[@CarlosDieselElectric]

Bad Guy I believe with this issue it was more of a symptom rather than a fault code. But when you have a fault code it would say something like Intake Throttle Valve deviation. I don’t remember exactly what the fault code or codes could be.

I have a code, Engine 2 SPN 102 FMI 18 on 2016 dd15 cascadia I changed the intake manifold temp sensor, code cleared but came right back, took new sensor out ant it has soot all over again, any suggestions if you've ran into this problem.

[@CarlosDieselElectric]

Quick google search comes up with "Intake Manifold Pressure Lower than Expected Under a Load. Monitored Parameter" Check your CAC, check your venturi pipe and the ports for blockage. Also, if all those check out then run a parked regen and see what the numbers are. The DOC Inlet Pressure might suggest One Box issues. Excessive soot can be from injectors, valve adjustment so also have your mechanic run and idle speed balance test and see if any injectors might be off.

Low boost, recommend to check the Charge Air Cooler (pressure test) first before you replace the EGR actuator. If you have a leak this will cause the low boost. Start there

Hey Carlos, this morning I got a code on my 13 Cascadia (eng 2 001 3464 throttle ) and I kept working thinking I would get to it on my day off. Everything was running good until I got to my last load and my truck would release a lot of black smoke on the higher rpms. The fault code is now gone but the smoke is there. You think that smoke has to do with the throttle valve?

[@CarlosDieselElectric]

george saucedo could be related. Has anyone plugged into your truck to read the actual fault code? If it is the ITV, this could cause issues. Remember things work electronically and mechanical, so electronically it could register properly but mechanically it could not be doing its job correctly. I’ve seen that happen many times.

[@josedeleon1573]

As a preventive maintenance, can you clean these if dirty? Like cleaning throttle body on cars. Or not recommended?? Tbanks in advance

[@CarlosDieselElectric]

Jose Deleon that is a great question, you could try to clean the throttle valve but if the valve gets stuck you may still have to replace it down the road. Luckily the price of an Intake Throttle Valve is pretty good. For a new one you are looking at around $175 or a factory rebuild but I don’t recommend those.

[@gaelrico6681]

Quick question does the Intake Throttle Valve activate the EGR system? Also great video!

[@bhadd3418]

Hey Carlos question how would the truck run if your having throttle valve problems?

[@CarlosDieselElectric]

Bernard Haddock typically there is fault code. Active would give you a Check Engine Light or Inactive, but you need the the Diagnostic Link Software to see. Now physically the truck at idle may seem like it is dying as if fuel or air is not reaching the engine but when you accelerate it responds. During a regen (parked or driving) they maybe a surge or seem like the engine is hunting trying to stabilize at a certain RPM. You could use the software any manually control but that has its limitations.

[@bhadd3418]

Ok can this effect your egr and turbo actuator performance?

[@CarlosDieselElectric]

Bernard Haddock possible since the ITV maybe closing instead of staying opening or not doing what the MCM ( computer) is commanding. What kind of truck are you working on? Do you have any fault codes? Active or Inactive?

[@bhadd3418]

@@CarlosDieselElectric 2009 Freightliner Cascadia DD14 60 series I have DPF and EGR no DEF. But I had a fault code for a bad relay they switched the relay out and I thought that was the problem because they told me that's why the check engine light was coming on. Now a few months ago I had a DPF fault code the told me it was the EGR and got it replaced and that EGR was bad so they replaced it under warranty ever since I've been having problems! And I took it back to the shop and it was saying my egr was stuck close along with my turbo actuator valve restricted operabilty but they both were inactive!!

[@CarlosDieselElectric]

Bernard Haddock how is your engine harness? Is there oil contamination? Disconnect the injector harness on the driver side and check for oil. Also at the MCM on the 120 pin, remove and check for oil contamination. If oil is present then this could be the reason. Have any of the harness’s been replaced ?

[@AA-bk8qg]

Would this cause rough idle ?

You can connect the software and run some tests. This will allow you to see if there are any inactive or active faults. This is important to see the history

[@ivanpalamarenko3729]

Hi ! I have 2016 Cascadia 350k miles. My engine feels like have some restriction to rotate sometimes, like it’s trying to adjust something and shakes more on Idle and turbo reads1-2 psi. (boost sensor replaced) When holding pedal steady at some 700-900 rpm It could start climbing with noticeable quieter vibration and resistance or drop about 50-100 rpm and more noise and vibration. When holding 1500rpm sometimes turbo reads 0 and highest I see is 6 psi. Same thing while driving downhill with no engine brake at1500rpm 0-6psi. When driving it’s also vary, sometimes it’s loose speed quicker and sometimes it’s going like crazy with much louder engine sound. Turbo readings also feels swinging sometimes and sometimes it’s pretty responsive to pedal. Working 23-27psi on gears 9-12. on lower gears it could hit 34 psi but after 9 gear it never get over 27 psi. In different places I been told All computer tests it passed as perfect engine, no any codes. MPG also jumpy and while doing regen time to time level of vibration and sound is different. Once it shakes so much so everything start falling from shelves. May it be trottle valve? Why no codes? Thanks for any answer or suggestion on what and where to look for.

[@CarlosDieselElectric]

I had something similar to this where the truck would have little turbo boost even with the accelerator all the way down. I used a test turbo and that did not change anything. I ended up swapping the MCM (motor control module), performed a road test and the boost came back. Try using a test MCM to see if this helps.

The MCM is the computer for the engine. Sometimes it is called the ECM. Located on the driver side engine just below the fuel filter housing.
