| V.I.N. | Motor | Type | FFV |
|---|---|---|---|
| 1 | 3.0L | OHV | ✔ |
| 2 | 3.0L | OHV | ✔ |
| S | 3.0L | DOHC | |
| U | 3.0L | OHV |
- FFV -Flex Fuel Vehicle.

Ignition System Specifications
The 3.0L DOHC Ford Taurus uses a distributor-less ignition system (known in Ford-speak as EDIS). This system uses a coil pack that has 6 towers.
This coil pack is made up of 3 different ignition coils (with two towers each) within the same assembly. Each ignition coil (within the assembly) fires spark simultaneously in a type of ignition system known as: waste-spark.
| Spark Plug Wire Resistance Specification |
|---|
| 30 K Ohms max for each cable (above 30 K Ohms and the cable is defective). |
| Spark Plug Gap |
|---|
| 0.052-0.056 inches (1.32-1.42 MM). |
| Base Ignition Timing |
|---|
| Non-adjustable. |
| OE Spark Plug |
|---|
| Motorcraft AWSF-32F (OE) Motorcraft SP432 (equivalent to AWSF-32F) |
The coil-pack ignition system of the 3.0L DOHC Ford Taurus can be easily tested. The following tutorial will show you how to diagnose the ignition coil pack in a step-by-step way: How To Test The Coil Pack (Ford 3.0L, 3.8L, 4.0L, 4.2L) (at: easyautodiagnostics.com).
