The supply voltage is 5.0 ± 0.16 VDC. Refer to Specifications Manual. Engine oil pressure sensor. So its still within specs. 3) all relays shown not energized. Check for logged diagnostic codes for the injector solenoids. Designed to keep the turb right behind this is a weather pak connector with 2 wires. Blow Off Valves; Con Rods; Fuel Injectors; Fuel Pressure adapters; Fuel pressure … Compatibility Guaranteed! We had a 345 B hoe with a 3176 that had a little sensor for manifold pressure on the air intake manifold that would go bad and have the same problems your saying, low power, poor recovery, etc. Does it have 1 of them manifold sensors I described? I have a boost gauge/pyrometer combo on my Dodge/Cummins which reads 0-40 lbs boost and the pyromoter reads 0-2,000 degrees. When the ECM senses a higher boost pressure, the ECM increases the FRC Limit (Fuel). Engine had 550k at the time. Repair the lines and/or replace the lines. The FRC Limit (Fuel) is based on the boost pressure. Share this post. Will Work on 1993 and newer engines. Cat® C12 Diesel Marine Propulsion Engines, with ratings of 340-490 bhp (254-366 bkW) at 1800-2300 rpm, meet IMO II emission standards with the exception of the 497 mhp (490 bhp) rating at 2300 rpm which meets IMO I emissions standards.
