What does P1401 code 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.

How do you test a DPFE sensor?

How to Test the DPFE Sensor

1. Open the hood of the vehicle.
2. Disconnect the two vacuum hoses from the sensor by giving them a firm tug.
3. Turn the ignition key to the “On” position.
4. Connect the negative (black) multimeter lead to a ground point, such as the negative battery terminal.

Where is DPFE sensor on 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.

What does DPFE stand for on a Ford?

Differential Pressure Feedback Electronic
DPFE (Differential Pressure Feedback Electronic) Sensors are an integral part of the EGR (Exhaust Gas Recirculation) System. The DPFE Sensor provides information to the Powertrain Control Module (PCM) to tell it how much exhaust gas is flowing through the system.

How serious is a bad EGR valve?

A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration and decreased fuel efficiency. It can also cause vehicle emissions to increase.

How can you tell if the DPF sensor is bad?

Here are some signs that indicate the DPF is not regenerating properly due to the DPF sensor failing:

1. Poor engine performance.
2. Poor fuel economy.
3. High engine temperatures.
4. High transmission temperatures.
5. An increase in black smoke (soot) from the exhaust.
6. Check engine light.

What does code P1406 mean?

When code P1406 appears, the Exhaust Gas Recirculation (EGR) valve has failed. Cleaning the EGR valve can sometimes clear the code. It’s best to clean the valve before replacing the entire unit.

What happens if I drive with a bad EGR valve?

Driving with a bad EGR valve will mean that your vehicle will produce a lot of toxic gasses for the environment. Also, you won’t be able to pass the emissions test with a bad EGR valve. If cleaning the EGR valve does not fix your issue, take your vehicle to the mechanic and have it replaced.

Where are the fuses on a Ford Taurus?

Cigar lighter (power outlet) fuse in the Ford Taurus is the fuse #13 in the Instrument panel fuse box (2000). 2001-2003 – fuse #13 in the Instrument panel fuse box and fuse #18 in the Engine compartment fuse box. Since 2004 – fuses #25 and #29 in the Instrument panel fuse box.

What does P1401 mean on a Ford engine?

P1401 FORD Meaning The purpose of the Exhaust Gas Recirculation (EGR) system on your engine is to limit oxides of nitrogen (NOx) emissions. This is done by redirecting small amounts of exhaust gas back through the upper intake to get mixed in with the air/fuel charge.

What does dpfe sensor circuit high P1401 mean?

P1401 FORD | DPFE Sensor Circuit High | The purpose of the Exhaust Gas Recirculation (EGR) system on your engine is to limit oxides of nitrogen (NOx) emissions. This is done by redirecting small The purpose of the Exhaust Gas Recirculation (EGR) system on your engine is to limit oxides of nitrogen (NOx) emissions. This is done by redirecting small

Where are the fuses on a Ford Expedition?

The fuse panel is located below and to the left of the steering wheel by the brake pedal. Remove the panel cover to access the fuses. To remove a fuse use the fuse puller tool provided on the fuse panel cover. Identifying fuse panel. Fuse box diagram.
