FUEL TRANSFER PUMP GROUP 1P0005 - Caterpillar

System Operation Description:Use this procedure if the diagnostic code in Table 1 is active.
Table 1
Diagnostic Codes Table    
Description    Conditions which Generate this Code    System Response    
261-11 Engine Timing Offset fault     The wiring to the sensors has the wrong polarity.     The code is logged.    
261-13 Engine Timing Calibration calibration required     A timing calibration is required for a new engine, replacing an Electronic Control Module (ECM) that fails to communicate or following work on the front gear train, the camshaft, or the crankshaft.     The code is logged.    If a 261-11 diagnostic code is active, verify that the wiring is installed correctly to the engine speed/timing sensors.The ECM has the ability to calibrate the mechanical differences between the Top Center (TC) of the flywheel and the TC of the timing gear on the camshaft. A magnetic transducer signals the TC of the flywheel to the ECM when a notch on a counterweight passes by the transducer. The engine speed/timing sensor signals the TC of the timing gear to the ECM. Any offset between the TC of the flywheel and the TC of the timing gear is stored into the memory of the ECM.Note: A timing calibration will not increase the available engine power.Table 2 lists the special tools that are required in order to perform this procedure.

( 1 ) This item is not required if the engine harness has a connector for timing calibration.Test Step 1. Timing Calibration
Install the Transducer Adapter
Remove the electrical power from the ECM.
Use the appropriate engine turning tool to put either the No. 1 piston or the No. 6 piston at top center. Refer to the Systems Operation/Testing and Adjusting.
Refer to Table 3. After the top center position has been located, rotate the crankshaft for the number of degrees that is applicable to your engine model. Be sure to rotate the crankshaft in the direction of rotation that is specified in the Table.
