Engine warning light Evinrude Ficht RAM 2002/2003

[Andrik]

I have bought what should be a Evinrude 115 Ficht RAM complete powerhead with all components. It must be a 2002 or newer, since it has a newer oil lift pump than the pre 2002. When I tried to fire the enginge up today, it shut down after some attempts, and the third warning light on the system check was lit. I guess that is the engine warning light.

When using Evinrude diagnostics, it tells me that the EMM is a 90hp. The current engine faults are:
code 47 - Air temperature Sensor Circuit Fault
code 48 Air temperature BELOW range.

It is cold here today, just +2 C. I tried to chang to another air temperature sensor, but the motor shuts down after a couple of seconds, and the engine warning light lits.

Doeas anyone have any suggestion for a solution?

I wonder if there could be a wrong EMM on the motor? Can anyone tell me if the EMM is pre 2002 or not out of the data below? The data from Evinrude diagnostics is:
Serial no 4963105
EMM date code 23JZ
Map soft version 3030174
Map soft rev 29564
I also attached a picture with all the info I got in Evinrude Diagnostics

something wrong for certain EMM should reflect reality 115hp
next thing is to fix the sensor fault

check your injector tags to see if they match the EMM log if not EMM was substitured or eprogrammed for some reason.

Unfortunately there isn't much info to the level of detail you need unless a FICHT expert shows up here
but.. you can download the service manual for the 2002-2006 FICHT from this site and read up on it. See sensor testing section

EMM rebuilding service, thumbs up!

Hope this is not repetitive, and wanted to relate my experience in having my G1 E-TEC 90 EMM rebuilt. My understanding was that there was no one in USA doing this, so late in 2023 looked into a company that did, Hardware Care located in The Netherlands. Starting at their webside, you can get an...

Air Temp Sensor Fault

I purchased twin 200 E-Tec small blocks in Nov. 2015. I've been out 7 times since the install. The Air Temp Sensor alarm (stbd eng) has sounded on 5 different dates prior to returning to the dealer for repairs of this alarm. The alarm sounds when idling (trolling). On some days it has sounded as...

Thanks, the seller told me that the engine was in good condition, and that the reason it was dismounted was because the lower unit was damaged due to running aground. He said it had good compression.

I have two other 115 EMM's without any fault codes, but I am unsure if they are pre 2002 or not...

I have replaced one injector and reprogammed it. I will check the data on the other ones, as you say.
And test the air intake sensor/circuit

 

[Andrik]

Update:
None of the other injectors was programmed in the EMM... I programmed them, and then the motor fired up easily
The compression is good, 123-123-132-132 psi
Still get the same error codes and the check engine alarm
EV Dialog tells me to check the blue/purple wires and ground

TESTING:
ATS
2,2 ohm resistance on the purple/blue wire to the ats
Sensor 12,2 ohm (-2 C temperature)
3 volts when key turned on

WTS
1,67 ohm water temperature sensor
Sensor 12,67 ohm (-2 C temperature)
2,97 volt when key turned on

TPS
5 volt when key turned on

Crank poristion sensor
0 volt !!??

see manual on 20002-6 FICHT sect 3.41.. +
my understanding is that he CPS is a AC signal generator and would normally be without DC voltage . it has OHMS resistance to check and if your engine does start.... it is working otherwise the EMM would interrupt the start process.

as to ats resistance ???? see code47 info in the manual

 

[Andrik]

SOLVED
The resistance testing was wrong, the sensor was in working and have the right values.
The problem making the code 47 and code 48 was the black cable to the air temperature sensor. I had not tested the voltage between the black and purple/blue wire, but between ground and the purple/blue wire. There was no connection to ground on the black wire, so I made a bypass wire between ground and the black wire at the ATS connector, and then the active faults disappeared. Thanks for the help, Crosbyman.

Glad you found it.... hopefully your on your way fishing

thanks for your feedback yet the mystery..... why was black ground missing but it is accademic now.

I'm unforunately still not out fishing...

I decided to have a last test before boating to see that the water is passing through the motor. It's -7C outside, and I feared frozen hoses . There was no water coming out as I feared. I used warm water, filled warm water up to the waterintake for a couple of hours. Still no water coming out, and then I got a new check alarm:
The fault reading says that this occured:

Code 43, Engine temp above range
Code 22 Water temp switch closed
Code 27 12 V circuit above range

Could there be a connection between code 22 and 27? That the high temperature might put additional stress on the electrical system, leading to voltage irregularities?

Or could it be that I connected the black wire from the Air temp sensor just to ground, not to the black wire I suppose is connected with the EMM?

 

[Crosbyman]

you should not have frozen water if stored properly & vertically

check manual for code 22-27 do appropriate voltage readings with VOM on the 12 volt distribution .I doubt high temps influenced the alarm
code 43 may indicate a water problem..did it pump water ok before ??

just my humble opinion...
