1989 Mercedes Benz 420SEL (126 Chassis) Electro-Hydraulic Actuator Operation
The electro-hydraulic actuator is bolted to the side of the fuel distributor. It consists of a
plate valve fastened between two electromagnets.
By varying the electric current to the electro-hydraulic actuator and changing the
strength of the magnets, the plate valve can be moved. The varying position of the plate
valve controls the quantity of fuel allowed into the lower chamber of the fuel distributor,
causing the differential pressure to vary. The operating range is from -50 to +150mA.
Differential pressure will be from 0 bar to about 1.6 bar (24 PSI) less than system
pressure.

Concise 4×4 Driver Training Manual
This manual contains the ABSOLUTE MINIMUM knowledge deemed necessary to be known AND UNDERSTOOD by the average LROC member. However, this manual does not endeavour to explain the information presented here and therefore not everything presented here may be understood. This concise manual is complimented by the comprehensive manual where ALL this information is repeated but expanded with explanations where applicable. The LROC STRONGLY encourages its members to, at least once, read the entire comprehensive manual, just to understand how much more there is WORTH knowing. Written exam This “Concise Manual” also serves as the basis for the LROC’s written exam. Nothing outside of this manual will be asked in the exam. The exam will test knowledge only and is not intended to “be difficult”. It will not test the candidate’s understanding of the material. It is left to the member to ensure that a thorough understanding is reached where something is not understood – for your own benefit. Most of what is written in this manual regarding driving techniques are GUIDELINES due to off-roading situations being so variable (even though the wording may suggest otherwise). Therefore the most TYPICAL approach is presented here but with experience you WILL find that different/innovative approaches are sometimes called for.

2003 Saturn L300 V6-3.0L VIN R P2119-Throttle Closed Position Performance
The throttle actuator control (TAC) module contains a direct current actuator motor
controlled by the ECM used to move the throttle plate (in either direction) and two throttle
position sensors to determine throttle plate position. The throttle plate is held at a 7% rest
position to a mechanical stop by a constant force return spring. This spring will hold the
throttle plate to the stop when there is no current flowing to the actuator motor. There is
another return spring, which creates constant force on the throttle plate only when the
throttle plate is moved towards the full closed position. The ECM will monitor both the
actuator motor and TP sensors for circuit faults, as well as check to make sure both
springs can return the throttle to the 7% position no matter where the throttle plate
remains.

2005–2007 Toyota Corolla R & R Camshaft Timing Gear
Under certain conditions, customers may experience a M.I.L. “ON” condition with DTC P0011, P0012, or P0016 stored in the Engine Control Module/ECM (SAE term: Powertrain Control Module/PCM). In some cases, the cause of this DTC may be the VVT–i actuator. Use the procedures in this bulletin to verify the operation of the actuator and correct the condition.

The Conversion of a General Motors Cadillac SRX to Drive-By-Wire Status
For the past 25 years, by-wire systems have been used in the most advanced flying machines known to man. In the 1960s, McDonnell Douglas, now The Boeing Company produced the F-15 Strike Eagle, a magnificent fighter jet with fly-by-wire capability. Fly-by-wire is where each mechanism is controlled electronically. The mechanical linkages are removed and every movement is communicated through electric signals alone. The idea of fly-by-wire forever changed the concept that a mechanical linkage has to initiate movement (i.e. pitch, roll, and yaw) of a vehicle. The use of electronic motors to control movement has proven to be more responsive and a more efficient use of space and energy. The responsiveness of the fly-by-wire system is one of the heralding accomplishments that make the F-15 such an engineering accomplishment which can fly at 2.5 Mach speeds. Thus the by-wire control is now setting the stage for better, faster vehicles in the air and on land.
