Engines Volvo penta Tamd 122 P-B ,port engine when turn on ignition alarm sounds plus warning light engine high
temp stays on
This has been going on for some time, switch ignition on and off couple of times and goes off, now on constant

Also getting fault code 9+9 = control module memory

Checked and cleaned all conections to edc wiring harness with electrical contact cleaner, changed over engine electronic

Unit, also edc engine temperature sender, cleared fault codes ,fault still there,

Would calibrating controls help, both engines start and run

This ones got me beat thanks for any advice.

I'm guessing could be the ECU anyone no of if these can be tested
 
What generation edc is this?

I ask as mine is evc a and does not show fault codes but just flashes, pauses for a moment and does it again. You say code 9,9 and I have a feeling that is the number of flashes mine makes between breaks - so it may not be a code at all.

I have exhaust temp alarms on mine. They sometimes go off and will also sound if the wire comes off. Is it defiantly engine temp ?

Boat is year 2000 so guess Ist generation EDC, flashing 9+9 book is stating control module memory, when all ok it flashes 1+1, we have exhaust temp alarms def not them, engine overheat light is permanently on
 
We'll be back after Easter, can't get rid of us that easy. It's been very handy just to be able to nip down though.
Just a thought, I had a similar issue which seemed to be altered when shore power was disconnected
 
All back together , run engines with alarm going, shut down cleared faults again restarted engines alarm off, switched off

engines left awhile turned back on ignition alarm back on , turned ignition key off and on alarm goes off, run up engines all

good , will check again tomorrow ,

Thanks for all replys

You have faults in both edc loom and engine loom , the engine loom is old school through 16 pin plug .
Edc fault is through edc loom , sounds like there is a resistance imbalance.
The common denominator is the engine earth system, I’d be looking for bad connections, I’d start at the alternator negative terminal then the starter motor , look in black box, there could be the edc loom negative connection, possibly the pop fuse if you have one.

If it runs it’s very doubtful it’s the edc control unit so that’s good.
122P getting on a bit so I’d def be looking for bad connection even a frayed connector if your getting the overheat alarm when cold, take both terminals off the sender.

Do you get high temp fault code on edc, has engine full power, if so it’s not edc temp sender , remember the dash gauge sender isn’t the edc water temp sender , it’s early generation which in effect is two systems hence the two looms.

Hi Paul engine runs fine ,no restriction of power, after cleaning connectors to EDC modules ,fuse box and control unit,fault code 9+9 will clear and alarm stops,leave for a day and it's back, I had trouble with starting this engine, on checking battery's they were down so renewed them, think the problem was an Earth conection as after disconnecting and cleaning cables ok now, if I turn the key off and back on all ok , will have another check re earth cables
Thanks for reply appreciate the advice you have given me, think I need to book you to have a look before the start of the season ,

VolvoPaul, I have some questions and would like to see if you could possible lend a hand. I have read some of your stuff and can understand most of what you are saying. I would like to start by saying that I have a TAMD 122P and yesterday I went out to go for a cruise and left the dock and noticed that only half of the active station had transferred to the upper helm. I put it on the dock and tried most of the day to figure it out. here is a List if things that I had happen.

Port side would go into gear
Starboard side would not go into gear.
It appeared half of the active station was dead.
Pressed the active station button again and all I got was the relay clicking about 6 to 8 times. Went to the lower helm to reset the code on the port side 6.4" Fault in MS Unit" and the code on the starboard side was 6.5 "Minor Fault in MS Unit" no mater what I did, or do I can not get the 6.4 code to clear?
after looking and everything and trying to do a throttle calibration, which failed. Now I have the lower active station light blinking rapidly and wont stop. the starboard side seems that its calibration worked but the port side will not, as I can not clear the code. once I did the Cal. I tried to start the motors and had no issue with the port but the Starboard would only maybe a 1/4 revolution and would not start. at one point the active station on the flybridge switch sides. at first it was the port side that wouldn't would and after doing what ever I did it went to the Starboard side working. Even on the lower helm it was only work half. hope that makes sense. please let me know if you have any idea's thank you for the help. Thanks again.

You need to read the blink code then report back , code might clear when you turn key to stop position.
what model of boat is it ?
 
The codes are the ones I listed after the 6.4 and 6.5 in parentheses above. my boat is a 52' Viking Princess. I'm thinking its a plug either loose of corroded, but just thought I would ask to see if you had come across the codes not clearing at all. Thanks again for your time.
 
Unable to help with your problem, ours turned out to be the batteries, having tested them they seemed ok but apparently one wasn't, changed all 6no and no more problems, alarm was caused by exhaust sensor correctly diagnosed by jrudge,
The flashing simble on dash through me, thought it was temp as indicated in Volvo book, turns out to be exhaust alarms.

mine 50% of the time as the warning triangle and 25% of the time insists that coolant is low.

This has been going on since April 2018 when I bought it and I suspect will continue forever. It runs fine!

I have done the clean connectors thing half heartedly but to find and clean them all on a s58 including all helm units is probably a days job and risks breaking more than it solves.

Fortunately I have gereration a which I think ( only think ) does not have limp mode.

It does make me feel for people with IPS drives. I keep reading about resolvers ( whatever they are) breaking and putting the boat into limp. I am all for technology but electrics and sea water coupled with infrequent use really dont make the best of friends.

HI! did you solve the problem? I have a problem similar to yours, code 6.4, the starboard engine while I'm sailing goes into neutral after two hours and I get error 6.4. Do you think it's the control unit or is it the wiring? my boat is a princess 52 fly like yours
