Re: Code readers for 02 envoy
You can buy a scan tool for as little as $50, but those are no-frills and you only get the code number(s). Better ones will tell you the fault(s) in text and assess your emissions system...abt $70-$100. But if you're interested in repairing the trucks yourself, then Maxwedge is correct in that for good diagnosis, real-time data is the best. Those tools can run $150-$300, depending on the features you want...numerical data, graphical data, data capture and d/l, etc. But one tool can service all vehicles.
