Thank you for your help I was able to find a used one in Canada and it worked Old Mack parts getting hard to find Just like Old Mack mechanics

I am looking for a 12ms45m5 ecm Any help or suggestions please

Thanks Mackpro that # is the updated # from the one I posted I got it 4 days later from my local Mack dealer 12 miles away P/S I ordered it from the Mack dealer 70 miles away at 8 AM and had it in the shop 3 PM the difference in a good dealer

Yes it is the pink stuff That explains why I haven't got it from mack yet they are mack only also I ordered the Loctite and activator wont be here till tuesday I am afraid to use anything but what is in the bulletin don't want to have to do it twice

Thanks again Mackpro One more question sealant for cups Mack part# 1161059 I ordered it from Mack on Thursday and still has not come in. I crossed it to Loctite #510 and cant find it without ordering. What do you use?

Installing new injectors and cups in 2012 MP8 I have Tech Tool where would I go to reprogram the trim codes and can I program the codes with customer level tech tool? In the past I couldn't program my 2012's but I can my 2014's That's another long drawn out story with Mack the Government and Jesus And is it important to reprogram the trim codes

I am thinking throttle position sensor Without scanner or computer to check throttle % I would try to turn idle up with cruise control switches but that depends on what your parameters are set at To change the TP sensor I could only buy the hole pedal at about $400.00

Problem code SPN 5246 Aftertreatment SCR operator inducement severity FMI16 data valid but above normal operational range moderately sever Then truck goes to derate Truck has new def pump and doseing valve

Well after one month of back order. I changed venture tube and sensor truck has ran with no codes Thanks Mack Pro

I don't think its just Mack Its just that's what I have if I had Pete or KW I would be on Bigpaccar.com

Well about them turbo bolts. When this all started with this code I cleaned the tube replace the sensor cleared the code and went for a road test. Empty ran great no engine light so I went to the quarry half way back the turbo locked up great 73,280 no turbo. So any way when I had the turbo off with the now broken bolts I changed the cooler and valve since they were never changed. So looks like I will be waiting for my new venturi tube

Yes Vevturi pipe is still original I checked with parts again last night he dose have a kit ordered for me but it wont be till late Nov.

Has flat plug with yellow slide lock

Yes I have cleaned them they were not plugged. I also changed the sensor I thought I would change the venture but my dealer says they are on back order.
