Title: Contains nothing unique or insightful
Product review: As others have said the book's contents are available online for free.For do do-it-yourself repairs you need to know the possible causes of the DTC Codes. Obviously this data would likely be different for each vehicle model and year. For this info you must either have the factory service manual or go online and search for this info using the DTC code along with your vehicle's model and year. It is probable that others with your same vehicle model and year have experienced the very same code and they will share their insight.Sometimes the "Service Engine" light comes on and the corresponding DTC code indicates the problem is an "emissions system fault". A very common emission system code on most cars can be remedied by simply tightening the gas cap. Seriously!
