OBD2 Scanner CAN OBDII Code Reader - Scan Tool for Check Engine Light - Universal Diagnostic for Car, SUV, Truck and Van (MS300)

I bought this because my check engine light came on instead of going to a mechanic I bought this and all it was is my gas lid wasn't on right thank goodness I bought this so my friend barrowed mine so I bought a second one

My Lincoln Town Car started flashing a check engine light and then the light turned solid. I bought this OBD II scanner to check the code. The code scanner was very simple to operate. I just attached it to the OBD port under the dash of my car. As soon as you connect the scanner it powers on with a nice, bright green display screen. I turned the ignition key one click forward to the ACC setting and selected the DTC (Diagnostic Trouble Code) menu and told the scanner to begin the scan. It returned trouble code P0308 for my town car. A quick check in the included manual for the OBD scanner, revealed that the code was for an ignition misfire on cylinder eight in my car. I knew that my car had coil over plugs, so I ran down to the local auto parts store and bought the part for $44 and thirty minutes later my car was running perfectly. This scanner literally paid for itself the very first repair. I hate to imagine what it would have cost for me to take it down to the dealership for a diagnosis and part replacement. This scanner doesn't only allow you to read the codes, but it also allows you to reset the code, so you can confirm that your vehicle is working properly.

This item works; it does what it was designed to do, which is to scan your vehicle's OBD system and display any diagnostic trouble codes (DTCs) detected. Now, I am only extolling the virtues of the code scanner that is BLACK--some reviewers commented on receiving an item (in RED) that differed from the picture listed for this particular code scanner, and I can just about confirm that it DOES make a difference. I have a VAG305 code scanner for VW/Audi that is similar in design to this scanner; however, it is definitely VW/Audi specific. I tried to use it on a 2003 Toyota Avalon to no avail--kept getting the "link error" message. At this price point, I believe that this is a good deal--just make sure that what you receive matches the picture.

Worked for my 02 Ford Ranger. Displays any fault code and the 'readiness' of your emissions system. If you didn't know, the DEQ will turn you away if you cleared your codes and haven't taken the vehicle through enough drive cycles. Wish I would have had this when I was buying a used car, as you can see if someone recently reset the system and is trying to hide something.+No batteries - is powered from your car.-Comes with book to lookup the codes, since the monitor only displays the code number.+displays ODB2 'readiness'+displays VIN information+Can clear codesI read about some people having problems with theirs. But if this one ever gave out, I would probably just buy the same/another cheap one.If you want to investigate your Check engine light and don't want to keep borrowing the one from the auto parts store.Great value for the money. I would recommend this product.

I got this scan tool specifically because my wife's truck had a check engine light on and needed to be smogged. The smog shop wanted $70 just to run the code. I hooked up the scanner, found the code, looked it up online and saw that it was the mass air flow sensor. Cleared the code, got the $60 part and replaced it without issue. For a total of $72.89 I was able to fix what the shop would have charged over $300 to fix.No this doesn't have all of the fancy options that describe exactly what the code is and how to fix it, but seeing as how I have a phone in my pocket that can access the Internet if I don't want to walk all the way into the house to use the computer...I see no reason to pay for a fancy code reader. All I need is a unit that will scan for error codes, tell me what the code is, and clear the code if necessary. Perfect and simple. I would highly recommend this unit to anyone who has ever thought they might possibly need one. For $13 and free 2 day prime shipping, you can't go wrong. Even if it only lasted for a single use, it's already five times cheaper than having the code read at a shop.

As the cheapest scanner on Amazon, I had to double-check the reviews to make sure it did actually read codes. Besides some connection errors, most said it was just a simple, bare bones scanner that spits out a code. That's all I wanted. So my check engine light comes on (2008 Saturn Astra, 140,000 miles) and I am partially annoyed and partially excited to see if this thing works. It connected fine, identified the proper scan protocol, but said "no codes".After some research I discovered this is sort of rare, to have a check engine light but no codes, and can sometimes be the product of a cheap scanner. I was under the impression this was sort of binary...either it connects to your car and reads codes or it doesn't. Mine will connect to the car, but will tell me there's no codes. Took the car to an Autozone to confirm, and sure enough there's the ole P2096 "post catalyst fuel trim too lean". God knows what that means but I learned my scanner doesn't work.Not planning on returning it, because it was so cheap and it's not a bad thing to have in the glovebox for a future car, or maybe a friend's car. But it doesn't work for my current car. Maybe someone with some more automotive knowledge than me can devise a way to tell which cars are compatible with which scanners - it is NOT all engines made after 1996, as advertised.Now I need to go figure out what a lean fuel ratio is and how much it'll cost me to fatten it up.
