NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is considered present when the engine is running.
Priorities when dealing with a number of faults:
– Deal with all the other faults before fault DF859
Special notes:
This fault is activated when the injectors have not been reset for 1800 miles
(3000 km).
Leave the vehicle to run at idle speed until the engine is warm.
When the engine is warm (PR064 COOLANT TEMPERATURE above 77°C), carry out the following test drive:
– Drive at a speed of up to 30 mph (50 km/h) and change into 5th gear.
– Stay in this gear and perform 8 accelerations from 30 mph (50 Km/h) to 54 mph (90 Km/h).
– At the end of driving: without switching off the ignition, allow the vehicle to run at idle speed for at least
10 minutes.
– Switch off the ignition, and wait 30 seconds.
– switch on the ignition, check that the fault is stored and clear the fault.
