Joey Mack Posted December 11, 2022 Share Posted December 11, 2022 they are around $40.00,,, buy one... Install it into that plugged port on the oil filter pad, and take a true reading.. You need a ( 0-150 PSI ) oil filled gauge.. and a few small fittings to make it fit.. So for about $50.00,,,, You will have a very important tool... jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70850-2000-rd-690s-em7-300-starts-idles-then-shutdowns-along-with-non-working-guages/page/3/#findComment-517999 Share on other sites More sharing options...

htx-em7-2000 Posted December 28, 2022 Author Share Posted December 28, 2022 I have been shopping around for the Oil Pressure Sensor for MACK E7 64MT2115. My local MACK quotes me $200 out the door. But the links below have it for half the price and want to make sure they are MACK and not aftermarket. We really prefer to purchase a MACK sensor than an aftermarket.

Joey Mack Posted December 28, 2022 Share Posted December 28, 2022 I'm just curious.... Were you able to put a gauge on it to get a true oil pressure reading??

Joey Mack Posted December 31, 2022 Share Posted December 31, 2022 I didnt look back, but do you have any fault codes for oil pressure or coolant?

Joey Mack Posted December 31, 2022 Share Posted December 31, 2022 does the yellow lightning bolt come on too? Do you know how to get active codes using the cruise control?

Joey Mack Posted December 31, 2022 Share Posted December 31, 2022 so when you turn the key to the ;on; position, that bulb doesnt light up during the self test?

JoeH Posted January 1, 2023 Share Posted January 1, 2023 Change the bulb in your lightning bolt.... You could have engine codes that we can diagnose through that light if you can get it to work.... Key on, if the lightning bolt is in, you press and hold the cruise set/decel button until it goes out. Then count the flashes to get a 2 digit blink code. Press the set/decel again, if there's another code it'll spit it out too. Keep doing that til it starts repeating itself. Note that you perform this procedure with the cruise control "off". Engine can be running, or not. Tell us the blink code and we can stop guessing. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70850-2000-rd-690s-em7-300-starts-idles-then-shutdowns-along-with-non-working-guages/page/3/#findComment-519489 Share on other sites More sharing options...
Mackpro Posted January 1, 2023 Share Posted January 1, 2023 (edited) I don’t know if I mentioned this. Common problem with R series trucks with ETECH engines. The VECU ( vechicle electronic control unit) is mounted on the kick panel in front of the passenger seat down by the floor. The factory mounts it to the kick panel with the electrical connectors facing up . The windshields are bad about leaking and when the RH side does it drips right down onto the VECU. I have found the VECU’s to actually have water in them. This causes all kinds of crazy problems. Issues include having to crank engine 8-10 seconds before it will start, various guages not working, engine won’t die when you turn the key off until 8-10 seconds pass, low power/ sluggish response. This is because the high speed J-1939 data link is down and it’s running off the slow/low speed data link J-1587 so everything is responding super slow.

htx-em7-2000 Posted January 1, 2023 Author Share Posted January 1, 2023 Disconnected all the terminals and found that J3 terminal of the VECU when plugged back in 1 by 1 was responsible for the red shutdown light to function. Now when we turn the key the red shutdown light doesnt stop ringing. It lets us turn it on but shuts down seconds after. What did yall want us to do with VECU Quote Link to comment https://www.bigmacktrucks.com/topic/70850-2000-rd-690s-em7-300-starts-idles-then-shutdowns-along-with-non-working-guages/page/3/#findComment-519522 Share on other sites More sharing options...
Solution Joey Mack Posted January 1, 2023 Solution Share Posted January 1, 2023 (edited) one thing you can do is use your DVOM, and find a good ground on the cab, and check for continuity on all the pins in the J-3 plug.. that may point you towards a short to ground.. are you familiar with how to read the wire codes on the white wires? It is actually easy to do, and really helps when you are checking the wires at a distance from the VECU.. jojo Edited January 2, 2023 by Joey Mack poor sperring..

Mackpro Posted January 2, 2023 Share Posted January 2, 2023 (edited) Was the VECU with the connectors facing up or down? Was there any green or white corrosion in any of the 3 connectors of the VECU? Inspect the green and yellow twisted wires that go between the VECU and the ABS module beside it . The green and yellow wires are the high speed data links .

Popular Post htx-em7-2000 Posted January 10, 2023 Author Popular Post Share Posted January 10, 2023 Thank you all for your counsel. It resulted in being short to ground, as JoJo stated. That was outside the cabin, where the windshield wipers rest. We hired a technician that used one of those power probes and waved it around the wiring. And it would make a noise when it detected a short. Now we are going to buy our own power probe because we still have a faulty temperature gauge. Again a sincere appreciation for yalls time, attention, and knowledge. 1 2 Quote Link to comment https://www.bigmacktrucks.com/topic/70850-2000-rd-690s-em7-300-starts-idles-then-shutdowns-along-with-non-working-guages/page/3/#findComment-520813 Share on other sites More sharing options...
