pedal to see if that works, but as the fault seems to happen mostly when the engine is hot I don’t think it will solve the problem. It wouldn’t happen if I could increase the idle speed.

    I have a 1.9 Diesel Renault Trafic '06. Disconnecting the pressure sensor and probing with a volt meter, gives me 5 volts on pin 3 , when pin 1 is ground. Now, when I probe the middle wire of the connector, I get 15 mV D.C and not the 4.9 volts that you recorded. Any ideas? Thanks ? Do you think I should change the pressure sensor ?

    It sounds like you have a broken signal wire or it is shorted to ground. You will need to do the same test at the ECU connector & see the results, that could be interesting 🤨 Let me know what you find please Jack 🤔👍
