Conditions for applying the fault finding procedure to stored faults:
The fault is considered present if:
– the engine speed varies,
– the engine air temperature is between 5°C and 105°C.

Check the cleanliness, condition and fitting of the throttle valve.
Repair if necessary.
If the fault is still present, manually check that the throttle valve rotates correctly.
Repair if necessary.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.

If the fault is still present, manipulate the harness to detect a change in status (present ↔ stored).
Look for possible damage to the wiring harness, check the condition and the connection of the connectors of the
injection computer and motorised throttle valve.
Repair if necessary.
If the fault is still present, disconnect the battery and the injection computer.
Check the insulation, continuity and the absence of interference resistance of the following connections:
Injection computer, connector B, track M3 track 3 of the motorised throttle
(K4M 766/812 and 813, F4R 770 and 771)

track 6 of the motorised throttle valve
(K4J 740, K4M 788 LPG, F4RT 774 and 776)
If the fault is still present, measure the resistance of the throttle between
– tracks3 and 5 for (K4M 766/812 and 813, F4R 770 and 771),
– tracks3 and 4 for (K4J 740, K4M 788 LPG, F4RT 774 and 776).
Replace the throttle valve if the resistance is not
–2.2Ω ±0.2Ω at 23°C for (K4M 766/812 and 813, F4R 770 and 771),
–1.6Ω ±0.2Ω at 23°C for (K4J 740, K4M 788 LPG, F4RT 774 and 776).
If the fault is still present, disconnect the battery and the injection computer.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.
