Drivers of Ford cars may come across the dreaded Ford Code P1405, which can be troublesome to diagnose and repair. This code is associated with the DPFE (Delta Pressure Feedback EGR) Sensor. It is triggered when the PCM (Powertrain Control Module) detects an EGR flow in a negative direction, which typically means that the EGR valve is closed. To check for the cause of this code, you should check for any signs of icing in the upstream hose or wrong hose routing. The common reasons for this code are a disconnected DPF EGR sensor, a plugged DPF EGR sensor upstream hose, and a blocked or damaged EGR tube.

Causes and Solutions for Ford Code P1405
| Cause | Solution |
|---|---|
| DPF EGR sensor upstream hose is disconnected | Check hose connections and reconnect if necessary. |
| DPF EGR sensor upstream hose is plugged (ice) | Thoroughly inspect and clean the hose or replace if necessary. |
| EGR tube is plugged or damaged | Check for signs of damage and replace if necessary. |
| PCM indicates EGR flow in a negative direction | Check the EGR valve and replace it if necessary. |
If you’re the owner of a Ford car and experiencing issues with Ford Code P1405, then you’re likely facing a difficult task in diagnosing and repairing the problem. The code is associated with the DPFE (Delta Pressure Feedback EGR) Sensor. It is triggered when the PCM (Powertrain Control Module) detects an EGR flow in a negative direction, which typically means that the EGR valve is closed. To check for the cause of this code, you should look for any signs of icing in the upstream hose, or wrong hose routing. The three most common causes for the Ford Code P1405 are a disconnected DPF EGR sensor, a plugged DPF EGR sensor upstream hose, and a blocked or damaged EGR tube. While this problem can be difficult to diagnose, with the right knowledge, you can repair it quickly and efficiently.

Disconnected DPF EGR Sensor
If the DPF EGR sensor upstream hose is disconnected, you’ll need to check the connections and reconnect them, if necessary. Make sure that the hose is properly connected to the EGR tube and the EGR valve, and check for any signs of damage. If the hose is damaged, you must replace it before proceeding.
Plugged DPF EGR Sensor Upstream Hose
If the DPF EGR sensor upstream hose is plugged, you’ll need to inspect and clean it or replace it if necessary. You’ll also need to check for any blockage in the hose or EGR tube, as this could be causing the problem. If you find any blockages or obstructions, you’ll need to remove them before you can continue.
Plugged or Damaged EGR Tube
If the EGR tube is plugged or damaged, you’ll need to check for any signs of damage and replace it if necessary. You’ll also need to check that the EGR valve is working properly, as this could be the cause of the Ford Code P1405. Once you’ve identified and repaired the source of the issue, you can reset the code and continue driving your car.
