Hey guys, I'm getting code 2647 today for Rocker Arm Actuator Stuck ON. I had gotten this code before, and it went off on its own the same day so I didn't replace anything. But today it came back on, and my car started acting like it was hitting the rev limiter when I was pulling back into work.

I've read on some other forums that it's not difficult to repair, but those were on K24 CRV/Accord engines. Does anyone know where this sensor is on the L15 head in an 08 Fit base?

 

Nevermind, I found this thread after doing more Google searching.

Gimme posted that its on the front of the head to the right. I'll go back out to my car after work and see if I can find it and hopefully she makes it home.

 

Figured it out. CEL is off now. I'll do a full DIY on it tomorrow with pics (since the other threads had advice, but not a full DIY per se).

 

I, for one, will be looking forward to your follow-up.

 

Thanks!!
On old Prelude the rocker arm actuator got stuck due to the plugged oil screen under the solenoid valve. We "fixed" it by poking a hole in it with a screwdriver

 

Sorry no pics, write up yet. I've been hella busy with work projects and otherwise.

But the EXACT location of the sensor is between the intake runners and metal breather tube on the on the air intake. Its partially hidden by the bottom right corner of the plastic engine cover (I removed mine to better get my fat hand down to it).



Google pic for reference.

 

What a beautiful pic of the engine............matches my engine exactly ...............sure wish you'd indicated WTF exactly this thing is...............sigh
