P2453 is a diagnostic trouble code (DTC) for “Particulate Matter Trap Differential Pressure Sensor Signal Performance“. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

Where is the DPF pressure sensor located?

engine compartment

The DPF differential pressure sensor is usually mounted in the engine compartment to protect it from heat. The sensor is connected to the engine control unit (ECU) by an electrical connector and connected to the DPF via two silicon hoses.

What causes low DPF pressure?

A DPF pressure drop increases with increase in the soot mass accumulated in the DPF. Small soot mass accumulation results in lower DPF pressure drop, while high soot mass accumulation would yield higher DPF pressure.

Can you clean a DPF pressure sensor?

In order to burn it clean, the de-installed DPF is put in a burning oven, where it is heated until all remaining soot is burned to ashes. Subsequently, the filter is blown clean with pressurised air until all ashes are completely removed. Rinsing is in fact blowing the filter clean with a watery cleaning solution.

  2. Repairing or replacing wiring or connectors that are associated with the fuel filter pressure sensor.
  3. Replacing the fuel filter pressure sensor.
  4. Replacing the powertrain control module.

How do you fix a DPF pressure sensor?

Zitat von Youtube: There you can even follow the pipe work and see where it then goes into the the dpf. If we just take a closer look here you can see you got the hose clamps there they just need undoing.

How do you unblock a DPF filter?

If you get a warning light showing that the filter’s blocked, it should be possible to complete an active regeneration cycle and clear the warning light by driving for 10 minutes or so at speeds over 40mph.

How do you reset a DPF pressure sensor?

Zitat von Youtube: We can just select reset DPS at the bottom here and that would allow us to reset any vehicle. In case connectives like GM manual select we want DPF service reg ignition then we want chevy.

How much does it cost to replace a DPF sensor?
