P2453 OBD-II Trouble Code: Particulate Matter Trap Differential Pressure Sensor Signal Performance

Check Engine Light

P2453 code definition

Particulate Matter Trap Differential Pressure Sensor Signal Performance

What the P2453 code means

This trouble code will only appear on diesel engines and it indicates that the powertrain control module has detected a voltage reading from the fuel filter pressure sensor that is outside the range of acceptance set by the vehicle manufacturer.

What are the causes of the P2453 code?

Some of the potential causes of this trouble code would include:

  • The fuel filter could be clogged or saturated to the point that is is breaking down (this would indicate that it was not changed at regular intervals).

  • The fuel filter pressure sensor could be faulty.

  • Wiring or connectors associated with the fuel filter pressure sensor could be damaged.

  • The powertrain control module could be malfunctioning.

What are the symptoms of the P2453 code?

Symptoms of this trouble code being stored that the driver could potentially experience would include:

  • The Check Engine Light would likely be illuminated.

  • If this code is stored for a long period of time, it could potentially cause a no start condition. This code works almost like an indicator that the fuel filter should be replaced.

  • There will likely be no drivability symptoms from this trouble code.

How does a mechanic diagnose the P2453 code?

A mechanic would first start the diagnosis of this trouble code with an inspection of the fuel filter. If the fuel filter has dirty fuel in it or seems to be clogged or restricted, the mechanic would replace the fuel filter, reset the codes, and verify the repair.

If this did not resolve the issue, the mechanic would then check the wiring and connector that are associated with the fuel filter pressure sensor to determine if any damage exists. If any damage exists to these wires, repair or replacement would be required.

If the wires to the fuel filter pressure sensor seem to be okay or if fixing the wires did not resolve the problem, the mechanic would then test the fuel filter pressure sensor using the manufacturer’s suggested procedure. If the fuel filter pressure sensor is faulty, it would be replaced.

The final test the mechanic would perform if necessary would be a powertrain control module function test. This would determine if the powertrain control module was performing correctly. If not, it would likely require replacement.

Common mistakes when diagnosing the P2453 code

The fuel filter pressure sensor is often replaced in error when a fuel filter is the actual cause of this issue. The fuel filter should always be the first thing that gets looked at when diagnosing this issue as it is the most common cause.

How serious is the P2453 code?

This code would not be considered serious unless it was allowed to be stored for a long period of time. If this issue gets diagnosed and repaired quickly, this code should have no lasting effects at all.

What repairs can fix the P2453 code?

Repairs that can potentially resolve the issues caused by this trouble code would include:

Additional comments regarding the P2453 code

If the fuel filter is clogged, this can cause excess back pressure in the fuel line and potentially damage the fuel pump. Just with any Check Engine Light, it should be diagnosed and repaired quickly.
