    Got a hold of one of these today got it all registered up and plugged up and good to go looks like it's going to be a pretty capable little tool here looks like it'll handle brake bleeding etc at least on the generation 2 anyway that's all unplugged up into an interested in It gets quite a better app than the AP 2500 which I had before and was very dissatisfied with It looks like the AP200 is a light version of one of their most capable tablet scanners by directional tools so first impressions are reasonably good for me anyway

    Not sure about that but I will look today. You are talking about for the generation 3 where it gives an HG measurement of EGR flow across the system? I'll take a look if anything it's going to be in the freeze frame date or something like that I don't think there's a EGR test per se and then I don't know what the flow numbers that would be good or correct or what have you would be in the first place

    There are two ways it might be able to give you EGR info.

    One is to just ask the car for the result of the last self-test it already did. That's just a "mode 6" noncontinuous-monitors result query, and lots of scan tools can do that. I'd guess this one probably can to.

    The other is to support active tests, where you can command the EGR valve to a specific position. You can do this as a rough test while the engine is running, to see how far you have to tell the valve to open before the engine runs roughly or stalls. Or, if you've just recently had the valve apart and you're holding it in your hand with the plug connected, you can command it open and closed just to be sure it still does that.

    How about tpms sensor introductions?

    The step test can verify the gen3 egr system is not totally clogged causing no change in map pressure and can verify the egr is not sticking open at low rpm’s causing engine misfires or roughness.

    You will get P0401 eventually for either condition but the egr step test is easier than blocking the egr flow to rule out continuous egr flow as the cause of misfires and gen3 death rattles.

    In general it would be interesting to know what bi-directional tests the low cost Autel AP200 is capable of doing.

    There is a video of a guy doing this exact type of test on a Ford EGR valve with the dual hose feedback sensor I can't remember the initials of the sensing system and all that but he's showing exactly that I'm not seeing specific numbers but I'm seeing him command the valve to open seeing the vacuum is present at the valve for it to open and then looking for the engine to run rough and or die stall whatever but I haven't done it to my generation 3 sitting out here because I'm still playing around on the generation 2. I was just hoping for on the fly internal actuator brake bleeding without having to drag around a laptop and that I think of got covered and for $58 or whatever the thing is and can do that that's a blessing in itself unfortunately the stupid thing is white or the AP 2500 is black and red I mean this thing is going to look like well the toolbox very quickly but that's okay with me just seems poor on the design people You don't see a lot of snap-on and Matt go tools in white

    AFAIK, the AP200 should do that (write TPMS ID codes to the ecu) Plus brake bleeding, immobilizer functions, and some type of relearn for brake control (not sure if it's just steering angle sensor zero relearn or what).

    It shows me that I have TPMS codes but I'm not sure how to strike up a relearn this is in a car that I know the sensors are bad in the gold car four new sensors are installed I don't know what number sensors are on which position and I didn't even write them down. So I need a tool that can strike up a relearn with the car and let the car scan the sensors and log them in or not I don't know. Most of this brand TPMS tools are predominantly to work with their brand of sensors It will do minimalistic things with other brands of sensors so I'm not sure what this brand of scanner will do with universal TPMS sensors or our Pacific brand matter of fact let's go out and try that right now on the car with the four new sensors.

    These cars won’t scan sensors for ids to be used in relearns. Later models do that and require no scanner when changing tpms.

    However most good tire shops have tpms tools that can read ids and then program them.

    The 200 allows me to read and see everything about all four TPMS sensors including their serial numbers are registration codes so with that information now I can drag out the tech software and manually do it at least I don't have to break the tires down to get the numbers off the sensors if that's any consolation but it does bring up the brake bleeding menu so it's a decent scanner and it'll bleed the brakes without dragging out the laptop so for $55 or something I guess it's a semi win-win It shows a lot of things but doesn't allow you to tweak or adjust most of the things but given its compact size and it can carry it in my pocket read the codes of any Toyota Prius that I stick it into that's reasonably okay with me so it looks like it's also going to work with most other Toyota models that I might come in contact with and that's okay all without having to drag out the CF-13 tough book that's pretty okay so I can't see the EGR flow big deal takes a second to block that off and see if something changes..

    Those will be the old sensor ids that were previously written.

    I hope not because the numbers look funny enough like they match one of the Pacific sensors that I put in . I'm getting ready to have to put new tires on the car here in like 8,000 mi so when I do that I will have the tires off again and I can take a scan of each of the stupid sensors and see if what this dumb thing is showing me is sensors that have been out and removed for almost a year now or whether these are sensors that are being seen right now I know that all of them were dead that were removed all of the ones installed now on the AP200 app are showing pressure and showing a signal or whatever they're just not registered to the vehicle sensor ID number one is showing 30 lb on the vehicle and I think if I go out and put my manual gauge on the Schrader valve that's going to show me the same 28.9 or whatever it is sensor ID number two is showing similar pressure and if I turn the gauge mode on for the two it even shows the pressure on like a gauge looking device and it's even trying to make adjustments for the temperature whatever so yeah I'm sure they could be the old sensor numbers I guess that's possible like I say I've put the TPMS so far out of my mind I don't even look at it anymore but I'm going to do a actuator in about an hour and I'll know if the brake bleed works very quickly. Which to be real honest is what this thing was purchased for for the most part that and being a stout code reader I wasn't really expecting a lot of bi-directional and a lot of input for me like the Toyota software this actually isn't even like the MD 808 software that is one of their very capable scanners that the a 200 is supposed to be the light version of. Well it doesn't seem that's really so but I can see why they would tout that in the literature It's the easiest thing to do.

    Didn't your tire guy initiate the new sensors you installed using his magic wand or some such nonsense?

    If you don't have the ID numbers on your sensors, you would need access to a TPMS tool that can ping the sensor with a radio signal. (Autel TS408 or TS508).

    Assuming the sensors work, they should respond to the tool by sending the ID code, pressure, temperature, and battery status data. Fancier tools can directly plug into the OBD port and upload the IDs.

    Otherwise you use a capable scantool (AP200) to manually enter the IDs.
