What is a P0470 code?
What is a P0470 code?
P0470 is a diagnostic trouble code (DTC) for “Exhaust Pressure Sensor Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What does the p0470 Ford engine pressure sensor mean?
P0470 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’s the difference between p0470 and P0 471?
This can be an electrical circuit fault or it can be mechanical. 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.
How much does it cost to repair a p0470 Ford?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. What does this mean? The cost of diagnosing the P0470 FORD code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
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.
