KIT-SEAL 5098556 - Caterpillar

air pressure that is in the air induction system is monitored by the right turbocharger compressor inlet pressure sensor and by the left turbocharger compressor inlet pressure sensor. The sensors are located in each air inlet tube. The sensors are used in conjunction with the atmospheric pressure sensor to determine if the engine air filter is plugged. The sensors indicate if the left turbocharger compressor inlet or the right turbocharger compressor inlet has a restriction. The Electric Control Module (ECM) provides the sensor with a 5.0 0.2 VDC supply voltage. The output of the turbocharger inlet pressure sensor is a DC voltage signal. The signal has a range of 0.2 to 4.8 volts.
