The sensor looks identical with VDO 5Wk9700Z. In Europe, auto parts shops sell it for 1/3 of the OEM part price.

uphill on the end of the video is very nice :) Btw your bike has mega torque. Love it!

Amazing channel - I don't even have a model where this is an issue, but this is a masterclass in wrenching anyway

Thanks and pleased that you enjoy the videos.

Great diagnosis test...! Now, don't stop here. Check that sensors electrical function too. If it also reads accurate pressure changes (in line with what pressure the crank case produces) then by process of elimination the tray seal you fixed must have leaked.

Hey thanks for the shout-out! Appreciate the credit bud! Good idea to take it a step further and hopefully this helps some people.

No problem and watched your video with interest. Hoping KTM can figure out a way of improving the reliability of the CCPS system. Seems like many people are having problems and when it goes bad it's not fun to ride... :-(

@@TokyoOffroad definitely agree. It's too bad we haven't heard more from KTM on this issue. I've been pretty unlikely with them, so I'm also following your channel closely 👍 cheers 🍻

I am glad that you are still looking into this. It is like the failing gasket on the mikuni. It took a long time to diagnose the actual issue.

I think the issue is the rapid change in + and - pressure, and air/oil mixture entering the hose.. but what do i know... my bike has about 300 hours on it, about 100 of those with a bad sensor..

Can you come up with a test procedure using your pressure testing rig? It would be good to have a method of checking a sensor to see if you get the proper read out per a specified pressure input.

Another legendary video. Thanks

Is the sensor just a variable resistor ,if so for a quick fix could a fixed resistor in the "sweet' spot be used for trouble shooting ?

Spread epoxy on the case to seal it where it's assembled. Also I'm working on a filter screen to put between the motor and the sensors. Oil residue build up in there.

Also curious if you came up with anything

I had this CCPS issues twice. I suspect it is related to the fact that prior to symptoms I filliped the bike upside down. It seems that oil may entered to the sensor. First I replaced between the sensors. The second time, because of backorders I purchased Automotive equivalent from Aliexpress 15$. It works great!

Could use a "Brake Bleeder, Steering Pump Bleeder & Vacuum Pump Test Kit" as I do which I bought at an automotive store. It is labelled as brake bleeder. Had it for years. Cost approx. $80 CDN.. It is a hand pump with a gauge, hoses, fluid container and various hoses.

I wonder if you also could use gas leak spray while it’s pressurized and look for bubbles.

Based on all the threads and research people have done on the sensor it is obvious this sensor was designed for use in cars. Kudos to KTM for using off the shelf parts but it probably needs to be more ruggedized for use on a dirt bike. Your typical car is not going to experience the shock and vibration you get on a dirt bike.

Will you be selling your brass fittings? Also, do you think an overpressure moment in the crankcase could be causing these sensors to fail? Seems like if that happened the o-ring part of the unit would likely be overcome or move or cause the housing it fits into to swell and therefore begin to leak. Just thinking outloud.

Thanks for your interest. Yes, I have just started selling the brass CCPS coupler fittings. They're available from the Tokyo Offroad webshop (shipping from Japan), or if you're in the US you may like to purchase from Taco Moto. The kit includes a couple of much easier to use hose clamps and instructions. Note that modification of the plastic tray is required: www.tokyooffroad.com/product/ccpscoupler/ tacomoto.co/products/tokyo-off-road-tpi-ccps-coupler-kit?_pos=1&_sid=ed1d6da87&_ss=r I doubt the sensors are failing due to overpressure, but would need to perform failure analysis on one to know for sure.

Are you going to offer the custom fitting you made on your store front? Seems a much better mount than OEM to hopefully prevent future issues with the CCPS

I shipped a couple of brass fittings to customers last week who made strong requests. Yes, I'm planning on listing the fitting on the Tokyo Offroad webshop in the next week , or two. It should be noted that the tray needs to be modified (12mm hole and about 18mm diameter of 1mm relief on the top side) for the brass fitting to be installed. To create the relief I used a milling machine with a 18mm end mill, but a rotary tool could be used if you're careful.

Did the engineers deliberately put this in the most awkward place possible?Can’t see any reason why I can’t relocate it;bolted onto the head steady.2 minutes to replace im guessing.

Ktm has been silent on this issue and right now you can't even get a replacement sensor. Would it not be better to run a hose directly fitted to the sensor, eliminating a possible leak at the tray connection?

@TokyoOffroad

As I mentioned in the video, attaching the hose directly to the sensor chimney may result in a better seal, but may be difficult to keep secure (as there is no barb). I’d be concerned about long term reliability as the hose is quite stiff and may result in the sensor chimney cracking, or breaking off.

Hey mate you say you don’t recommend spraying anything into the sensor. I had an issue with my sensor and i sprayed maf sensor cleaner into it and it actually fixed it

@TokyoOffroad

Typically this type of sensor is not designed to handle solvent entering the sensor and doing so may result in damage, or performance degradation. This is why I recommended not doing so in the video. But if you have a non-functional sensor which bunged up with oily residue, that’s not to say that trying to cleaning it out might get it working better, but it might further trash it too. If it’s really not working well I guess you don’t have much to lose by trying.

Yes, my pressure sensor package was not cracked. Internally there must have been an issue, or the seal between the sensor and tray wasn't good.

Someone please help. I’m not an expert but decided to remove my tray and have a look at my sensors and tbh both were pretty dirty and CCS had petrol in it ( It was wet still and smelling ) bike is running poorly and fouling the plugs very often. What should I do? Thanks

Sorry to hear about the problem. If you have a new CCPS install it and see how it runs. If you don't have a new sensor you could try swapping the Atmospheric pressure sensor in the CCPS (they are exactly the same part number). Also clean out the CCOS hose and fitting. Some people have reported that the plastic tray sensor housing does not create a good seal with the o-ring, so inspect the area that the oring seals against. I do sell a brass coupler which can be installed in to the plastic tray to help ensure a good seal (note that the tray requires modification- do sell modified trays to).

@@TokyoOffroad thank you for your quick reply, I don’t have a new sensor and I reckon I already mixed up both sensors when cleaning and now don’t know which is which :/ about the brass couple I didn’t know you selling them but after seen your video I searched and bought one from Ali and now just waiting to install it, one thing I didn’t mention and you probably be able to help please. I’ll paste here if you don’t mind my question Imon ThumperTalk which had no answer yet. You could be of any help I much appreciate it. “Hi fellas, I’m not an expert at all but decided to give it a go and try to fix my bike ( ktm 2020 tpi 300exc) the bike was running poorly, bogging, fouling plugs etc so I removed the tray that holds both pressure sensors and it was super dirty but what made me wondering was that the crank case sensor had fuel in it like it was wet still and smelled petrol. Anyone knows if my sensors are &%$#@!? Is there a way to test them? Another thing is when I removed the throttle body it had a lot of 2t oil in it and I also realised the pipe and exhaust full of oil like the spark plug. I bought this bike with 119hours and was told it had top end done at 110hours, she was running great for the first 8hours but now is just a pain in the ass. Any help is really appreciated. Thanks.”

i sprayed alcohol inside my old sensor and blowed it directly with high pressure air gun. it made no difference at all. bike was still having stuttering issues until i bought new sensor

What is your favorite ktm year..pre Tpi or Tpi?

In Japan the KTM model year 2017 was the last year of the 2-stroke carb bikes and first year with the engine balancer. Stock the 2017 was not very good (Mikuni carb ran horrible and suspension setting was soft and felt unstable at speed), but once modified to overcome these shortcomings the 2017 is a very nice bike to ride and I love riding mine (Keihin 38 with STIC, Dal Soggio Sphere cartridges, Ohlins TTX shock). Regarding TPIs, I think they have improved steadily since the first MY 2018 bike. It'll be interesting to see how the development continues with future models.
