msbulldog601 Posted March 27, 2021 Share Posted March 27, 2021 Hello Everyone, Posting to get some help with an issue I’m having with my 97 Ch613 E7427 Engine while driving the “engine shut down “ light started to come on for a few seconds then goes off... anyone know what I should be looking for ? Do you think I can pull codes? Thanks! Quote Link to comment https://www.bigmacktrucks.com/topic/66388-engine-shut-down-come-on-goes-back/ Share on other sites More sharing options...
tjc transport Posted March 27, 2021 Share Posted March 27, 2021 first thing i would do is check coolant level. there is a low coolant switch that will turn on the shut down light. 1 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

Coolant level is fine reservoir is topped off... where would the coolant level switch be located?

Joey Mack Posted March 27, 2021 Share Posted March 27, 2021 Is the injection pump, electric? if so there, is a timing sensor, one at the fly wheel on the left side at around 10 O'Clock. there is coolant sensors at the rear of the water manifold, yes... definatly check the coolant sensor in the radiator, or the tank on the left firewall. is there an oil pressure sensor in the oil filter pad? I think thats all of them. Jojo 1 Quote Link to comment https://www.bigmacktrucks.com/topic/66388-engine-shut-down-come-on-goes-back/#findComment-471578 Share on other sites More sharing options...
theakerstwo Posted March 27, 2021 Share Posted March 27, 2021 On the truck i have which is a VMAC 2 it for two years would miss or mis fire or sound like a back fire maybe on one cylinder and shake the truck good.I never saw a light come or a code come up.I would do this maybe once a week but about two weeks ago my voltmeter begine to drop voltage.I put a alternator on from one of the other truck but still low voltage.Then i started to check the alt wires and the ground below the starter with the 5/8 bolt on the wires to the block look a bit loose so i remove bolt and cleaned ever thing and now the voltage is up and also no mis fire sound.That been three weeks ago so i think the engine harness grounds to the block there. 2 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/66388-engine-shut-down-come-on-goes-back/#findComment-471579 Share on other sites More sharing options...
fjh Posted March 28, 2021 Share Posted March 28, 2021 The red shut down is set to come on with the 3 sensors Joey mentioned those three can trigger a shut down you have a minute to decide! How ever we used to disable low water shut down as it can be a PIA ! the light will still appear but the no action was taken to shut down if disabled! check the wiring over near the oil cooler the clamps tend to rub the wires there ! be sure your not over heating! Good advice by Glen there too Cover the bases! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/66388-engine-shut-down-come-on-goes-back/#findComment-471623 Share on other sites More sharing options...
theakerstwo Posted March 28, 2021 Share Posted March 28, 2021 About ever 6 months i have to clean my low coolant sensor or it will think its low on coolant.I use steel wool and wipe the tip clean and all is well.

Yes there is a oil pressure sensor on top of the oil filter pad. Should I just unplug the oil filter sensor Drive it and see will it come on? The “shutdown light “ only comes when the engine heats up.

Joey Mack Posted March 29, 2021 Share Posted March 29, 2021 yes, always from the "Big seat".... You can try that with the sensor, the engine will probably shut off after 10 seconds with the sensor unplugged. Well oil thins when its hot and pressure does drop... so, maybe a bad sensor, if you know the oil pressure is good. your gauge should be hydraulic. there will be A #4 hose coming off the top of the filter pad, and going through the firewall to the gauge.. jojo 1 Quote Link to comment https://www.bigmacktrucks.com/topic/66388-engine-shut-down-come-on-goes-back/#findComment-471701 Share on other sites More sharing options...
msbulldog601 Posted March 30, 2021 Author Share Posted March 30, 2021 I started the truck up today after replacing fuel filters... rode the truck empty for about 45mins the “shutdown light” didn’t come on one time I drove the truck hard getting the temperature up to see would it come on and it didn’t. This was right before dark so it’s not as hot like the daytime. I have a picture of the injector pump should I replace this sensor since it’s a leak on it? The canister for my centrifugal filter is dented so it’s hitting the inside as it spins I wonder would that trigger the light and mess with oil pressure?

Joey Mack Posted March 30, 2021 Share Posted March 30, 2021 (edited) Yes clean the T.E.M. sensor... wash the mess off before you remove it.. Don't "F" around.... Do a good job! Pay attention to the keyway on the sensor. The dented centrimax housing looks to be minor, when you shut the engine you should be able to hear the filter spin down, or have someone shut the truck off and you can feel it spin down, or... just change the housing...It wont effect oil pressure because it will just pump oil through it..

msbulldog601 Posted April 1, 2021 Author Share Posted April 1, 2021 Okay I’m dreading going to the Mack dealer I know it’s going to cost me... I have one more thing... I ran the truck today until the “shut down” light came on pulled over at idle my oil psi is about 25psi so I accelerated a little to push it to 30psi and the light went off I put truck in gear go on interstate it came back on about a mile down the road I went back to the yard park accelerated push the oil psi to 30 psi again the light shut off. What do you all think of this? Quote Link to comment https://www.bigmacktrucks.com/topic/66388-engine-shut-down-come-on-goes-back/#findComment-471869 Share on other sites More sharing options...
Joey Mack Posted April 1, 2021 Share Posted April 1, 2021 seems odd to me.. if your on the highway the oil pressure should go up with higher engine speeds. I'm scratching my head.... just for kicks, the round duetch connector for the governor housing..... did you check the wires to see if they are loose or chafed sometimes the pins will move inside the plug and make a poor connection. .. jojo Quote Link to comment https://www.bigmacktrucks.com/topic/66388-engine-shut-down-come-on-goes-back/#findComment-471888 Share on other sites More sharing options...

Only connector I can remember of like that is the one to the injector pump... where would this governor housing be located?

Tmac11 Posted August 4, 2022 Share Posted August 4, 2022 The same exact just happened to me check engine light came on and while driving idle cool down message came up and truck shut off light Quote Link to comment https://www.bigmacktrucks.com/topic/66388-engine-shut-down-come-on-goes-back/#findComment-505288 Share on other sites More sharing options...
Joey Mack Posted August 4, 2022 Share Posted August 4, 2022 do you have an injection pump with the electric governor housing? Quote Link to comment https://www.bigmacktrucks.com/topic/66388-engine-shut-down-come-on-goes-back/#findComment-505310 Share on other sites More sharing options...
Chapter One Posted August 31, 2022 Share Posted August 31, 2022 Hey. I have a 2002 Mack Rd and the last 8 months about the shut down light just stays on. Of course all fluid has been checked and all sensors have been replaced. It will even do it just when I turn the key on in the morning before even starting it. The buzz sound is annoying but it never shuts the truck off. Had a few mechanics look and can’t figure it out. Might need to try to replace the cluster but for now I’m just rolling.

Joey Mack Posted August 31, 2022 Share Posted August 31, 2022 Can you hook a scanner to it to see what codes it has? You say the buzzer is goin off all the time? Is oil pressure above 10 PSI? I wouldn't throw parts at it before looking for a faulty sensor, or bad wires,. When you turn the key on do all the warning lights do a self check?
