    Add 1/2 quart of Dexron VI to the crankcase ant oil change. This will wash the engine out and correct any sticking camshaft advance actuator problems that are dirt related. The ATF will not harm the engine..

    Use only the recommended oil, this VERY important in the VTEC engine, so if you have a heavier oil than called for drain it out.

    It still sounds like the variable camshaft timing actuator is sticking or defective, that is what VTEC stands for correct.

  • Darrell Williams Oct 14, 2012

    is there away to find out if it is defective Dennis or just sticking and do you know what it look like im fix up my friend car for her.

  • Darrell Williams Oct 14, 2012

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

SOURCE: 2004 Honda Civic -Code P0122 Throttle Position Sensor Voltage Low

yes, this is the case of a failed throttle body, in which case it needs replaced, the car is getting too much fuel causing the high idle. this needs replaced asap. you could proably find a small independant honda shop that could do the work for less.

SOURCE: 98 Honda Accord LX CODE 1259

Code 1259 indicates a V-tec system malfuntion assuming your Honda isn't a DX? Disconnect the negative battery cable so that you can clear the code. If code returns, try cleaning and/or replacing the V-tec pressure sensor. I heard of someone that had the same 4000 rpm problem you speak of and this is where they solved their problem. Good luck to you.

SOURCE: ihave a 01 honda civic ex and a p1259 code came on

that code is for a Vtech system malfunction. check your oil level if its ok you should bring the car to honda unless you can handle a multimeter and have oil presure gages and the basic knowledge of how to use these items.

I believe this is a code the VTech engines will set if a oil solenoid valve doesn't open in the cylinder head to provide extra oiling when the engine RPM's exceed 4k. The best I recall the valve in the head is usually faulty if this code is present.

2001 honda civic obd code

reset the ecu pull #6 fuse 15a for 10 msec. check oil level fill if needed. start engine hold at 3 grand for at least 2 sec road test if still comes back 1259 repeat 2 times. If it is gone it is intermit problem check for loose terminals at VTEC solenoid vavle oil pressure switch and the ECM/PCM. If you still have the code turn ignition off remove resonator disconnect the VTEC oil pressure switch 2p connector check for contnuity between VTEC oilpress switch terminals 1 and 2 if none replace the oil pressure switch. if yes measure voltage between ECM/PCM connector B9 and body ground. Voltage? repair open wire between B9 and the oil pressure switch. If no than the ECM/PCM will need to be checked for the latest software and reprogrammed to be further diaged. This will only be able to bedone at the dealer.
