The DPF pressure reading is present but implausible. Before condemning the filter, check the pipes and the sensor.
P2453 — also written P2453, P 2453, 2453 — is the OBD-II code for dpf pressure sensor range/performance. Same code, same fix: this page covers every spelling of it.
P2453 is a emissions fault code, typically costing £60–£500 to put right in a UK garage.
What causes P2453?
- Soot-blocked or kinked pressure pipes
- Failed sensor
- Genuinely blocked DPF
- Sensor reading offset when cold
How P2453 is fixed
- Compare the sensor reading at rest — it should be near zero with the engine off
- Clean or renew the pipes
- Replace the sensor, then reassess the DPF
P2453 repair cost in the UK
Most P2453 repairs land between £60–£500 including parts and labour. The spread is wide because the cheap fix (a sensor, a hose, a leak) and the expensive fix (a major component) throw the same code — which is why a proper diagnosis before parts are bought saves the most money.
Can you drive with P2453?
Yes, but plan a long run and get it checked before the filter blocks fully.
Urgency: medium.
