Hi.

Ive got a faultcode p2452 "diesel particulate filter differential pressure sensor circuit".

Anyone here have som more info about it? Is it the sensor itself being faulty? If so, is it easy to repace by myself?

Okey, so I think I found the problem:

I cant imagine the left hose ending up in thin air, the bad thing is I cant find the other end that's coming up from the DPF.

Suggestions on where it might be? I dont even know where it's supposed to come up into the engine area.

The controllamp did not light up after starting the car today. I resetted the fault code but I got the same one again instantly.

 

Regards,

Kim.

does a DPF have rubber hoses on it? its in the exhaust system, metal pipes, etc....

It does on my Octavia, the two pipes which to the differential pressure sensor from the different are rubber.

Here you go, a common fault, looks like the G450 sensor has had it...

Possible Causes

• Fuse(s) faulty

Wiring and/or Connector(s) from/to Exhaust Pressure Sensor 1 (G450) faulty

Exhaust Pressure Sensor 1 (G450) faulty

Possible Solutions

• Check Fuse(s)

Check Wiring and/or Connector(s) from/to Exhaust Pressure Sensor 1 (G450)

Check/Replace Exhaust Pressure Sensor 1 (G450)

• Check Measuring Values

Well, had the car turned in to the repair shop the day before yesterday.

The sensor itself cost around £90 and the change, calibration and reset of the fault code cost me £20.

All good now

Thanks for the input.
