stop engine lite

Yahoo Message Number: 71146
After not using the coach for 5 weeks, I decided to crank the cummings 425hp engine to warm the oil. I noticed a beeping sound and the stop engine lite was on. the engine seemed to be running normal and had good oil pressure .
Any ideas why this happened and what to do next? 2008 Inspire

First thing to check is the coolant level. A low level will give a check engine light.
A word about running the engine to "warm the oil". If you can't drive the coach enough to get the engine up to operating temperature and keep it there for at least 20 minutes, you are doing more harm than you would if you had not run it. A short, low temp run creates moisture within and by not reaching operating temps, the moisture doesn't have time to evaporate.
Last weekend, with the temps in the high 50's, it took my ISC 85 miles of highway before the trans and engine reached 190.

If your surge tank is full, oil pressure is OK and the all temps are in the normal or lower range, it could be a bad sensor on the surge tank. The sensor is supposed to sense a rapid loss of coolant. If it goes bad or you really have a rapid loss of coolant it will illuminate the engine shutdown and engine check lights and if you don't turn off the engine right away it may cause the ECM to derate and shutdown the engine. A bad sensor shut down our C9 engine in LA during rush hour. No fun there.
After that experience, I had the sensor replaced and had the ECMreprogrammed so that the driver has to make the decisions regarding when to derate or shutdown the engine.

Although we have different Cummins, Ours a C-8.3 I had a problem with the Engine Stop Red Lite on the dash and the engine cutting out for a couple of seconds. I replaced both Fuel Filters and problem went away. I dont have a silverleaf. I cut apart both Fuel filters and found less then half of the Filter can had the filter element and the lower half just fuel these are fleet guard filter's. Working at Cat the filter can's are full with the filter element. I carry spare NAPA Filters. I would take the coach to Cummins and have them connect the Laptop and road test. They can check for code's. Would not hurt to have them remove your fuel filters and cut them apart for Inspection. Keep us posted. Ken Retired Cat Tech. 99 Allure 30356.

I am running the regen as i type this. I think everyone is correct about the problem being a sensor since the lite and the alarm come on before i even crank the engine.

The lite went off and everything seems fine after doing the regen. Still a puzzel why after a one thousand mile trip, the engine needed the regen.

Sam,

What was the process for doing a regen. on the engine?

Normally Regen is automatically done. You say it needed to be Regen'd after a 1000 mile trip. You can't say that unless you know when it last regen'd. I have not seem mine come on in 32000 miles, so I manually pushed the button at about 20 K miles. The exhaust pipe is always clean, so it probably was not needed. If you don't idle much or don't do slow in-town driving, it is likely to not need regen ( again it may need it more, when the miles build up ) The other point is that you could be driving down the road and not see the light come on. I would guess that is was an unusual circumstance. Those computers are great , until, it comes to fix them.

Dennis,

I started my 06 Inspire a couple of days ago to get ready for migrating south. I noticed the oil pressure gauge was pegged at max. I disconnected the sensor on the gauge and grounded it and it went to zero. I ordered a new sensor through CC and it should arrive today. I thought the oil pressure gauge was separtate from the engine protection (shutdown) system. I was considering driving it based on knowing the engine would shutdown if I lost oil pressure. What would have been the probability of me getting a shutdown if I had driven it as is? Also, do you have a suggestion for a source that would give me more information on the installation/location? I am trying to determine if I should remove the access panel while waiting for the part or if it can be reached from the ground.
I have been getting engine shutdown warnings. Most of the time it just cycles through one time and resumes normal operation, but it did shut me down once. Do you think this is related to my current problem? Cat and CC say they are separate systems.

Thanks. Randy Law. 2006 Inspire

Randy,

In the case of the low coolant sender/sensor failure that I experienced, when it failed the ECM shut down the engine. My ECM was programed to derate the engine and shut it down if the sensor failed or a signal from a sensor indicated a problem. Yours probably is programmed the same. In my case, the "engine check" and "engine shutdown" warning lights did come on intermittently for a few months prior to complete failure of the sensor/sender.
Your CAT and CC sources may be right about the ECM and gauges being separate systems, but I think the ECM and gauges are using the same oil pressure sensor/sender for input. I think they interpret "separate" to mean the gauge can fail, but the ECM and warning lights will still work OK.
In regards to location of the oil pressure sensor, page 6.8 (electrical systems group in Parts Section) of the Owner Manual shows the location of two oil pressure sender/sensors. The first one is for a system that needs an indication of at least 4 PSI for it to turn on and the other, I believe, is for the gauge and ECM.

If anyone knows for sure please pipe in.

Dennis,

Thanks. Found it. Of course it had to be halfway up the engine for harder access from either the access panel or ground.
This will be well worth the delay if it stops the occasional engine shutdown light. I guess I can consider myself lucky I did not get stranded somewhere. LOL! I've owned this coach one year, took three trips, and broke down twice so it would have been more of a standard operating procedure help call.

Thanks for your help and good luck with your coach.

Randy
