What are the symptoms of a bad DPFE?

A faulty DPFE sensor can cause several problems:
  • increased emissions.
  • rough idle.
  • hesitation.
  • decreased engine power.
  • decreased fuel efficiency.
  • failed emissions.
  • check engine light on.

How do you test a DPFE sensor?

Open the hood of the vehicle. Locate the DPFE sensor, which is near the EGR valve, behind the upper intake manifold, between the firewall and engine. The sensor is a small square with two vacuum hoses on the bottom and a wire harness coming out from the side. The location will vary slightly from make and model.

What causes a DPFE sensor to melt?

As the pressure builds up, the engine exhaust temperature rises and will heat us the tubes that the DPFE registers and will cause it to melt.

How much is a DPFE sensor?

The cost to replace a DPFE sensor and EGR valve range from $150 to $500. The parts tend to make up the majority of the cost, usually between $100 and $400, while the labor might only be $50 to $100.

What does DPFE stand for on a Ford?

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 do you check DPFE voltage?

Attach the hoses to the sensor as normal. Now remove the rubber vacuum hose from the top of the EGR valve diaphragm. With the truck running apply slight vacuum to the EGR valve and this will open the EGR valve. When the valve opens you will see the voltage on the top wire of the DPFE sensor change indicating flow.

How do I fix code P0402?

What repairs can fix the P0402 code?
  1. Replacing the stuck open EGR valve.
  2. Replacing a broken catalyst in the exhaust.
  3. Replacing an EGR temperature sensor or cleaning the carbon off of it to repair it if it registers too much of a temperature change.
  4. Replacing the EGR backpressure control valve.

What is the code P0401?

What Does Code P0401 Mean? P0401 definition: Exhaust Gas Recirculation (EGR) Flow Insufficient Detected. Issue Severity: MODERATE – Extended driving with this code may cause internal engine damage. Repair Urgency: Get this code fixed as soon as possible to avoid internal engine damage.

What is code P1405?

OBD II fault code P1405 is a manufacturer specific code that is (according to some resources) defined by car maker Ford as “DPF EGR Sensor Circuit High Voltage Detected”, and is set when the PCM (Powertrain Control Module) detects a negative exhaust flow while the engine is running with the EGR (Exhaust Gas …

What does DPFE sensor do?

o 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.

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 EGR pressure feedback sensor?

The EGR pressure feedback sensor is generally found mounted somewhere on the engine or to the firewall.

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.

Can EGR cause misfire?

It is also possible for an EGR valve to leak, causing a random misfire. The next thing you should check is the fuel pressure with a gauge. In addition to leaking pressure, a bad fuel pressure relay can also prevent a good fuel pump from delivering full pressure to the injectors as well.

How does Ford EGR system work?

The EGR system works by returning a small portion of exhaust gas to the engine’s combustion chambers through the intake manifold, lowering combustion temperatures and therefore reducing the amount of NOx emitted. The EGR valve is the main component of the EGR system and it’s normally closed.

What can trigger an EGR code?

A clogged catalytic converter. Carbon buildup on the EGR temperature sensor. Faulty or lack of vacuum supply to the EGR. Electrical problems with the EGR circuit.
