What does the p0471 Ford exhaust pressure sensor do?
What does the p0471 Ford exhaust pressure sensor do?
P0471 FORD Meaning The Exhaust Back Pressure (EBP) sensor is a variable capacitance sensor that, when supplied with a 5-volt reference signal from the Engine Control Module (ECM), produces a linear analog voltage signal that indicates pressure.
What causes an exhaust pressure sensor to go off?
An Exhaust Back Pressure (EBP) signal that is detected out of range (high or low) by the Engine Control Module (ECM) will cause the engine to ignore the EBP signal and disable exhaust back pressure operation.
What does the EBP sensor on a Ford do?
The EBP sensor’s primary function is to measure exhaust back pressure so that the ECM can control the exhaust back pressure regulator (EPR) when needed. Need more information on how to fix the P0471 FORD code?
How to test the exhaust backpressure ( EBP ) sensor?
Using scan tool, select EBP PID from PID/DATA monitor menu. If EBP reading is less than 18.5 psi, clear DTCs. Repeat KOEO ON-DEMAND SELF-TEST. If DTC is still present, replace PCM. If EBP reading is 18.5 psi or more, go to next step. 2) Check Signal Ground Circuit Turn ignition off. Disconnect EBP sensor connector.
What is the DTC code for exhaust pressure sensor?
Code P0471 may also be present at the same time as the P0470. The only difference between these 2 codes is how long the problem lasts and the type of electrical / mechanical problem that the sensor / circuit / engine controller is having.
What are the dangers of an exhaust pressure sensor?
