ANCELAD310 Classic Enhanced Universal OBD II Scanner Car Engine Fault Code Reader CAN Diagnostic Scan Tool, Read and Clear Error Codes for 1996 or Newer OBD2 Protocol Vehicle (Black)

My truck wouldn't start, just clicked when I turned the key. I checked all the fuses, checked all the sensors, thought maybe it was the starter. Because I couldn't drive it to a parts store to have them hook up their OBDII for free to tell me what the problem was, I was forced to buy one on Amazon. I bought this one for like $20. As soon as I read the manual, I hooked it up to my truck (so simple and easy) it immediately said "crankshaft error- code P0335". I thought "Oh no! A bad crankshaft! My engine is toast. What am I gonna do?" But when I googled the code, turns out it's just a crankshaft position sensor. Whew, that was a close one. Best $20 I ever spent.

This is by far one of the best low priced scanners that I have ever used.It's simple, fast and easy to diagnose problems that are keeping you from reaching the ready for testing state.After scrolling thru the readings, mine had no CEL's, it showed the O2 not completed.I then scrolled to the chart screen in live data, scrolled down to the bank 1 sensor 1 and was pleased to see real time data such as a scope shows, everything was fine. Next up bank 1 sensor 2, the first look everything was fine. Back to sensor 1 everything was fine. Sensor 2 on the second look it was flatlined. Again cycled and on the third look, the signal was degraded and fluctuating.Bingo, an intermittent issue.I had already ordered the replacements so they were on hand. Once I had verification from this scan tool I replaced them. You always want to replace the entire bank, even though only one shows faulty, the others will soon follow.With this tool it took less than 10 minutes to resolve my trouble.Thank you for a great product.Don

This is an inexpensive, basic scanner. If one tries, one can spend hundreds of dollars for a scanner with more bells and whistles. (As an example, I just returned a different IOT scanner that wanted unrestricted access to my WiFi router.) This scanner does not ask for my personal info. It does not need A WiFi connection, and does not send/receive email.Also, it draws power from the OBD-2 socket. It does not need to be charged overnight. It comes with a very nice user guide that explains how all the screens work. The display is in black and white, but has good resolution and offers several real-time graphing functions. The menu and set-up screens are intuitive. Once I got started, I had no problem navigating through the displays. I was able to view all the data I wanted to see, and was able to reset all of the codes that were causing lit trouble lights on the dashboard. In short, this scanner does the job and even offers some additional features that make it easier to use. This scanner is a keeper.

Quality through and through. Works like a champ. Read my code and pointed to the oil sending unit. Replaced the oil sending switch and fixed the problem. I'd like to address the fact that though it does clear the check engine light (you do it manually) rerunning the code check it still shows the same code. This is contrary to the instructions witch state after clearing the code recheck to confirm it is gone. This in wrong, misleading, and confusing to new buyers. Clearing the code does not do what you would think and what other inferior code readers do. The code remains until the problem is fixed and the car is run enough to complete its next computer wellness check. Then the code is gone. This is not stated in the instructions, but make sense to me as a problem with the car is not fixed by clearing the check engine light.This is a well make product and I would recommend to others. I am taking one star back because of the confusion with the manual. It needs clarification.

My car was having some engine issues, the light was on, and in order to pass my emissions test and renew my registration I needed to fix the problem.This tool helped me to diagnose the issue, after looking under the hood and using the error codes to guide me it was incredibly obvious and I decided to fix it myself. One of the air intake hoses from the filter to the engine had degraded and was split completely in half, and fortunately it was a readily available part and easy for a novice to replace.It wasn't obvious at a glance, and this tool led me in the right direction.For complete amateurs like myself, be aware that after making a repair you should clear the error codes. You'll then need to drive 60-100 miles to ensure that the repair worked and for the car's computer to register as ready for inspection.Long story short, this tool saved me a lot of time, a LOT of money, effort, and not only helped me solve a serious problem but kept me out of trouble with my registration.Manual is clear and easy to follow and the device is simple enough to use.

This was such a money saver. I bought a used car to drive to work and back and got codes immediately. Thanks to this, I didn’t need to pay a shop to diagnose and I was able to capture the code, find the problem and fix it myself. I keep it in the glove compartment for quick access. It was easy to use and accurate.

Did some homework on YouTube before buying. Does everything I need and was on sale to boot. Ordered on a Wednesday and arrived Friday. I was able to read and clear the P1450 code from my 2016 F150 2.7 EcoBoost. This device complies with the KISS principle. Since this unit is useless anywhere else, I plan to keep it in my glovebox.

Very nice little code reader. Check engine light on my 02 GMC Sonoma was on, read the codes, then I erased the codes. Very simple to use, well definitely come in handy for all our vehicles. I definitely would have no problem recommending to anyone.
