· On engine start, the
voltage level change for the camshaft signal does not occur between the 1st
and the 6th crankshaft teeth
· If trouble code 92 and
engine speed higher than 8000 rpm were recognised, trouble code 19
(crankshaft fault) is also stored
(short circuit of signal lead to oscillator lead)
(short circuit to ground or circuit interruption)
· Conditions must be
fulfilled for at least 3.5 s
Replacement
values:
Emergency
operation:
· During the engine warm-up
phase, the engine speed is limited to 4512 rpm, the ignition is retarded
by 12 °CA and knock control is blocked. In operation, the engine runs
without limitation
Note:
An abrupt
failure of the camshaft signal in operation (without loose contact) can only
be recognised the next time the engine is started.
Emergency
operation remains active until the next "ignition OFF".
