Which Code Reader to Buy ?

[TC_Z]

We have a 2007 Winn Voyage 38J on a W24 frame. Three times now over a 2 year period i have gotten the REDUCED ENGINE POWER warning. Thankfully turn off and turn back on and it goes away. The check engine light is on for one ignition cycle then disappears.

It is not practical for me to take MH to an auto parts store to get the codes read. So I want to buy a basic code reader to look at history and see what the fault was to give me a clue what to check.

I was amazed at the range of features and prices, some hand held and some bluetooth to phone app. I don't want to monitor anything while driving, not trying to assess engine performance, but do want error codes.

And I am assuming all OBD code readers plug in under Winn dash no problem, no adapter needed, right?

What reader do you folks suggest I consider?

Thanks in advance...

Do all scanners have the ability to pull up historic fault codes?? Codes that have triggered a check engine light in the past but are now clear. That's my situation with my REDUCED ENGINE POWER warning. It happened last week but is now gone.

Or is this historic look back a feature I must look for that some models have, but not others?

Thanks

This is what I do too. I bought a $15 bluetooth ODBII adapter from Amazon and spent $5 for the Torque Pro app. It reads and clears codes as well as the real time vehicle data it reports. The Torque app provides links to find out more about the code(s) that are read.

OBDII codes can be read at obdcodes.com.
I used my cheapy harbor freight unit to read the codes, then go online to figure out what the codes mean.

The ODBII Bluetooth adapter is another way to go. I have a buddy who runs it, with TORQUE on his iphone and is very happy with all the live info he gets from it.

The ones I have are the ones the TORQUE manual warns "Cheap E-bay may not work" or sure look like it. Work great (I had some that did not)

NOTE: TOrque on a Android Tablet makes a very nice "Glass Dash"

Get one that will read ABS and Transmission codes as well.

Our previous motorhome was on a Workhorse chassis and would on occasion pull that stunt. Spent hours checking harness connections to no avail. Did notice it would happen more often (not always) when engaging or disengaging cruise. Turning it off and back on always cleared it. Don't remember the codes. Do remember they seemed unrelated to reduced power and were different each time. Our current Ford chassis rig has behaved much better.

Correct, if your vehicles engine uses OBD-II ! Heavy Duty truck use something different.

I have a small Bosch code reader. It displays the code number and an explanation describing the code. You can delete the code if you wish. It's worked well on 3 of my vehicles. It's been a few years, but I think it cost around $60 at O'Reilly's. Hope this helps.

I bought about the cheapest meter I could find the first time, and while it did the job, it didn't show exactly what the codes meant. It just showed the codes and allowed you to delete them.

The one I have now, a Launch Creader VII, works very well, and tells you what the codes mean. Very handy. I paid less than $30 for it a few years ago. Since the newest vehicle I own is a 2013, I have no idea if it will work for the latest and greatest gadget loaded new vehicles.

I know the Autel ones work. I have an ML 629 in my truck which also reads transmission codes. And a little 319 autel that I keep in the second car. It's a basic unit ansd seems to work fine.
