Rep Power: 0 03 civic si - CEL code p1259 revs limited at 4k
Hey all
I was wondering if i can get some info/help with an issue. I was driving home tonight in my civic that i had bough 2 months prior. The CEL light kicks on on my way home while on cruise control. I pulled to a red light and when taking off, the car is rev limiting at 4000 rpm. I had also noticed that lately when giving it throttle it seems like it pukes and then takes off. Puking lasts all of 3/4 a second.
The car idles smoothly and it feels like the car isnt even on!
I pulled in the driveway and hooked up a pocket obd2 scanner and i get 1 code, p1259. I loosely checked Google for the issue and then went and checked the oil. It is full. I had to put half a quart in about 2 weeks ago. Something about VETEC
Anyone else have this issue? Insight or anything to add?
Thanks

1 - change your oil and filter, disconnect battery for half hour,
problem still there?
2 - remove vtech solenoid and clean it, reinstall it, disconnect battery for half hour
problem still there?
3 - replace vtech solenoid, disconnect battery for half hour

what involves VTEC:
1) Oil pressure, so low oil is usually most frequent
2) Electrical - solenoid activation
3) Mechanical - clogged passages or solenoid stuck
4) someone disassembled and dropped one of the pins on rocker arms.

can number 4 be ruled out by listening to the engine run? it makes no noises at all. im picturing in my head clanking or something because of the pin?
how to test electrical if oil change doesnt work?
thanks

Did you take rocker arms off and disassemble? If not, no point in asking about pin... as mentioned...

That could only happened if you removed the arms for, say, changing the camshaft, like me and others had done. If not the case, it should not happen (remember, like you, I am looking at a computer screen, no way for me to know, so I put it there as possibility.
Any luck on the other item WE posted? (Not only the ones I posted, I mean )
And believe us, the rodent is not a joke...
