fixnproblems I have a no start issue with a 14 code. 7FGU30 4Y ECS on LP. I found the electric govener behind the right step. One has 5 volts one is ground the other is around 5 volts. If I turn it down the volts will drop to 4.4 volts then goes to 0 but I still can turn it down. Thinking that this part is bad.......

Thanks for all your help. I'm usually the one helping people with these issues and feels good to be helped my self.
I have zero support (my last Toyota contact retired;(.
It is lp. And I have came across something on this forum that the 14 flashes is "idle stuck at 750rpm "
This makes sense for the symptoms as Engine dies under any load IF LEFT AT IDLE.
Truck starts and revs up good otherwise Just seams like nothing communicating with electronic throttle body for increased throttle automatically under load.
I wasn't sure if it receives a vacuum signal or rpm signal to determine load conditions.
Assuming it's tach signal from distributer.
And when the dealer told me "were not sure what the 14 code is" I told them politely well if A Toyota dealer doesn't know who does? you guys should have factory support"
I think there just being lazy.
I deal with aerial lift equipment (JLG, Genie ect. Factory support few times a week and have yet to run into dead end like this dealer Seams to be with my cust. Lift.
I otherized them to replace the throttle pot a few weeks ago so hopefully that will solve my issues. I am skeptical though as they are just guessing and have not tested the pot to determine if it's bad,, very frustrating.

Also forgot to mention, two months is a long time to have a lift down, they should have had this machine diagnosed already, If they are an actual Toyota certified dealer they have access to contact the technical support team at the manufacturing plant located in Indiana.

Hey there, Sorry I don't have a flow chart, is the lift a gasoline model or lp? If the machine is an lp truck i believe i have given you the wrong code. I apologize. If the symbol you see flashing with piston with a rotation symbol is the one that you are counting then i can help you. The 14 code is the code that needs to be focused on, that truck has a idle pot located under the right foot step located on the electronic governor, code 14 means Idle setting variable resistor signal open or shorted, the resistor has three wires to it. one will be a 5 volts the other a ecm ground then a return signal back to the electronic governor. Before replacing any parts i would connect a tachometer gauge and check the idle, Its suppose to be 750 rpm when engine is warm, i would also check base timing, it should be 5*btdc, If idle is off rotate the the pot very little to the desired rpm, then retest, i have had a couple of those models give me similar symptoms due to the pot moving because the vibration. The idle pot will have a slit in the end of it that you can adjust using a flat head screw driver. I hope this helps.

Thanks Fixnproblems!
I'm still dealing with this problem, Love to have a flow chart/trouble shooting guide to address this issue.
I've Actually took it to locale Toyota dealer and they've had it almost two months. They "think that the throttle pot is bad. So I've oked them to order and replace the pot. Fingers crossed.

13 flashes =Engine speed signal system
No. 2 not detected. While starter was turned from ON to OFF,
engine speed signal not input.


14 flashes = Ignition signal system. While starter was ON, engine ignition signal
not input.

Anyone?
