How do you know if the DPFE sensor is bad?

When the DPFE sensor fails, the engine can’t run as it was designed. With a faulty sensor, the wrong information is sent back to the engine’s computer. Because of this bad data, the EGR system malfunctions. With this system not running properly, you will notice reduced power and a rough idle.

What’s a DPFE sensor?

MOTORCRAFT® DIFFERENTIAL PRESSURE FEEDBACK (DPFE) SENSOR The DPFE Sensor provides information to the Powertrain Control Module (PCM) to tell it how much exhaust gas is flowing through the system. The PCM uses this information to control the EGR Valve and other factors to optimize engine performance and emissions.

What does code 1401 mean?

Error Code P1401 is defined as DPFE (Differential Pressure Feedback Sensor) Error. This error code is a manufacturer-specific trouble code, meaning it does not apply to all vehicles makes. Rather, it applies only to specific vehicle makes, such as Ford and Hyundai.

Can you clean a DPFE?

I cleaned them both with a wire brush and carb cleaner. Let the entire mess dry out after spraying some compressed air in each passage and cleaning out the tubes as well. The results: Don’t waste your time! Put the DPFE back in and reconnected the tubes and drove the car for 25 miles …

Where is the EGR sensor located?

Mechanical EGR valve position sensors are mounted on the top of the EGR valve. EGR pressure sensors will be located close to the EGR valve as the exhaust gas hose must be connected to the sensor as well as the valve.

Where is the differential pressure feedback sensor?

Differential pressure is essentially the difference in pressure between two given points. It is a type of pressure measured within different industries using differential pressure sensors. Gauge pressure refers to the difference between a measured point and the atmosphere.

Where is the DPFE sensor located on a Ford f150?

Locate the DPFE sensor. It is positioned to the left of the brake booster up against the firewall and has two metal tubes running from the EGR valve supply line and into the DPFE sensor. Note that some sensors will “float” above the tubes, while others may actually be fixed to the firewall by (2) bolts.

How do I fix error code 1401?

Is there any way to fix the 1401, 1687 and 1485 support codes?

1. Ensure both a black and colour cartridge are installed.
2. Check the cartridges have the correct codes.
3. Make sure the contacts are clean.
4. Replace the defective ink cartridge.
5. Clean the contacts inside the printer.

How do I bypass the code 1688?

Support Code = 1688 The ink has run out. Replace the ink cartridge and close the paper output cover. If printing is in progress and you want to continue printing, press the machine’s Stop button for at least 5 seconds with the ink cartridge installed. Then printing can continue under the ink out condition.
