The vtec solenoid on my honda crv leakes. what should i do

USA spec car in USA? not told
2.3L inline 4 banger.DOHC +VVT cam. 5sp, M/T
nor real name of the box told.
Vtec is honda name for VVT, valve variable timing, and is not a transmission part at all so is off topic if we want to do 1 at a time.
a wise idea that, leaks are your problem.as all are.
your post seem clueless, here, find a real shop and get it fixed?
vtech bad causes huge engine power loss, for sure stuck in idle mode. so lets end that here.
and talk the box, what box 5 speed is it
not told at all
honda says 5speed is a manual transmission M/T
the silly cable to it is bad.
end story, endless.
2 cables clutch release snapped i gear. makes it hard to shift if you do not move car bay hand to N./ (a trick to lean 2 man job) as all tow truck drivers know for 100 years.
shift cable bad. (or levers to it)
see this first photo , one can drop off links to that #8 part and shift the box by hand, sure can and if can the box end is good .
box means transmission box in whole.,, mech jargon.
all this is pure mechanics 101 problem shifting any M/T is.
photo 2 is lever #2 id and cable set 6
one if bad, looking only finds it as is 100% pure mechanical parts.
end to end. no brains no CPU or TCM brains here, just real gears and levers and flex steel cables that love to fail not lubed regular.

vtec oil pressure switch, but try changing the oil first, sounds crazy but but if sludge clogs switch from detecting oil pressure will cause the problem.

Why did you change all of those things if you were told it was the VTEC solenoid? Why not try that first? Read online to see if there is a method to clean the solenoid without replacing it. I'm not sure that the VTEC solenoid would cause such problems, but I suppose it's possible. The VTEC system uses oil pressure to change the follower on the cam lobes. It changes between profiles. So at higher RPM, it switches to a different cam profile that is more efficient at higher RPMs. Like having 2 cams in 1.

read only the honda books on P2xxx codes, its unique to honda.
VVT, variable valve timing (cam) magic is unhappy

P2649 Honda - VTEC Solenoid Valve Circuit High Voltage


Possible causes
- Check engine oil level and pressure
- Faulty VTEC Solenoid Valve
- VTEC Solenoid Valve harness is open or shorted
- VTEC Solenoid Valve circuit poor electrical connection

P1259 HONDA - VTEC System Malfunction
Possible causes- Low engine oil pressure or level
- Open or short circuit condition
- Faulty VTEC oil pressure switch
- Faulty VTEC solenoid
When is the code detected?The P1259 is set when there is a problem in the VTEC Oil Pressure Switch circuit or VTEC Solenoid Valve circuit

P2647 VTEC oil pressure switch circuit high. The letter P stands for power train.When a code P2647 comes in the shop VTEC oil pressure switch usually fixes the problem. In front of the vehicle on the right hand side there is a VTEC solenoid valve one one the intake.Right next to it is the VTEC oil pressure switch . Both have grey connections. If you complain about rough idle then yes service solenoid (they do plug up from low end oil or lack of oil maintance).The code is circuit.that means that battery voltage has to be present. When the code P2647 appears VTC is disabled and valve timing is fixed at a fully ****** position.This is where you say you feel like its running out of gas is from.Switch is you just replaced it, a electrical diag has to be performed.From switch to PCM

THERE IS A RESTRICTION OR A BLOCKAGE SOMEWHERE TO THE VTEC SOLENOID YOU WILL NEED TO CLEAN OUT THE BLOCKAGE TO FIX THIS PROBLEM

Tell me what kind of motor oil r you using.regular or synthetic.

is a vtec solenoid valve. it located on your left behind the valve cover . vtec solenoid looks like a round cap. anyway do you have a oil leaks in your car?

P2647 VTEC Oil Pressure Switch Circuit High Voltage - With Automatic Transmission Basicallly the sensor has gone bad or an oil passage has become blocked.

**. Locate the Variable Timing Electronic Control (VTEC) pressure switch on the end of the cylinder head. Honda has had problems with the VTEC oil pressure switch, there is an updated part number for the vehicle (37250-PNE-G01). On this vehicle the VTEC oil pressure switch can fail at any RPM.
2. The VTEC oil switch is normally closed, and grounds the reference voltage from the Engine Control Module (ECM) on the Blue/Black (BLU/BLK) wire. If the code sets at idle - 2500 RPM - and the Brown/Yellow wire has a good ground, then suspect a faulty VTEC oil pressure switch.
3. At approximately 2500-4000 RPM and when driving the vehicle, the VTEC system should turn on. To turn on the system, the ECM energizes the VTEC Solenoid valve and it allows oil pressure into the intake valve rocker arms, the oil pressure opens the VTEC oil pressure switch so the Engine Control Module (ECM) can verify that the VTEC did turn on correctly.
4. The code will set at idle to 2500 RPM if the reference voltage is not grounded. The code will set above 2500-4000 RPM if the VTEC oil switch does not open.
5. If the code sets at 2500-4000 RPM or higher, the problem can be a low oil level or pressure, or a malfunction in the VTEC assembly.
Potential Causes: Low Engine Oil
Plugged Oil Passage
Insufficient Oil Pressure
Plugged Oil Screen
Insufficient Oil Volume
Malfunctioning VTEC Oil Pressure Switch
Defective VTEC Solenoid
