2010 maxforce 13 will not do passive regen.

Totally off subject, but then maybe not. Romney was going to try to reign in the EPA, which is the reason for your woes!

Check the fuel doser and replace it. The nozzle on them tends to plug and stick, there is also a new gasket for it with a larger hole for the nozzle tip to prevent plugging. If the predoc is damaged it will cause frequent regens, this is most likely due to a failed doser. Make sure the ecm is at the latest cal and there is no exhaust or boost leaks.

 

the ETV to head seal tends to leak. They have grey RTV there and blows out, they make a metal gasket now for it.

 

So what was wrong with it am having same exact issue

 

Several things will cause no passive regens. We have found fuel delivery pressure slightly too high. There is a grey area where the ECM doesn't like high fuel pressure and will not allow a regen to start, but not high enough to log a code. If your fuel delivery pressure is over 120 psi you will have regen problems. We have seen corrupted body controllers give the engine false regen inhibitors so a regen will not take place. Severely dirty or plugged aftertreatment injectors will cause this. There are many more, but you basically need to plug into it to see. Unfortunately, there is literally nothing a owner/operator can do without diagnostic software to see what is going on.

 

Im having the same problems, dealer wont check parameters
Had high and low temp egr coolers replaced, computer upgraded, ati (doser valve) replaced, dpf filter cleaned, still multiple regens. Overheard a "mechanic" say the last time I was at the deal, that nobody had their ASE certification, and he was upset that he couldn't get a raise, need to find a real technician!

 

Technician talent is becoming a problem and dealers do not want to pay. Our door rate has increased nearly $30 in the last 5 years and we have not seen any of it. International has cut back the warranty times so bad it is impossible to make a profit doing most warranty work. Dealers avoid it as much as possible.

 

Do they pay you guys flat rate or by the hour? My last gig was hourly but the regional service manager started imposing all these insane job times on us. Really hard to diagnose an issue in under an hour when you've been on the phone with the manufacturer's tech support department for almost an hour and they basically tell you "good luck, we don't know what we're doing either!"
