When did Ford start using the TFI ignition module?

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.

When do the TFI codes erase on a Ford Bronco?

Eventually there will be a single quick sweep of the needle; this is the throttle goose test. When this happens, the throttle must be depressed (a minimum) of 25%. The codes will be soon to follow, as per the previous test. Codes automatically erase after 60-100 starts.

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.

Where is the fuel injection code on a Bronco?

40 – Series Fuel/Air Injection Codes On Vehicles With Dual Oxygen Sensors Refer To The Right Or Rear Sensor Except: 1984-1988 3.8L Engines: Left Sensor (M) System was lean for 15 seconds or more (no HO2S switching) – Fuel control (M) System was rich for 15 seconds or more (no HO2S switching) – Fuel control

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.

Why is my spark spout not working on my Ford TFI?

The yellow spark output signal wire is without a section of insulation. This section happens to run through a shield ground that provided a convenient ground source for the SPOUT signal. Just the right bump in the road or vibration from the engine would provide a path of lesser resistance for the SPOUT signal, killing the coil trigger.

What causes a Ford EEC IV TFI to stall?

What’s the problem with the throttle on a Ford truck?

Electronic Throttle Body Malfunction Electronic throttle bodies have been a long-reported issue in Ford vehicles. In today’s Ford F-Series trucks, the electronic throttle body (ETB) is data-controlled. The ETB transmits sensory data to the throttle valve, which controls the quantity of air that passes to the engine.

What is the PIP signal on a Ford ignition module?

The Profile Ignition Pickup sensor signal (more commonly called the PIP signal) is critical for the ignition control module to start sparking the ignition coil at START UP and at all engine speeds. The Profile Ignition Pickup sensor is a Hall Effect type crankshaft position sensor and produces a digital…

When did Ford start using thick film ignition?

Thick Film Ignition (TFI) modules were used on Ford vehicles with distributors from the early 1980s to the mid-1990s. It was used on a number of Ford’s engines, the EFI 5.0 engines in particular. The TFI module is a gray box fitted to the side of the distributor. It is about one inch wide, and about four inches long.

Where does the timing signal go on a TFI ignition switch?

STRT: Battery voltage input with ignition switch in start (cranking) position. SPOUT: The timing control signal from your controller to the module goes on this wire. PIP: This signal provides the crankshaft position. The other three pins on the side of the module are for the distributor’s sensor. These pins are:

Why does my car stall after a few miles?

When a bad module is responsible for an intermittent stalling problem, the engine will usually cold start just fine and run OK for short distances, but stalls after driving more than a few miles or when driving at highway speeds (especially during hot weather). It’s as if somebody suddenly turned off the ignition.

Can a Ford Truck start with a misfire condition?

Whether your Ford or Mercury car or truck CRANKS but DOES NOT START or runs with a MISFIRE Condition, this article is for you.

What causes a Ford ignition module to fail?

However, this does not always work properly. There have been many problems with this system, stemming from heat saturation, cracking and a myriad of problems after a period of service. The modules will fail once they have absorbed too much heat or for case problems.

What causes a Ford Taurus engine to stall?

If your Ford Taurus’s engine timing is off, it’s going to stall out, misfire, and altogether not run properly. Here are some of the more common causes of an engine timing problem: VVT Problem– Many modern engines are equipped with Variable Valve Timing.

What to do if your Ford Taurus won’t start?

If you have an intermittent problem where your Ford Taurus won’t start – no crank, no noise, absolutely nothing – then you may have the same problem I had. My car came with a extra security system where you have to push a button on a remote before starting the car.

When did my Ford Taurus have the transmission replaced?

I have a 1994 Ford Taurus that had the engine replaced as well as the transmission about 6 months after we purchased it 3 years ago. About a year ago, my then-husband was driving the car and said the water pump went out (the bearings). He parked it at a friend’s house immediately and it sat for a few months; then we towed it home.

What to do if your Taurus is stalling?

Before troubleshooting any automotive issue, including stalling issues with the Taurus, make sure that you check the vehicles trouble codes with an OBD2 scanner. Trouble codes are always a great place to start diagnosing problems on today’s modern computer controlled vehicles. Without them, you are in the dark. These codes are vital to diagnosis.

How does a Ford ignition module work on a car?

The computer then takes the signal and the pulse rate and determines the rpm. The computer sends a signal to the control module when to fire the coil. The control module automatically controls the dwell for sufficient saturation of the coil windings to give the proper spark duration given the rpm in real time without creating undue heat.

Do you need to replace the ignition module?

If the plugs are alright, the module should be replaced. They are not expensive, however, they require a small special tool to remove the torx screws in the module housing. If there was no misfire, but the vehicle is hard to start or stalls, the module should be inspected and replaced if found to be faulty.

What should I do if my ignition module is cracking?

The module should be removed and checked for cracking around the torx screw mounting surface. There should be a thick film of dielectric grease on the back metal side of the module. This layer of grease keeps the heat off of the module.
