Has anyone had a problem with the ecu shorting out the VTEC?
03 accord lx l4

 

Never heard of that.... what exactly is the car doing?

 

every time i clear the codes the vtech works fine and after 5min's of driving it comes' right back and it is the same code p2646. I replaced the switch had my buddy check it and thats what he recomended, i went back and he said I don't know really what else it could be. ecm??? so thats why i'm asking anyone heard of that.

 

Didn't you already start a thread about this problem?

Starting multiple threads will only lead to scattered ideas to help you with the problem, and confusion among the folks trying to help.

 

Check for oil pressure switch with a open or short circuit..
You more than likely have a failed VTEC pressure switch..
Also check your oil level and pressure...

It's also possible that your valves are a ways out of adjustment and need to be brought back to within tolerances... Also, you said the passage was clean but I believe there is a filter in there that may be plugged as well...

Yes I did have a thread going on this problem and didn't get a response on the subject so i started a new thread based on the ecm not the switch. Scattered Ideas are always possible even if there was one thread started.Sorry for not knowing the proper etiquette for threading my problem hondadude, just very frustrated when you can't figure something so simple as what sir_nasty suggested. Thanks SIR_NASTY cleaning the stainer on the vtec has worked so far has not sent out dtc yet. crossed fingers and toe's that this is it.
