FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL
If one of the two APP sensors fails, then only a
proportion of the engine's power will be available
when accelerating. Top speed can nevertheless
be achieved.
If both of the APP sensors fail, the engine is
regulated to a defined speed following a plausibility
check after the BPP (brake pedal position) switch
and brake light switch have been actuated once.
The vehicle can then only be accelerated to a
defined speed.
In either case, a fault is saved in the error memory
of the PCM.

CAUTION: The throttle control unit must
not be repaired or adjusted. The stop of
the throttle valve must on no account be
adjusted.
After disconnecting the battery or replacing the
throttle control unit or the PCM, initialization is
necessary. • engine off
• Accelerator pedal not pressed
• Battery voltage 11 ... 14 V
• Ignition key in ON position
• Wait approximately 30 seconds until initialization
is complete.
Engine Coolant Temperature (ECT)
sensor
E94804
The ECT (engine coolant temperature) sensor is
designed as an NTC (negative temperature
coefficient) resistor.
If the signal from the ECT sensor fails, the cooling
fan is on all the time and the A/C (air conditioning)
is turned off. When the ignition is switched on, the
value from the IAT (intake air temperature) sensor
is read. When the engine is running, the
temperature is calculated using a temperature map
stored in the PCM according to how long the
engine has been running. This substitute value is
then used as the basis for calculating the injected
fuel quantity and the ignition timing.
