199002154 - P0045 Turbo actuator command (90 CV)

The error is recognized by comparing the control with the feedback (microcontrol diagnosis).The test is carried out if the battery voltage and the main relay are okay and the duty cycle is less than 99% (with detail CA - open circuit or CC GND - short circuit to earth) and more than 1% (with detail CC VBAT - battery voltage short circuit).

		Test results
0	PRELIMINARY CHECKS	All OK	Problems encountered	Operation
	Check, in the engine compartment junction unit, that relay T7 (the first from the top in the bottom left row) is working properly and that fuse F27 (the fourth from the top in the left row) have not blown	Move on to Step 1	Relay T7 is broken	Replace the relay
			Fuse F27 has blown	Replace the fuse, then search for the cause of the problem and eliminate it
1	ELECTRICAL CIRCUIT CHECK	All OK	Problems encountered	Operation
	Check the continuity and the insulation of the turbo actuator supply circuit    See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT	Move on to Step 2	Connections not correct	Restore or, if necessary, replace the wiring
2	Turbo actuator replacement	All OK	Problems encountered	Operation
	Replace the turbo actuator    Op. 1064B42 SOLENOID CONTROLLING TURBOCHARGER VANE POSITION ACTUATOR - R.R and check the fault has disappeared	End of diagnosis	The fault persists	Contact technical service for further information on the problem
