F1 light map sensor - clean the 5 way connector
« on: December 12, 2013, 11:46:10 AM »
Well for some time I have had the F light come on and give the fault code for the map sensor.  I would clear the error code and be on my way, a month later it might pop up again.  Research had shown that there was a good chance it may have been an issue with the 5 way connector under the air filter compartment.  Today I attacked the bike.  There is a link with photos (not mine) to show where this connector actually is:
http://koczarski.com/ST1300/FI%20Error/MAPerror.htm

and a photo of the gunk that came out of mine


well worth the effort to dig in there and clean it out.  the gunk was only in one part which blocked two hoses.

It was raining this afternoon, so, inspired by TJ's success I decided to bite the proverbial bullet.  I'd had the FI light event a while back, and the ST has seemed to run a bit ratty on the highway lately- just the suggestion of surging.
I hate pulling it all to bits slightly less than putting it all together, but today was worse than usual.  You know "the last xx" syndrome?  The last screw that won't budge, for example?  I had 22 of the 23 screws out, but the last one on the tube that bolts to the throttle body refused to budge.  The Phillips head was beginning to suffer, so I brought out the heavy hitter which also failed to budge it.  I only had the "drill it out" option left and lost an hour to that, damaging the plastic in the effort.  Then it was the dive into the bowels of the throttle bodies to removed the 5 way connector.  Mine was completely clean!  All that pain for nothing!  I ran out of daylight and interest and put the cover over the disemboweled bike.  At this stage the damaged plastic component is in the vice while the JBWeld sets- the product claims to stick PVC and other plastics.  I need a stop gap while I source a new part.  Guess I'll need a new screw too.  It has a 7mm shoulder to accommodate the plastic fitting.  Probably not one on the local Honda shop's shelf.

Not happy, Jan.  About the only plus from the exercise was the opportunity to clean the bugs out of the air filter.  Didn't need to remove the last 16 screws to get to that!

Further confirmation that my fourth career won't be any sort of mechanic!

I'll have to have a look at this while I'm doing the Cruise control this weekend. Very timely.

Bit of a bugger Biggles. At least you know that is not the issue, normal fault finding process  >:()

Good opportunity Malcolm, the cruise control fits in nicely there.

F1 light map sensor?


It's a common error.  The light is actually an FI light, pertaining to the Fuel Injector system.
Perhaps a subconscious association with racing cars?

Great description  ++  The positioning of the 5 way seems to be part of the problem, as deposits can collect over time.  Well worth checking if the bike is apart for any other maintenance or farkles.

Great pix Abe.
Your pic #2 is worth noting.  I struggled to disconnect the 5 ways connector reaching around and under those leads.
Your point about marking leads is a good one.  A method I've used is the brush that comes with white correcting fluid.  There are also white correcting pens.  The mark isn't permanent, but it's durable enough to complete the job.

Seems like 50K or more is where this happens, so could be something to do just in case.

You are correct again Pockey, and thank you.  But did you notice that I did not mention (yet) what was hanging on my bike aerial drying :think1 :think1, just saying. (have photo, just saying)

I plan to clean my bike's "5 way" next week (or two) as Saaz said around 50K seems to be the go.

 Tank, Airfilter cover (top), Air filter, Trumpets, Air filter cover (bottom) and disconnect a few sensors to make a little more room........mark everything before disconecting unless you have a photographic memory.......take you a hour or two, follow Abe's instructions and you wont have a issue.   ;-*

Well I planned to carry this maintenance out this weekend.  So on the way home on Friday I stopped at a Tobacconists and bought Pipe Cleaners ($2.50)


I was getting the FI light flashing twice, not idling when cold, smelling of un-burnt fuel when running rough with the FI light permanently on and poor furl economy.  This usually occurred when the ambient temperature was below 25 °C.

When I took off the air filter cover I discovered someone had marked all the trumpets for me.  :grin




I'm glad I performed this maintenance because when I lifted the K&N air filter out I found Sand and Gravel under the filter.



Like Biggles, I had a drama with the last screw being stubborn, but before I put to much strain on it, I remembered and old trick of hitting the handle of the screw driver to "crack" the bind. Viola, one loosened screw.
Before I removed the Fuel injection connectors and the MAP hose connectors, I marked the rails so I could remember which one was which.





After I got the MAP hoses out, I was uncertain that the pipe cleaners I had bought would fit, and then had the idea of using a round Toothpick.  All most a perfect fist like a piston in a cylinder and this is what came out.  The "wax" is really carbonised thickened oil.




After I got that out, I gave the pipe cleaner a go (dipped in Metho) and it cleaned the 5-way adapter out perfectly.


As I was pulling it all apart I was trying to work out a way of preventing this happening again.  I think because the 5-way is below the manifold connectors that the oil drains into the 5-way, so as I re-assembled it, I put the 5 way above the Fuel injector cables to Cylinder 1 and 2 like this.







Hopefully this will prevent it happening again as the hoses are a larger internal diameter.
The end result though, is a bike that starts first crank again!!!   :grin ++

"Oh so happy!!"  :runyay


Thanks to Chris, Abe and TJ for the solution.  Winter this year will be a pleasant experience.
Cheers,
Gary

My son and I did the "5ways"  today and it was as clean as a whistle. 

Also did the fuel filter (rubber gasket/2 banjo washers), fuel filter clean and no contaminates of any kind.

Bike has done 50647km.

The solution of some has been to relocate the 5 way connection to see if it solves the problem by removing the low point.  It would be interesting to see what factors lead to come doing it and others not.  Have to have  a look at a diagram of the fuel system to get some ideas (ie overfilling the tank and not heading off for a while, bikes parked in places where there is a greater temperature variation (Guyra vs Sydney) and such.

mine was stalling when cold - began intermittently and progressively got worse.
Followed these instructions and sure enough pushed a 5mm plug of crap out of the connector.
Thanks guys - Chris you're left one is safe:-)

A big thank you to Tim TDing​ for helping me with my bike,  was lots of fun getting into the throttle body's! We even discovered that there had been a rat in the bike and chewed some wiring which we repaired along the way, Teela​ keeping us watered and fed was awesome

the hoses where cleaner than expected, but the FI light has gone away, and we got in and gave everything a clean up and the bike is better for it
