P2CEE: Particulate Filter Pressure Sensor D Circuit Intermittent/Erratic

The ECM detects a circuit intermittent/erratic fault on the particulate filter pressure sensor d. Reading cannot be used reliably for control.

Symptoms

• Check engine light or DPF warning light on
• Power loss / limp mode
• Increased fuel consumption
• Failed forced regeneration attempts

Most likely causes

• Sensor connector not seated
• Noisy ground reference
• Connector with intermittent contact under vibration

What to check, in order

Start with the simplest. You can tick off each step.

1. Read the soot load and differential pressure with a scanner
2. Gently move the wiring with the engine running and watch whether the reading changes.
3. Check the differential pressure sensor's hoses
4. Check the temperatures before and after the filter
5. Fix any fuel injection or EGR codes before regenerating
6. Perform a regeneration while driving or at a repair shop when the diagnosis allows it

Good to know

• Repair difficulty: easy
• It affects emissions.

What each character of P2CEE means

• P: Powertrain: engine and transmission
• 2: Generic code: same on every make
• C: Subsystem depends on the code range
• EE: Specific fault in that system

Frequently asked questions

Can I keep driving with code P2CEE?

If the light is on steadily, take a highway drive or go to a repair shop soon. If the car is in limp mode or the light is flashing, do not push the engine.

What causes code P2CEE?

The most common causes are: sensor connector not seated; noisy ground reference; connector with intermittent contact under vibration.
