Where is the Ford TFI ignition module located?

Ford used the TFI ignition module (thick film ignition) on vehicles from 1983 through the mid-1990s only. The vehicles that used this module had a conventional hall-effect distributor with a separate coil. The TFI module was located on a flat area on the base of the distributor.

What does the TFI module on a Ford EEC do?

The TFI module is also known as the Ignition Control Module (ICM) which reports engine position and rpm to the PCM. The PCM then determines the proper spark timing and advance, and returns a reference signal to tell the TFI module to switch the coil, thereby by creating a spark.

How does the TFI control the ignition coil?

The falling edge of the signal is generated to control the timing for turning the ignition coil on (the TFI no longer controls this function as during the push start mode). During the CCD mode, the coil on time, or dwell, is entirely controlled by the PCM through the SPOUT signal.

What are the computer codes for Ford TFI-IV?

If your TFI is failing from heat, it can give off computer codes 14 (PIP) and 18 (SPOUT). The TFI-IV distributor ignition system consists of the following components: The distributor ignition system designed by Ford has two distinct configurations.
