Peugeot 207 1.6 9HZ 2007 - Cutting out, code P0192 fuel rail pressure sensor - Fixed #

Posted by Shane Marc Gray on August 22, 2017, 8:34 pm

Year of Manufacture *: 2007
Engine Size and Code *: 1.6 9HZ
( Optional ) Scanner Used: Modis
( Optional) Fault Codes: P0192

Hi guys ,

Fault code P0192 fuel rail pressure sensor low short to ground.
Live data shows fuel pressure 260 bar at idle and when engine cuts out it doesn't drop ! Tryed scopping signal wire on pressure sensor (at ecu as can't get at sensor), but I,m not getting any signal , which is strange as live data is reading pressure.
Fuel filter checked, injector leak offs checked, in tank filter checked and all fuel lines.
Any advice please ? And why no voltage from signal wire on pressure sensor?

Regards Shane

Check the wiring.

pressure reading a subistuted value ?

or a limitation of the scan tool

check wiring as kevin said

"or a limitation of the scan tool"

Could be that,s the problem posting limited info,

Much preferred the forum when it had a posting guide.

Always post as much info as possible, it will get read IF it,s long and has ALL the info.

I give short replies to posts that lack details , so what scan tool ?

Morning,
It does say modis on my first post, also tried Mech 5 .

Managed to get a scope reading Friday and pressure drops to 0 volts when fault occurs.Have load tested all 3 wires on pressure sensor to ecu and all good.

Have changed fuel filter , checked
In tank filter and all pipes, leak off on injectors done.
On Tuesday going to give own fuel supply and scope pressure reg !
Also scoped crank sensor when fault occurs and that's also good.

Regards

Shane

Would it actually run at all if it didn't see any fuel rail sensor input at ecu.

Are you sure you've a good contact at ecu pin or on correct wire.

I've done this myself and found out it's the back probe not making contact.

Hi Lee,

That's what I thought so on checking it again Friday had a pattern . When it cuts out drops to 0 volts . Explained better in last post .

I'm seeing more FPS faults on these 1.6hdi engines nowadays.
I have learn't the hard way that the ecu or scan tool (I use either Bosch KTS or Mech5 on these) will give the last known good reading or a substitute value when I know it should be reading zero.
I have read elsewhere on this forum that the FPS connectors wear/work loose, so I now keep a couple of these in stock and is my first stage of repair.
(after confirming the integrity of the wiring )
Delphi part number 9001-930

Hi

I to have seen FPS faults, reasonable price for diesel specialist (£30 from memory.

Agree with comments on live data, if fault code present it will be a substitute value.

I feel this is a 'circuit' fault as would expect to see approx 0.5 volts even at zero pressure.

so would be looking at wiring on sensor myself

be carefull as sometimes a bad EGR sensor can cause a engine to cut out. This is because EGR position sensor and fuel pressure sensor share the same 5v. feed. Try to unplug EGR and see if fault reocurs.

Evening,
Thanks for all the responses, it was a bad connection on fps as when I plugged it back in after testing resistance in wires to ecu , the fault disappeared. I haven't replaced the connector only informed customer if problem reoccurs will fit new one.

Thank you

Regards

Shane

Glad to hear it's fixed.
The first time I came across this it had me going round in circles.
