NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present following a road test or after attempting to start the
engine several times.
Special notes:
If the fault is present:
– cruise control is deactivated,
– the engine speed is limited,

To locate a faulty sensor and/or connection, disconnect one of these sensors then check whether the fault
becomes stored.
If the fault is still present, start the operation again with the other sensor.
(wait a few seconds between each disconnection to allow the computer to perform the measurement).
If the fault is stored after a disconnection, replace the faulty sensor or repair its connection.
Clear the faults created by the multiple disconnections.
If the fault is still present when both these sensors have been disconnected:
1. Check the insulation from earth of the following connections:
Injection computer brown 48-track connector B, track K2 Track 3 of the turbocharger pressure
