Cummins m11 injector code

Hard to say,need to run a cut out on it.
Most of the time,the electronics last the life of the injector.

 

SID 2 is the number 2 injector driver, without knowing the FMI, I cannot narrow it down any more than that. If you can't get an FMI, can you pull the flash code? That will help.

Disconnect the #2 injector and ohm it out. I don't know the exact range off the top of my head, but compare it to the rest that are not coding. Also check the neither of the wires have continuity to power or ground. If that all checks out do the same for the harness.

 

0.5 to 1.5 ohms between - and + posts. You can also check for shorts from each injector post to ground, they should both be open.

 

222 is the barometric pressure sensor voltage low. You're probably not getting a flash code for the injector because it's not active when you pull the codes. Being an intermittent problem, I'd look for a wiring issue first. Seeing that you also have a voltage code for the baro sensor, you may find a wiring issue causing both.

 

I've had bad injectors on a '98 M11 Celect plus where they are fine at no load but they miss under load. They didn't throw a code and they didn't respond to a cut out test.

Found which one it was by (finally) talking the KW service manager into hooking insite up to the data port and going for a ride with a load on. I was driving but I guess Insite measures the flow of each injector individually or something like that.

 

We have had this same issue a numerous amount of times on m11, we usually find it to be an injector. The harness for the injectors is not to pricey. If you can't narrow down to one injector replace the harness first or remove it and ohm each wire and out see if they are similar or one is really high and then decide to replace or not. My bet is an injector though if it's missing
