1990 Ford Engine/Emissions Diagnosis Repair Shop Manual Original

"Engine/Emissions-Diagnosis 1990 Shop Manual" This book enables you to diagnose the electronic emission control system for your engine. It starts with the Diagnostic Routines - a list of symptoms that identifies likely causes in order of probability. You then use the diagnosis flow charts in the book to 1) identify a symptom 2) run a test and then 3) choose what to do next on the chart based on the outcome of your test. Some of the tests you can easily do yourself, while others require diagnostic equipment to identify trouble codes. You will find pictures of the sensors and other emissions components, along with descriptions and some part numbers. You will see wiring diagrams for many engine-related circuits along with connector pin usage charts. This manual is primarily for diagnosis. If a mechanical operation is required to correct the problem, you may need the shop manual for your vehicle in order to make the mechanical repair (for example, how to install a particular sensor). If you have trouble finding a particular component, see the Electrical & Vacuum Troubleshooting Manual or wiring diagram manual.
