Ford TFI-IV System Details And Diagrams

Image
Ford Engine TFI-IV System GENERAL INFORMATION See Figures 1 and 2 Fig. Fig. 1: TFI schematic Fig. Fig. 2: Exploded view of the TFI components The Thick Film Integrated (TFI-IV) ignition system uses a camshaft driven distributor with no centrifugal or vacuum advance. The distributor has a diecast base, incorporating a Hall effect stator assembly. The TFI-IV system module is mounted on the distributor base, it has 6 pins and uses an E-Core ignition coil, named after the shape of the laminations making up the core. The TFI-IV module supplies voltage to the Profile Ignition Pick-up (PIP) sensor, which sends the crankshaft position information to the TFI-IV module. The TFI-IV module then sends this information to the EEC-IV module, which determines the spark timing and sends an electronic signal to the TFI-IV ignition module to turn off the coil and produce a spark to fire the spark plug. The operation of the universal distributor is accomplished through the H...

How To Service Automatic Transmission

Image
Automatic Transmission Service Step by step service guide on how to service an automatic transmission, this article pertains to most vehicles but was performed on a 2002-2007 Saturn Vue. Difficulty Scale: 3 of 10 Tools and Supplies Needed Transmission fluid Transmission filter service kit (if equipped) Socket set Fluid funnel Protective eyewear and gloves Helpful Information Changing the fluid in the automatic transmission in your vehicle promotes proper operation and helps the transmission last longer without failure. All car manufacturers have different service intervals for their particular transmission. In a typical transmission service, the fluid is completely flushed (including the torque converter), a filter is changed, the transmission pan is cleaned and a new pan gasket installed. Common Problems Premature transmission failure due to lack of maintenance, low fluid, dirty filter. Manual transmission: premature clutch failure due to abusive drivi...

how to replace Throttle position sensor on 2000 ford expedition

Ford TPS Sensor Replacement Throttle Position Sensor The Throttle Position (TP) sensor is a potentiometer that provides a signal to the PCM that is directly proportional to the throttle plate position. The TP sensor is mounted on the side of the throttle body and is connected to the throttle plate shaft. The TP sensor monitors throttle plate movement and position, and transmits an appropriate electrical signal to the PCM. These signals are used by the PCM to adjust the air/fuel mixture, spark timing and EGR operation according to engine load at idle, part throttle, or full throttle. The TP sensor is not adjustable. The TP sensor receives a 5 volt reference signal and a ground circuit from the PCM. A return signal circuit is connected to a wiper that runs on a resistor internally on the sensor. The further the throttle is opened, the wiper moves along the resistor, at wide open throttle, the wiper essentially creates a loop between the reference signal and the signal return ret...
