· Coolant temperature less than -
37 °C / - 34.6 °F
(short circuit to voltage or
circuit interruption)
· Condition must be fulfilled for at least
1 s
Replacement values:
· With ignition ON and trouble codes 69 and
71 not recognized, the intake air temperature is taken as the starting value
· With ignition ON and trouble code 69 or
71 recognized, 10 °C / 50 °F is taken as the starting
value
· If a plausible measured value has already
been produced for the coolant temperature, it is used as the starting value
· The starting value' is increased
by 1 °C / 1.8 °F every 146 cycles (1 cycle
720 °CA) to a maximum value of 99 °C / 210 °F
This value is used for the
remaining engine operation.
Effects:
· All adaptation except knock
adaptation, throttle valve adaptation and idle speed adjuster adaptation are
blocked
