633 SPN Fault Code

Name:

Engine Fuel Actuator 1 Control Command

Description:

The control command to fuel actuator 1, normalized to percent, where 0% represents fully closed and 100% represents fully open. In applications where the fuel actuator controls to differential pressure, 0% represents minimum differential pressure and 100% represents maximum differential pressure. Typically, this fuel actuator is used to regulate low pressure natural gas flow rate, mixing into the air flow, which together then come into the engine. Using the standard convention for determining the position. If only 2 actuators are present, then left/front is #1 (SPN 633) and right/rear is #2 (SPN 1244). If more than two actuators are present, then left/front is #1 (SPN 633), left/rear is #2 (SPN 1244), right/front is #3 (SPN 7593) and right/rear is #4 (SPN 7594).The values of FB00h � FB64h are sent to initiate the self calibration of the fuel actuator. The LSB specifies the % to calibrate to with a resolution of 1%/bit (eg, FB32h is sent to calibrate the actuator to 50%). In the case of

633 spn fault code name is Engine Fuel Actuator 1 Control Command. If you don't take the time to look into 633 spn fault when it arises, it can add up quickly. One small issue like 633 can cause a larger component to become damaged without taking the time to investigate. If you suspect your truck is suffering from one of these issues, look into replacing those small components to save money down the road.

Note: The name and description of 633 code represents text descriptions for faults supported by another coding system and does not necessarily comply with SAE J1939. For a specific engine manufacturer's explanation for codes, please consult the engine's technical manual. See also other spn codes.
