Can anyone please help me, 2016 Mack Granite with MP7 engine. Step 9 states if you find any continuity in the connectors EA and EB well I have it between EA 61 and EA 44 and EA 61 to EA 36 and between EA 44 and EA 36…. Well aren’t they in the same circuit is why my meter is reading that
I can’t get the initialization to go through in this brand new VGT Actuator
I’m not getting any DTC codes and pedal position sensors are readying good voltage and going up to 100% but when she gets hot and on highway. Eventually you will press pedal all the way down and only get 35% engine load. She won’t accelerate. Can anyone help me where to start? I assume it’s going to be fuel related?
This truck is throwing a gang of DEF codes. Is the header bad? I unplugged one of the connectors going into the header and it gave me a DEF after treatment system pipe heater circuit voltage above normal code. The other connector I disconnected I assume didn’t show me anything because it already wasn’t reading some of the failed devices in the DEF HEADER like showing the PID DEF LEVEL AT 0% when it’s blatantly almost full. I unplugged that connector though and did have 2.5 volts on one and 12 volts on the other which I assume is my power and 5 volts reference.
When it gets hot she starts to high and low rev and kinda bog out. Can anyone give me any tips on where to start?
Anyone have any advice on where to start on this one? I know where the EGR is? Start checking the wires going to EGR Position SENSOR?
Someone please help. I own a power probe 4. There are functioning rear flood lights on rear of truck that turn off with a switch on the dash labeled “Rear Flood”. These two lights on back of cab have ground from the connector in the loom and like 0.34 volts on the power side on ignition. If I go to the connector on the end of the light and send 12 volts. I can turn on this closest light to me and that’s it. Any opinions? All fuses checked out. Wish I had a relay buddy to test relays faster
