Exhaust Pressure Sensor: Description and Operation

Exhaust Pressure Sensor

Exhaust Pressure (EP) Sensor:

The Exhaust Pressure (EP) sensor is a variable capacitor sensor that is supplied a 5-volt reference signal by the PCM and returns a linear analog voltage signal that indicates pressure. The EP sensor measures the pressure in the LH exhaust manifold. The EP sensor signal is no longer used. The PCM utilizes the MAF and other temperature inputs to calculate exhaust pressure.
