If failure is present only when engine is running, check with the contact set on, the valve
position parameter coherence for: release acceleration pedal and maximum presse d pedal.
Easy push the accele ration pedal (from release d pedal t ill maximum acceleration) and check that
valve position is regularly increasing.
If a.m. are not observed, the inf ormation is not conform. In such case , treat the diagnostic of this

th e measured resistance with the recommended ones.
R eplace the pressure sensor if necessa ry.
C onnect the 90 ways terminal box instead of the injection computer then check the insulation,
continuity and absence of the parasite resistance on lines: Pin 16 injection computer > pin B atmospheric pressure sensor

If the problem is not solved, use the recommended me thod for DF345 failure.
RE CO MMENDATIONS
If failure “DF345”: Supply 5 volts potentiometers or sensors” is prese nt or
memorize d, this must be treated as most important.
C onditions for diagnostic application to memorized failure:
Set t he contact off and wait until the communication CLIP tester-computer
is lost. Set the contact on again, and then enter in dialog with the computer.
If it is necessa ry, start the engine and accelerate to over 608 rot/min for a
period of minimum 10 seconds.
