This summary uses the existing diagnostic information shown in full below.
The car has a sensor that checks how much stuff is blocking the filter that cleans the air from the engine. This sensor is not working properly all the time.
The code P2CE9 indicates that the sensor monitoring the pressure in the particulate filter is sending inconsistent or erratic signals.
The particulate filter pressure sensor C circuit is responsible for measuring the pressure difference across the diesel particulate filter (DPF). This code means that the sensor is providing intermittent or erratic readings, which could affect the vehicle's ability to monitor and manage emissions effectively.
• Check Engine Light illuminated
• Poor engine performance
• Increased emissions
• Faulty particulate filter pressure sensor
• Wiring issues such as loose connections or damaged wires
• Faulty PCM (Powertrain Control Module)
Particulate Filter: A device that removes soot from diesel engine exhaust.
PCM: Powertrain Control Module, the vehicle's onboard computer.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the particulate filter pressure sensor for proper operation.
• Replace the faulty particulate filter pressure sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-250
• Chevrolet Silverado
• Ram 2500
• Regular maintenance of the DPF system
• Ensure proper sensor installation
• Avoid short trips that prevent DPF regeneration
Sensor Issue
• Have the vehicle inspected by a professional if the Check Engine Light is on.
• Do not ignore the issue as it can lead to more serious engine problems.
• Consider regular maintenance to prevent future issues.
Check with the vehicle manufacturer for warranty coverage on emissions-related components.
This code has been associated with diesel vehicles equipped with DPF systems since their introduction to meet emissions standards.
Moderate – It should be addressed soon to prevent further emissions issues.
Ignoring emissions-related issues can lead to failing emissions tests and potential fines.
• Engine running
• Vehicle at operating temperature
The particulate filter pressure sensor is typically located near the diesel particulate filter in the exhaust system.
Q: Can I drive with a P2CE9 code?
A: It's not recommended to drive for extended periods with this code, as it can lead to increased emissions and potential engine damage.
Q: How do I clear a P2CE9 code?
A: The code can be cleared with an OBD-II scanner after addressing the underlying issue.
