2.DEF NOTES
Priorities when dealing with a number of faults:
Firstly, apply the interpretation of the DF199 Turbocharging
pressure sensor, CC.1 fault, if it is present or stored.
Check the connections of the turbocharging pressure relief solenoid valve.
Check the engine management computer connections.
Repair if necessary.
Check the resistance of the turbocharging pressure relief solenoid valve between tracks 1 and 2:
Replace the solenoid valve if its resistance is not:
15.4 Ω ± 0.7 at + 20˚C for a Pierburg solenoid valve.
16.5 Ω ± 1.6 at + 25˚C for a Bitron solenoid valve.
Check the continuity and absence of interference resistance on the connection between:
Engine computer, connector B track L2 track 1 of the turbocharging pressure relief
solenoid valve connector
Check for the + 12 V after relay feed on track 2 of the turbocharging pressure relief connector.
● Make sure the turbocharging pressure relief solenoid valve is not jammed open:
– With the engine switched off, disconnect the input and output hoses of the solenoid valve.
With a Pierburg solenoid valve:
– Connect a vacuum pump to the inlet union and apply a vacuum.
– If the vacuum pressure is not maintained: replace the solenoid valve.
With a Bitron solenoid valve:
– Fit a plug to the solenoid valve outlet union.
– Connect a vacuum pump to the inlet union and apply a vacuum.
– If the vacuum is maintained: replace the solenoid valve.
● Check that the control rod of the turbocharger is not jammed:
– Apply test 6 for a turbocharger with fixed geometry.
– Apply test 7 for a turbocharger with variable geometry.
