P0470 Exhaust Pressure Sensor Malfunction
P0470 OBD Code Description:
OBD2 Code P0470 Definition:
The exhaust back pressure (EBP) sensor is a variable capacitance sensor that, when supplied with a 5-volt reference signal from the Powertrain Control Module (PCM), produces a linear analog voltage signal that indicates pressure. The EBP sensor’s primary function is to measure exhaust back pressure so that the PCM can control the exhaust back pressure regulator (EPR) when needed.
Symptoms
Possible sumptoms of P0470
– Engine Light ON (or Service Engine Soon Warning Light)
Possible Causes
Possible causes of P0470
– Exhaust Back Pressure Sensor The Error code is generally activated on detection of the following conditions: An EBP signal that is detected out of range (high or low) by the PCM will cause the engine to ignore the EBP signal and disable exhaust back pressure operation.
Possible Solutions
Replacing the exhaust back pressure usually takes care of the problem
