What is a 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.
What do the p1131 p1151 p0174 codes mean?
All of these p1131 p1151 p0171 p0174 codes indicate a problem with a lean condition. This engine is known for vacuum leaks, so before you start throwing oxygen sensors at the problem, it pays to perform some diagnostics. Start by cleaning the MAF sensor.
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 are the possible causes of a p1151 Ford?
P1151 FORD Possible Causes 1 Faulty Upstream Oxygen Sensor Bank 2 2 Fuel pressure high or low 3 MAF sensor dirty/defective 4 Vacuum leak on engine 5 Leaking fuel injector or fuel pressure regulator 6 Faulty Powertrain Control Module (PCM)
What does P1401 mean on the dpfe sensor?
P1401 indicates a problem with the DPFE sensor, which is part of the EGR system. This code is relatively common on Ford engines… This code is relatively common on Ford engines, especially smaller four-cylinder makes.

What causes a ho2s reading of p1151?
Any other these would result in an incorrect HO2S reading and trouble code P1151. The next system to check is your fuel system. Leaking fuel injectors, low fuel, or too much fuel pressure could all result in this trouble code.
