P2011 - FLOW-RATE VALVE

1.9 JTD 16v, 2.4 JTD 20v

The diagnostic equipment signals: Error P2011 (flow valve).

This error is detected if there is a break in the circuit connected to Pin 19 and 6 of the junction unit for at least 0.22 secs.

1	Check for break in electrical power supply circuit	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Turn the ignition key to the OFF position. Disconnect the cable loom connector from the flow modifying solenoid valve. See L064 FLOW MODIFYING SOLENOID VALVE Turn the ignition key to the ON position. Measure the voltage between Pin 1 (wiring side) of the solenoid valve and earth, checking that it is more than 11 V See L064 FLOW MODIFYING SOLENOID VALVE	Move on to Step 2	Voltage lower than 11 V	Move on to Step 6
2	Check insulation to +Vbatt of signal electrical circuit	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Turn the ignition key to the OFF position. Disconnect the cable loom connector from Connector B of the engine management control unit. See M010 ENGINE MANAGEMENT ECU Turn the ignition key to the ON position. Measure the voltage between Pin 2 (wiring side) of the solenoid valve and earth, checking that it is less than 0.3 V See L064 FLOW MODIFYING SOLENOID VALVE	Move on to Step 3	Short circuit to +Vbatt between flow valve and engine management control unit	Restore correct electrical connections. Replace the wiring if necessary
3	Check insulation to earth of signal electrical circuit	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Turn the ignition key to the OFF position. Measure the resistance between Pin 2 (wiring side) of the solenoid valve and earth, checking that it is more than 500 kOhm See L064 FLOW MODIFYING SOLENOID VALVE	Move on to Step 4	Short circuit to earth between flow valve and engine management control unit	Restore correct electrical connections. Replace the wiring if necessary
4	Check on continuity of signal electrical circuit	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Measure the resistance between Pin 2 (wiring side) of the solenoid valve and Pin 6 (wiring side) of Connector B of the junction unit, checking that it is less than 5 Ohm See L064 FLOW MODIFYING SOLENOID VALVE See M010 ENGINE MANAGEMENT ECU	Move on to Step 5	Open circuit between flow valve and engine management control unit	Restore correct electrical connections. Replace the wiring if necessary
5	Replacement of flow valve	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Replace the flow valve and check that the problem disappears Op. 1072B60 THROTTLE SHAFT CONTROL VALVE FOR INLET PORTS R R	End of diagnosis	The fault persists	Restore the original solenoid valve and replace the engine management control unit Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - .R
6	Check for break in electrical power supply circuit	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Turn the ignition key to the OFF position. Disconnect the cable loom connector from Connector A of the engine management control unit. See M010 ENGINE MANAGEMENT ECU Extract the relay T9 from the socket in the engine compartment junction unit. See B001 IGNITION SWITCH NOT WORKING Connect a bridge with a fuse to Pins 87 and 30 of the socket for relay T9. Measure the voltage between Pin 72 Connector A (wiring side) of the control unit and earth, checking that it is more than 11 V See M010 ENGINE MANAGEMENT ECU	Move on to Step 7	Open circuit between engine compartment junction unit and engine management control unit	Restore correct electrical connections. Replace the wiring if necessary
7	Restore electrical connections	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	If the wiring between the control unit and the solenoid valve is faulty, restore the correct connections See M010 ENGINE MANAGEMENT ECU See L064 FLOW MODIFYING SOLENOID VALVE	End of diagnosis	The wiring is not faulty	Replace the engine management control unit Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - .R
