04 2.0 HDi - Hall effect sensor - Firestormblue
Good morning.

I have been told i have a 'hall effect' sensor on the filling neck of my HDI car that may be faulty. (they cannot turn the 'diesel aditive minimum level' off?) Is there a way to measure or check this to test if it is indeed faulty? I'm handy with a meter...

Has the additive ECU been changed and what is the exact code number stored?

Er, no, and i didn't take note of the number. A diesel additive warning came on, so took it to my local garage. They put new additive in a little tank at the side of the fuel tank. They cleared all the codes and reset counters? But the code reader is saying there is no fuel cap fitted. I think. I can find out what the codes were by taking the car back. I think the code reader is a Snapon make...sulus, solus?

The counter won't reset without the cap sensor reading correctly. Have the magnets dropped off the cap?

No, mines a sw. I've been looking at that topic actually though. Seems they are having similar problems? It's from looking at that that i saw the cap had magnets. I didn't know that!

If the magnets are present; change the cap sensor.

As it's Hall-effect; it only reads on or off, depending if it's in a magnetic field.

On the filler neck; when the cap is fitted, one of the magnets is nearly touching it.

Just thought i would tell you what i have found out:
To test the hall effect fuel cap sensor, the readings are:
149 kohms (Cap on)
12 - 15 Ohms (Cap off)

Screwloose may confirm or shoot me down on this ( i think perhaps we've got off on the wrong foot)

I now also have a P1429 Particle filter pressure code. Going to try and test it tomorrow.

I'm sincerely sorry if i have offended anyone....
