The Haynes Obd-ii & Electronic Engine Management Systems Manual (1)

The mysterious electronics and black boxes under the bonnet simply explained and than are just plain sense. Great book to understand car emissions and electrics. Explains in simple terms what every black box, sensor, actuator, etc does and how it works. Explains how to test all of the above with both multimeter and fault code reader/scan tool. If you like to look after your own vehicles, get this book and a fault code reader and wave goodbye to main dealer and mechanics prices. Although I didn't have an engine warning light on the dash, the car was not running right and using more fuel. By looking at the live data on a hand held scanner I was able to trace the problem to the O2 sensor. Book took 10 days to arrive. Worth the wait.

Got this for my hubby as he is a mechanic

Previous buyers slated the book , however if you have a basic understanding of simple battery / earth in dc circuits I believe this book will be of great value to you. If you only read it , without applying any of the test procedures you will have a much better understanding of all the engine management systems of your vehicle especially the wall important emissions section.

Comprehensive book full of the relevant information to help diagnose problems with most modern vehicles

Brought for my Brother to go with the OBD-II I got him for Christmas. Says he loves the convenience of having all of the codes on the seat next to him and not having to worry about getting his phone dirty trying to look them up on Google :) Thank you!

Great book but only for US cars and no diesel engines, so it's limited to gasoline. But it's a great book for those specific types of cars

good book.

Good book, maybe beyond me.
