DESCRIPTION AND OPERATION
Acceleration Control
I .3L Duratec 8V
Item Description
I 1 I Accelerator cable
1 2 IThrottle body I
The throttle is cable operated on the 1.3L Duratec
8V engine.
There are two different throttle bodies, depending
on the power of the variant.
Because the throttle flap opening angle is different,
the way in which the cable is controlled at the
throttle flap varies slightly between the two different
variants.
I .4L/1.6L Duratec 16V
The 1.4Ll1.6L Duratec 16V engines have an
electronically controlled throttle flap control unit.
For information on the electronically controlled
throttle flap control unit, please refer to Section
303-1 4.

DIAGNOSIS AND TESTING
PCM to the electronic throttle body including
the electrical connectors in area "B" (see
system overview).
- There is an obstruction inside the throttle
body bore. Remove the air cleaner outlet pipe
and check for obstructions.
- There is an obstruction inside the electronic
throttle body. Remove the air cleaner outlet
pipe and check that the plate moves freely
against the springs and returns to a slightly
open position. If it does not, install a new
electronic throttle body.
P2176 - Throttle plate adaptation error
- When the ignition is turned off, the throttle
body carries out an adaptation cycle and
spring check. This can be audible after a
short delay (up to 30 seconds) following the ignition key being turned to position
0 and
can be visually observed with the air cleaner
outlet pipe removed. The throttle plate is
moved through a series of positions to check
the TP sensor value and relearn the
electronic throttle body characteristics. If a
concern is detected during this test,
P2176
DTC will be set. If there are already any of
I the other DTCs, the adaptation test could
potentially fail. Therefore the other DTCs
should be resolved first
(e.g. low battery
voltage) and a retest can be carried out by
clearing the DTCs and keying on and off
again. Check the whole area "B" (see system
overview) for any concerns and if no concern
is found, install a new electronic throttle body.
P2100 - H bridge error
- A fault has been detected on the circuit
connecting the electronic throttle body motor
and the PCM. Check for any other
non-electronic accelerator control related
DTCs and rectify them first. Check area "B"
(see system overview) and if no failure is
found, install a new PCM.
PCM Related Codes
The PCM continuously monitors all the sensors. It
also checks that the monitor is functioning as
expected. If there is a fault with the monitor, the
following DTCs will be set.
P2107 - Processor monitoring on the main
controller fault.
P2108 -Analogue to digital converter
- Inferred intake mass air flow lower than
expected
- Engine speed monitor ratio error
- Pedal ratio monitor error
- TP sensor ratio monitor error
- Fault in torque generation
- Fault present in engine speed limitation
Multiple sensor faults can make the PCM assume
that there is a monitor fault. If other DTCs exist,
rectify these first. These DTCs indicate a failure in
area
"A or "B" and they are also related to the
manifold absolute pressure and temperature
(MAPT) sensor and the crankshaft position (CKP)
sensor. If no other failures are found, install a new
PCM.
Indirect Codes
There are two brake pedal switches located under
the brake pedal. Check that both of these are
connected and functioning correctly. A brake pedal
switch concern will only cause the "EAC FAIL"
message to be displayed, it will not lead to a limited
performance mode. Follow WDS instructions.
PO571 - Brake switch error
If the voltage to the accelerator pedal and the
electronic throttle body cannot be regulated
correctly, the components may not operate as
expected. Therefore it is important to detect if there
is a concern in the supply voltage
PO641 - Sensor voltage supply circuit I noisy
signal
PO642 - Sensor voltage supply circuit 1 short
to ground or open circuit
PO643 - Sensor voltage supply circuit 1 short
to battery
PO651 - Sensor voltage supply circuit 2 noisy
signal
PO652 - Sensor voltage supply circuit 2 short
to ground or open circuit
