2005 Civic Ex Special, P2646, 4k Rev limiter
Hello,
I have looked around for a while online trying to find some more information on this problem, and have seen this site pop up a bunch. Here is the complete list of events...
P2647 = GENERIC( 'A' Rocker Arm Actuator System Stuck on Bank 1), HONDA(Rocker Arm Oil Pressure Switch Circuit High Voltage)
P2646 = GENERIC ( 'A' Rocker Arm Actuator System Performance / Stuck Off Bank 1), HONDA(Rocker Arm Oil Pressure Switch Circuit Low Voltage)
Any thoughts/suggestions? I am new to cars, and really didn't know anything at all about them until March.
Thanks
I have looked around for a while online trying to find some more information on this problem, and have seen this site pop up a bunch. Here is the complete list of events...
- March 2017: Broken steering column rack and pinion bolt, along with P2647(https://www.autocodes.com/p2647_honda.html) CEL code
- Repaired, and CEL dissapeared
- April 2017: Car overheated, and I kept driving for a while, refilling coolant, etc.
- May 2017: Finally took car in, and diagnosed a broken head gasket
- Repaired, and on return of the car P2646 (https://www.autocodes.com/p2646_honda.html) CEL code appears on revving to ~4k rpm, with stuttering and back kick from the engine
- May 2017: P2646 code remained, so I took back to mechanic and he said that he overfilled the oil. He drained it and refilled, cleared the codes, but P2646 CEL code comes back at 4k rpm.
- P2646 shows in BOTH pending and stored codes
- Once hitting 4k rpm, Car stutters and shakes and will not allow any acceleration or going past 4k rpm
