Review on Unleash the Power of OTC 3108 PocketScan Code Reader: Scan with Ease and Efficiency! by Mark Allen

My 2002 Ford Escape XLS failed the test after the battery died. My mechanic kept telling me to keep going. This device told me that the catalytic converter was finally working. I was finally able to pass the exam. I didn't have to constantly go to my mechanic to check if the exhaust sensors were ready. It worked great on my 2002 Ford Escape XLS and 2011 Honda Accord V6 EX-L.
