How Do I Read 1995 Ford F150 Check Engine Codes
The Ford F-150s made in 1995 have check engine lights that come on when the computer system in the truck senses trouble. Sensors send information to the power train control of the truck when the information does not match up to what the trucks known limits are. The trucks computer generates a code and displays the check engine light. Each code refers to a specific issue that can be pinpointed once you have retrieved the code from the trucks onboard diagnostic system.
Instructions
- 1
Remove the cover off the diagnostic port of the Ford, located under the dashboard on the left-hand side.
2Plug in the OBD scanner into the link of the diagnostic port. Code scanners can be found at your local auto-parts store. You can also ask a local auto-parts store if they can plug in a store-owned scanner for you to check the codes.
3Run the self-test with the code scanner. Read the manufacturers instructions to find out how your particular scanner runs the self-test.
4Write down the codes as the scanner reports them. There may be several codes--allow the scanner to run through the entire test.
5Move through the codes as they appear, but do not delete them.
6Remove the data cable and replace the cover over the port when complete.

How to Read Metric Thread Pitch
The definition of metric thread pitch is the number of threads per millimeter. That means that if the size of a metric bolt is M3 .05, then there is half a thread every millimeter. That information is great if you are at the hardware store and you know what size you want. In order to know what to buy, you still have to know what you are looking for. With a little common sense and the right tool, reading metric thread pitch is something anyone can do.
Instructions
- 1
Hold the fastener in question with one hand. Hold one set of teeth from a metric thread gauge up to the threads of the fastener with the other hand to see if they mesh.
2Alternate the sets of teeth from the thread gauge, if the first set does not match, try different sets of teeth until one of the sets of teeth on the gauge meshes perfectly.
3Read the size stamped on the correct set of teeth. The second number will indicate the thread pitch.
