P0192 Fuel Pressure Sensor Low Theory of Operation The Powertrain Control Module (PCM) provides the Fuel Rail Pressure Sensor with a 5-Volt supply and sensor ground, and receives a signal voltage back from the Fuel Rail Pressure Sensor. This sensor signal voltage changes based on the pressure in the fuel rail. The PCM will light the MIL lamp immediately after the diagnostic runs and fails. During this time the customer may experience a power and or speed derate. The PCM will turn off the MIL light after the diagnostic runs and passes in four consecutive drive cycles. When Monitore

P0128-THERMOSTAT RATIONALITY Theory of Operation The thermostat rationality diagnostic runs during a drive cycle that starts with the coolant temperature below 140°F. This diagnostic looks at the how cold the system is at start up, what the inlet air temperature is, and the amount of fuel burned during that drive cycle. The PCM estimates what the coolant temperature should be. If the coolant temperature is not above a calibrated threshold, the rationality fails. The PCM assumes that the thermostat is stuck open. When Monitored: While the engine is running. Set Condition:

P0191 - Fuel Pressure Sensor Circuit Performance Theory of Operation This DTC is mapped to an idle diagnostic, and runs only at idle. The key-on error monitors fuel pressure voltage at key on after an eight hour cold soak. The Powertrain Control Module (PCM) varies fuel pressure and monitors the final fueling and engine speed to determine if the rate of change of fueling with respect to rate of change of pressure is with in the normal operation limits of the pressure sensor. The engine must be at operating temperature and must not be in an active aftertreatment regeneration mod

P0169 - Water In Fuel Detected For Too Long Theory of Operation There are two Water-In-Fuel (WIF) sensors attached to the two fuel filters. WIF 1 is attached to the fuel filter mounted on the engine. WIF 2 is attached to a 2nd fuel filter that can now be found mounted to the chassis. The Powertrain Control Module (PCM) provides a 5-Volt reference signal to each WIF sensor. When the water collected in the respective fuel filter covers the sensor probes, the sensor then pulls the 5-Volt reference voltage low indicating high water accumulation in that fuel filter. When Monitored:

LED Lighting Parts List LED marker light LED Taillight Heavy duty LED flasher As for installing it just simple change of parts. The flasher is found in your driver side of the dash. If the flasher been there a while then it might be difficult to remove. Just take your time and work the flasher it will come out. Pull the stock flasher out and plug in the new flasher. The replacement flasher can is slightly larger for the 12V dash. It will barely fit. Make sure to get the electronic flasher can. As for the taillights you need a T25 sc

Replacing injectors on a CR engine isn't much different that changing injectors on a 24V. There is a few differences but the process is the same. First you need to make sure the fuel rail area is clean. Best to take a power washer and blow all the crud and dirt off the fuel rail side of the head. Remove the intake horn and grid heater. Pack a few rags in the intake to prevent anything from falling in by chance. Now you need to remove the fuel rail and all the connecting lines to the head. It will come out in one piece with the rail and the lines attached. B

P0118 - Engine Coolant Temperature Sensor 1 Circuit High Theory of Operation The Engine Coolant Temperature Sensor (ECT) is located near the thermostat housing and is used to measure the engine coolant temperature. The Engine Coolant Temperature Sensor receives 5-Volts and a sensor ground from the PCM. The PCM monitors the change in voltage to determine the coolant temperature.
