What causes a stop engine light N14 CELECT?
There is no charge for this service, but standard message and data rates may apply.

I’m not sure if the engine position sensor will shutdown immediately or give you a check engine light and a code as it dies.

What does the engine management warning light mean?
The engine management warning light is different from the other lights on your dashboard, as it doesn’t alert you to a specific fault. Unlike the coolant temperature warning or low oil level warning lights, the engine management light (EML) can be triggered for a number of reasons.
When did Cummins start using the N14 CELECT Plus?
Albeit the injectors are still cam actuated the ECM controls the metered flow of fuel to the injectors. In 1997 Cummins introduced the N14 Celect Plus which further fine-tuned the ECM to control many more custom parameters of the fuel system. In addition of an ECM the N14 was designed for emissions purposes to consume much less oil.
Why is my Cummins N14 motor having a problem?
One of the codes identified a problem with crankcase positioning sensor. mechanic replaced this and codes kept indicating it was bad. That was part of reason mechanic said it had to be the ECM.

How does CELECT fuel system work on Cummins N14?
The Celect fuel system produces systematic pressure throughout each injection cycle unlike the common rail fuel system of the 855, or older M11 or L10 models. Albeit the injectors are still cam actuated the ECM controls the metered flow of fuel to the injectors.
