Santos Posted August 27 Share Posted August 27 (edited) Hi yall I hope I am creating the right post for my question. I’m new here. Anyways. I have a 1997 ch600. I’m having issue with the engine shutdown light. Lately it’s been happening now that it’s hot outside and only loaded. The light will turn on and after a couple of minutes of driving, the truck will turn off. At first the oil pressure would drop at truck would shut down. Pressure no longer drops. Water temp slightly increases but never in the red. I had ONLY the electric malfunction light on when I turned the key after it shutdown but hasn’t happened again. We have changed the alternator and coolant sensor so far. Next is the oil pressure sensor. Any leads are appreciated!

mechohaulic Posted August 27 Share Posted August 27 "97 is way to new for me , based on the knowledge BMT members post and old mechanical thoughts; don't you get codes explaining the fault?? what are the gages reading.?? as noted - now that it's hot outside and loaded . temp going hot by gage?? fan kicking on ?? changed the sensor but what is actual engine doing?? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74500-engine-shutdown/#findComment-557664 Share on other sites More sharing options...
JoeH Posted August 27 Share Posted August 27 (edited) Are you low on coolant? Not sure about the 1997, but the E7 ETECH engines use 2 oil sensors, one for the dash gauge and the other for the EECU or VECU. You need to make sure you replace the one for computers if that's the cause of the shutdowns. I'm guessing this engine is vmac I or vmac ii, I don't think vmac III was rolled out yet. If by chance it's vmac III you should be able to pull blink codes out of the check engine light. Typically the engine shutdown light is controlled by low coolant level and low oil pressure. Possibly high water temp too. Edited August 27 by JoeH Quote Link to comment https://www.bigmacktrucks.com/topic/74500-engine-shutdown/#findComment-557680 Share on other sites More sharing options...

Joey Mack Posted August 27 Share Posted August 27 He has only 1 oil sensor and 1 live line to the gauge. There is a timing sensor in the flywheel housing, and a duetch plug on the injection pump.. i dont see where he states if its full mechanical, but i dought it is..

The Heinz Posted August 27 Share Posted August 27 I think a '97 would have an Econovance, correct? VMAC I or VMAC II depending on if it was upgraded. Quote Link to comment https://www.bigmacktrucks.com/topic/74500-engine-shutdown/#findComment-557688 Share on other sites More sharing options...

Try toppin up the coolant! it is likley set to trigger but not shut down ! As it warms the coolant expands! 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74500-engine-shutdown/#findComment-557695 Share on other sites More sharing options...
Santos Posted August 28 Author Share Posted August 28 To add, the truck technically doesn’t overheat. Water temp will go a bit over 180 but never in the red. At first The oil pressure would drop then shut down instantly but no longer does that. Now it just shuts off. We can’t get it scanned bc it only happens when I’m loaded. Idk what else to look for besides pressure sensor and oil pressure pump.

Joey Mack Posted August 28 Share Posted August 28 Don you have the electric gray colored plug at the injection pump? Quote Link to comment https://www.bigmacktrucks.com/topic/74500-engine-shutdown/#findComment-557743 Share on other sites More sharing options...
