6646-15 E222 (1) Troubleshooting, "Fuel Pressure Is Low (Gas Supply)" The In Cylinder Pressure Sensor (ICPS) system provides cylinder health feedback information to the ICPS Electronic Control Module (ECM). The ICPS ECM will take the appropriate action based on the measured level of cylinder pressure. Gas Blending substitution levels will be reduced to lower cylinder pressure for Level 2 events. Level 3 events will disable gas blending for all cylinders. The ICPS replaced the block-mounted detonation sensors that gas engines previously used.Changes in engine operating conditions and various performance factors will contribute or directly cause pre-ignition and detonation to occur. The engine ECM and sensors monitor a range of pressure and temperatures which can affect engine performance and combustion effectivity.Probable Causes
