Fault Code #33

[james1300]

It started today while on an EZ ride. First just a stumble while accelerating out of corners. Felt like a fuel problem. 57K miles on bike.

But with a half tank of fuel that didnt make sense.

I kept riding then the stumble came back. Between 3-6,000 RPM. Still felt like fuel.

Then the yellow CK engine light came on.

I pulled in the clutch and shut the engine off and coasted to a stop.

Let it set until the group returned to fetch me.

Tried to start it and it fired right up no yellow engine light.

I limped back to the main road.(rode EZ) Just before I got to the main road the bike dropped 2 cylinders and the yellow light came back on.

This time with a #33 fault code displayed.

Left the bike on the road and got a ride with MCRIDER007 (Thanks Steve)!

Got home and checked the Yamaha repair manual. Fault code 33 is ignition.

Got my truck and tie-downs and fetched the bike.

Thanks 'Kawpatty' for helping load a FJR with a half tank of fuel into my truck!

Checked the ignition power leads to the coil prior to loading the bike.

I was hopeing to find a loose lead coming off the ignition coil. Nope not going to be an EZ fix.

I started and moved the bike to load it. "When I started the bike it ran on all four cylinders for a moment then dropped two cylinders.

(The Yellow warning light and fault code stayed on.)

I'm hopeing its a ignition coil.

The bikes in the garage still tied into the truck.

I don't have a way to 'bench load test' the coil at the house.(That I know of)

I'm thinking I should take it to Desert Valley Powersports Tuesday (Home of FJR Goodies.com)

Trouble is I'm supposed to leave for a riding vacation in 10 days.

Suggestions??

Using Google fault code 33 site:fjrforum.com led me to the thread that's in the link. It has a list of all the codes.....

It took me longer to type this response than it did to look it up.....

Check all wire connections (hint: multi-pin connectors) before assuming it's hard parts. If not...it looks like you'll be late leaving on vacation. Sorry!

Thank you for the Link.

Hey I did some looking and code 33 is supposed to be an open circuit detected primary wire of the ignition coil

(#1,4)

Also it says to check, for an open or short circuit in the wiring harness, a malfunction in the ignition coil, malfunction in the ECU, or Malfunction in a component of ignition cutoff circuit system.

Hope this helps....

I'm still betting on a loose or corroded connector....

Number One rule in chasing electrical problems...try the easiest things first!

Good luck!

Ya know, I just had the lower fairings off and had a time getting the R/H side back on.

I'll pull it again and, check the wire connections on the 'lower coil' tomorrow.

Which coil is the (1) and (4) coil? The upper or, lower?

I beliewe it is the one on the Right Side (Lower) with the Arrows...the same area where you had a hard time.

Hope this is it...

Also pay attention that those coil connectors are not bent too close to each other as they can short out.

FOUND IT! I WILL make the Rally!

Power lead (orange) on 'LOWER' coil was loose creating a stumble and causing a 'Fault Code'. Removed lower r/h side of fairing this morning and found the problem. Squished the spade connecter to get a tighter fit and reinstalled it.

Test rides to follow!

Great job. As one who also enjoys riding my FJR to BMW rally's, good you can go. I was in Bloomsburg a few weeks ago for the National BMW rally, it was a blast, hot as hell, but the people are great and you see some fantastic bikes.

Enjoy and glad you got it fixed.
