1Stop screw
2Toothed segment

4Throttle flap return spring
5Joint shaft
6Electric motor with pinion
NOTICE: The throttle control unit must not be repaired or adjusted. The stop of the throttle valve must on no account be adjusted.
The APP sensor provides the PCM with information about the driver's request for acceleration.
The throttle control unit receives a corresponding input signal from the PCM. An electric motor then moves the throttle valve shaft by means of a set of gears. The throttle valve position is constantly detected by the TP sensor and information about the position is processed and monitored by the PCM. With the throttle valve position kept constant, the ignition angle and the injected fuel quantity are then varied to meet the torque demands. Depending on the operating state of the engine, a change in the position of the throttle flap may not be necessary when the APP sensor changes.
If a fault develops in the throttle control unit, a standby function is executed. This standby function allows a slight opening of the throttle flap, so that enough air passes through to allow limited engine operation. For this purpose, there is a throttle flap adjustment screw on the throttle housing. The return spring closes the throttle flap until the stop of the toothed segment touches the stop screw. In this way a defined throttle flap gap is formed for limp home mode.
The stop screw has a spring loaded pin, which holds the throttle flap open for limp home mode. In normal operating mode, this spring loaded pin is pushed in by the force of the electric motor when the throttle flap must be closed past the limp home position (e.g. for idle speed control or overrun shutoff).




Engine Oil Pressure (EOP) switch



This connects earth to the EOP depending on the PCM. This signal is needed to actuate the {Acronym.VVT} solenoid.
This information is also conveyed via the CAN databus to the instrument cluster, where the EOP warning light is turned on or off accordingly.

Diagnosis and Testing Refer to Wiring Diagrams Section 307-01, for schematic and connector information. General Equipment  diagnostic equipment Inspection and Verification Verify the customer concern. Visually inspect for obvious signs of mechanical or electrical damage. Visual Inspection Mechanical Electrical Fluid level too high/low Poor condition of fluid Fluid leak Damaged shift mechanism/linkages Damaged automatic transmission/ transaxle casing Fuse(s) Relay(s) Wiring harness Electrical connector(s) Selector lever module Transmission control module (TCM) If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step If the cause is not visually evident, verify the symptom and refer to the Ford diagnostic equipment to diagnose the system.

Contrôle et vérification Note : Le module électronique générique (GEM) fait partie du boîtier électrique central (CJB). Note : Si le module GEM est remplacé, le module neuf doit être configuré après la pose. A cet effet, les données spécifiques au véhicule sont extraites du module à remplacer à l'aide de l'équipement de diagnostic et sont transférées dans le module neuf. Note : Avant d'extraire les données spécifiques au véhicule, s'assurer que toutes les connexions électriques du véhicule sont de nouveaux raccordées, de sorte que le module et l'outil de diagnostic puissent communiquer correct
