That was a very interesting conversation.

Updates:

Jumping the pins on the pigtail worked for the coolant sensor. It looks like it is the sensor and not necessarily the wiring harness. I have a trip coming up in two weeks so I'm probably going to swap the jumper for a resistor and run that way for this trip. I'll be checking the coolant level every time I start rolling and of course the temp gauge will tell me if I have any problems. Not sure if I am underestimating any risks...

My insurance is through progressive and they just dropped me (and then sent me a customer satisfaction survey - not a great plan!) but I read the document and they are giving me a month's notice so I will be legal for this trip that I've been planning for a year!

Yesterday I was pretty sure it that the trip wasn't going to happen but it looks like we just might squeak it in.

you were on a commercial policy and they dropped you? or an RV policy?

im glad jumping the sensor worked.. it very well may be that sensor is simply a switch and not a resistance sensor.. if it was a resistance sensor i wouldve thought it throws a short-code and not work.. since you didnt get a short code you may be fine to just leave it as is jumpered..

I was on an rv policy. Their cancellation note actually says to contact them about a commercial policy.

I am just very relieved that they are covering me through this trip.

It's just a switch, and I'd recommend replacing it. Main reason is that if you blow a hose, you probably won't notice that on a temp gauge.

true enough.. ive always replaced them on the cars that had them.. (cadillascs with aluminum engines)..

on a diesel getting hot is FAR WORSE than running a standard gas motor hot... and they can get hot QUICK if you are pulling hard and lose coolant...

im building an alarm system for mine to notify me quickly of coolant level,temp, oil press, oil temp, trans temp.. the cooling systems on some of these busses seem so small anyway...

Ok, I jumped the sensor and the check engine light turned off. But then when I drive, the RPMs still seem limited to 2000 but the check engine light is off and there seems to be a lot more power. Is there any chance that this is normal? I can drive it a lot faster but it still wouldn't be fun on the highway.

I was literally on my way to my first highway run and didn't feel comfortable getting on the on ramp. I know I'm crazy but I'm supposed to start my trip tomorrow.

When I run the idle diagnostics, I get a constant flash instead of any particular flash code. Again, there is no check engine light. Any ideas?

Getting a little desperate.

have you tried battery resetting the Computer since you jumped the switch? it IS possible that it was limited to 2000 RPM but sounds awfully low for that engine even with an overdrive automatic.. have you actually tried to run the bus up to 55 yet? say on a 2 lane country state route where you domt have an entrance ramp and large amounts of traffic to contend with?

I am on a bunch of nice straight country roads. I have gotten it to 65 but never over 2000 rpm. I pulled the cable from the battery and put it back in the engine diagnostics is still just flashing and beeping. Is this normal when the check engine light is off?

I haven't tried driving it again yet.

Am I correct in assuming that if the check engine light is not on, then the ECM should not be limiting the RPMs unless it was programmed with a limit?
