NOTESPriority when dealing with a number of faults:
Deal firstly with fault DF084 Actuator relay control circuit or DF046 Battery voltage
if they are present or stored.
Special note:
–level 1 fault warning light illuminated.
– throttle valve defect mode types 1, 2 or 4.
Check the cleanliness and condition of the throttle valve connections.
Check the cleanliness and condition of the pedal potentiometer connections.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Repair if necessary.
Sensor feed No. 1 is reserved for the following components:
– inlet manifold pressure sensor
– turbocharger pressure sensor (F4RT 774 and 776 only)
– pedal potentiometer gang 2,
– coolant pressure sensor,
– Cruise control/Speed limiter buttons,
– upstream and downstream O
2 sensors.
To locate any internal fault on one of the sensors with a 5V supply (short circuit), disconnect each of the sensors
on the list above in turn, checking after each disconnection whether the fault changes status from present to stored.
If the faulty sensor is located, check its connections and that it is in order.
Replace the faulty sensor if necessary.
AFTER REPAIRDeal with any faults declared by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

(K4M 766/812 and 813, F4R 770 and 771)
track 5 of the motorised throttle valve
(K4J 740, K4M 788 LPG, F4RT 774 and 776)
Repair if necessary.
If the fault is still present, contact the Techline.
