I curently have 01 accord in our shop with a bit of an issue. We just did a clutch on it. It was easier for us to drop the subframe. After we put the new clutch in and bolted the subframe back up and hooked the harness back together we started the car and the fan kicked on without any thing being on in the dash. also it through a code for vtec system failure p1259. Anyway we took the car out for a drive and the car has a 4k cut off it will not rev past 4 grand. Any ideas on what the problem might be? I hooked up gall grounds but maybe im missing somthing? any imput would be great!!!

 

I think it's the grounds but I have checked them twice any ideas???

 

Its in limp mode, are there any CELs?

Double check your wiring and ECU, is the ECU correct for your wire harness/motor?

 

Well if limp mode cuts in at 4k then yes and yes there is a cel only one code though p1259 vtec system failure. ecu was never unpluged from the body just did a clutch not a swap
