P1259 Honda Code - VTEC System Malfunction

I have tried all the above on a Honda Accord 99 and it is still showing the code P1259 and when you mash the accelerator the engine just shuts off! Could any one give me any advice please. Thanks.

What oil weight are you using and when was the last time you change the oil and filter?

My question would be if it was to be a faulty solenoid or oil pressure switch how would I test that, Would i need to test for continuity or are the specific tests to test these things?

For the oil pressure test you need an oil pressure gauge. Most of the times the problem with the solenoid is not electrical, but mechanical. Dirty oil cause the solenoid to get stuck.

Would this be as simple as removing it and cleaning it out if need be? Or is it better to just replace it

I seem to have the same issue. I was told today that my oil pan was dented by my oilchange tech.. Bet this has something to do with it.

Yes, definitely. Dented oil pan could cause a lack of engine oil flow.

I've done all this process still have flashing light.

Could you please explain what exactly have you done? what model and year is your Honda?

would this also cause the car to not rev over 4000 rpm por would that be the knock sensor. im asking because the problem is my rpm is not passes 4000. thats my only problem

i thought it was the speed sensor but nothing changed after i swapped it out

What model and year is your Honda? how is the engine oil level and condition?

1999 Honda accord. IDK the oil level, i need to check it. But it happened after i changed my head gasket. After cleaning the whole engine out o changed the oil and filter. Also put new oil in it.

Start by checking the engine oil level and condition if the oil level is OK, then the next step is to replace the VTEC solenoid valve.

Well I'm putting an F22 dule V-tec engine head on it so the intake head and header is being changed. I just want to fix that problem before i put the new stuff in

I have had the 1259 on my 99 accord since I bought it. I know that the guy that bought it from the auto auction said that the oil was low when he brought it to his garage. He put the wrong viscosity oil in it. I have changed the oil 2x, with the correct oil, the last time also replacing the pan gasket (leaking). I had the car scanned last week and I still have the 1259 (and knock sensor, no signal code P0325) with one code pending. Can you tell which code is pending? Could it be the 1259? Does the knock sensor code,P0325, have anything to do with the vtec code?

The scanner is the only device that should let what code is pending. If you already change the engine oil and you still get the code, you may have to replace the VTEC solenoid valve. There is a chance that the knock sensor code could be trigger by a faulty VTEC system.

since I do not understand how the scanner works I was wanting to know if the pending code could possibly also be one of the two codes that came up. (1259 & P0325) I was hoping that doing the new pan gasket would fix the 1259. Would 1259 still come up as a code if it was in "pending" status?(or are we talking about 3 possible codes?) My garage mechanic didn't tell me much (knowing things that I do not know is how he makes his money)...So to repeat, I have changed the oil 2X, the 2nd time I had a new pan gasket done, yesterday I drove it and paid attention to the RPMS and I do rev over 4,000 when going 55 up a steep incline. So I pass that test. BTW, it is a 4cyl. if that has any bearing.

I have 98 Honda accord one side of my sip stick says it's oknthenother side says it's low so what shall I do?my engine light keeps coming on sometimes it goes off I also get p 1259 code

Since you also have the code, the you should start by changing the engine oil and filter.

Can a leaking oil pan cause my car to hesitate when accelerating? I just got the code today after i cleaned the throttle body and the Solenoid. At one point i can't rev pass 4,000 rpm. turned the engine off and back on again. rev could go up to rpm limiter again but still have the acceleration hesitation. I also notice a little leak of oil, not very noticeable cause its not leaking that bad until you actually look around the oil pan gasket.

No. Leaking oil pan wont cause that problem. Wrong oil weight, damage oil pan (dent on oil pan) or lack of oil could the code.

So on my 99 accord I have a p1259 code. What is the first step I should take? Im assuming change the engine oil. But could it really be that simple? And If I change it and clear the code and it comes back then should I jump right to changing to solenoid?

Depends how bad is the oil. You may have to change the engine oil a couple of times (change oil, clear code, drive for about 3K miles and change again) to fix the problem. If changing the engine oil a couple of times wont fix the problem, the you can consider changing the solenoid.

What exactly is it called that I'm looking to replace as I'm getting the p1259 code and have changed oil.

VTEC solenoid valve. What model and year is your Honda?

OIL IS CLEAN AND JUST RIGHT P1259 CODE IM SURE AFTER ALL IVE READ AND CHECKED ON THE OIL ITS THE VTEC SOLENOID. AT HIGH SPEEDS (65) ANY ACCELERATION STOPS. 2003 CRV 135K

Hey so you think it could really be the dent on my oil pan that i got, ive changed my oil when i need to all the time and put on a new v-tech solenoid recently and still gives me code and exact discription of lack of speed and cant pass 4k rpms

All depends how bad is the dent. A dent on the oil pan could starve the engine of oil.

To my opinion it doesn't look bad but it did get pushed in. I do recall hitting something really hard and after that getting a different performance can it change performance right after impact?

Yes, hitting the engine can change performance. You should have your vehicle check up by a tech. Have them check for damage not only to the oil but other components as well.

I have a Honda crv RD4 which recently had an oil leak, the mechanic had to change the vtech unit in order to stop the leak. Driving off from the mechanic I noticed when I accelerate the car starts jerking and holding back. The leak is gone but the jerking still happens I recently changed oil and it drove ok for a few miles then it started jerking again could you please tell me the issue.

My Honda accord 2000 is bringing the p1259 code and the spark plugs is getting black... Anytime I changed them and also the car is jerking. I have service the 2nd clutch pressure switch and seloniod . It work for an hour journey then start again.

I have same code, it is crv, no issue in town, only starts jerking with no power when driving on highway, it happens sometimes, most of the time the car drives perfect even on highway, replaced vtec selonid valve but still same problem. no leak from the valve. Oil level good. ANY IDEA?
Thank you

i have received the p1259 code and when i do my 2002 honda accord wont start if it set a day or two then it will start right up. Is there anythingelse other then a faulty solenoid or dirty oil that could be causing my issue of not starting?

No, the no starting problem is a different issue. Even with the solenoid disconnect you should be able to start the engine.

i have a 2002 civic , just replaced the motor with a jpm motor with 50000 miles . new oil and filter still sets 1259 code . had a 1298 but changed the sensor and erased code, did not come back was hoping it was setting the 1259 no luck

2000 honda accord puts that p-1259 code so what should i do to fix it

You could start by changing the engine oil and filter. If the problem persists you may have to replace the Variable Valve Timing and Lift Electronic Control (VTEC) solenoid.

My 2003 pilot has p1259 code and is leaking oil from somewhere around btec variable timing sileniod changed the oil pressure switch and solenoid still runs super rough please help

When was the last time you change the engine oil and filter? you should start by changing the engine oil and filter and clean the leaking oil. If the problem persist you may have to replace the replace Variable Valve Timing Control Solenoid.

Yo tengo código p1259 en honda crv2002 ya cambié la válvula vtec, el solenoide cambié filtro y aceite la malla también y nada sensor de detonación , cadena de tiempo y sigue apareciendo el código
