Particulate Filter Pressure Sensor A Circuit Range/Performance

Where it lives

For P2453, the description names the sensor as the part involved.

Check these first

• A particulate filter pressure sensor A reading outside its expected range
• A blocked or kinked sensor A hose
• High resistance in the sensor A circuit
• A failing pressure sensor A element

What to do next

1. Read particulate filter pressure sensor A on a scan tool
2. Compare the reading to a known good value
3. Inspect the sensor A hoses for blockage or kinks
4. Measure resistance of the sensor A circuit
5. Replace the pressure sensor A if the plumbing tests good
6. Clear the code and retest
