What are the possible causes of p1400 code?

P1400 Possible Causes 1 Differential Pressure Feedback Electronic Sensor harness is open or shorted 2 Differential Pressure Feedback Electronic Sensor circuit poor electrical connection 3 Faulty Differential Pressure Feedback Electronic Sensor

What is the dpfe sensor on Ford p1400?

The system employs an EGR Valve, an Electronic Vacuum Regulator (EVR), and a Delta Pressure Feedback EGR sensor (DPFE). The DPFE Sensor measures EGR flow across an orifice located inside the special EGR Tube.

How much does it cost to diagnose p1400 Ford code?

The cost of diagnosing the P1400 FORD code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. When is the P1400 FORD code detected? Differential Pressure Feedback Electronic (DPFE) circuit low voltage detected

What does differential pressure feedback electronic ( dpfe ) circuit low voltage detected?

Differential Pressure Feedback Electronic (DPFE) circuit low voltage detected 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.

How does the p1400 Mitsubishi manifold differential work?

This is done by redirecting small amounts of exhaust gas back through the upper intake to get mixed in with the air/fuel charge. The resultant diluted air/fuel mixture (i.e., less oxygen per cubic foot) burns cooler and combustion chamber temperatures are reduced accordingly, thereby lowering NOx emissions.

Where is the dpfe sensor located on a Ford?

The DPFE Sensor measures EGR flow across an orifice located inside the special EGR Tube. The orifice is positioned between two hose ports coming off the tube which are connected to the DPFE sensor with special heat-resistant hoses.

When does the throttle position sensor display a low voltage?

Code P0122 gets logged when the throttle position sensor “A” displays lower voltage than normal. Several OBD-II trouble codes also cover the performance of the throttle position sensor at the “A” position. They are:

What does GM p1400 cold start control system do?

GM defines a P1400 as Cold Start Emission Reduction Control System. That may sound like Greek to you, but there’s a method to their madness. A catalytic converter must warm up sufficiently to process excess hydrocarbons. One way to do that is to increase idle speed and retard timing during a cold start.
