The P1259 : is problem in the VTEC Oil Pressure Switch circuit or VTEC Solenoid Valve circuit.
check the wire on the VTEC Oil Pressure if it's loose.

Hi i have a 1997 honda acccord lx with a vtec engine i got the check engine light and scanned, recieved dtc code p1259 vtec system failure the symptoms are it driving normal until it reaches 3,500 rpm


If this is a 1997 LX Accord, it did not come with the VTEC, that was only on the EX version in 1997. So someone put an EX VTEC engine in your LX. I've seen this done, and it requires a EX pcm computer. It also needs VTEC wiring to be installed. Check the engine serial # and ID what this engine is from.
If this is actually an EX Accord, then there are more things that can fail than the solenoid. The pressure switch is a common failure.

How to fix VTEC System Malfunction code P1259


It is the wire close to the VTEC valve solenoid plug be cut off. Sounds wired, but it happened to my 2001 accord EX V6 sedan. After I solder it back, the TCS light turned off. But I had to disconnect the battery for 5 minutes and put it back to reset the Check Engine light.

How to replace cam shaft sensor


Assuming you have the 2.3 L 4 cylinder engine, the CYP sensor [Honda does not call it a camshaft sensor] is located in the distributor. It also has 2 crankshaft sensors, located down at the front of the crankshaft. You need to remove the timing belt covers to access those.
FYI, P1259 is a VTEC system [variable valve timing] malfunction code. First step would be to change the engine oil and filter. Dirty oil can cause the VTEC solenoid to stick.

My honda accord 2003 V6 hiccups when I step on the gas, and the right signals do not work. The code P1259 came up and I was wondering excatly what does that mean?


This is an error code related to VTEC related Honda engines. I am sending you a little reading on that error code.. Best of Luck..


The Check Engine Light (CEL) is on. Trouble code P1259. Tests/Procedures: 1. Locate the Variable Timing/Lift Control (VTEC) pressure switch, on the back of the cylinder block, by the oil filter.

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.

3. At approximately 4000 RPM, and when driving the vehicle, the VTEC system should turn on. To turn the system on, 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 ECM can verify that VTEC did turn on correctly.

4. The code will set below 4000 RPM if the reference voltage is not grounded. The code will set above 4000 RPM if the VTEC oil switch does not open.

5. If the code sets at 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
Tech Tips: When the P1259 code sets at 4,000 RPM or higher, always verify that the engine oil level is full. Also, if there is an oil pressure or volume problem, always verify that the oil pan is not pushed up and is too close to the oil pickup tube, causing an oil volume problem. Be very careful when supporting the engine with the oil pan.

Code p1259


low oil level can cause this as well as a bad oil pressure switch for VTEC control, possible VTEC solenoid.
Another reason for this code is the immobilizer. the anti theft device that looks at your key for the diode to match the car. This is on cars with out the VTEC.
On the VTEC system
DEFINITION:
VTEC System Malfunction

PROBABLE CAUSES:
-Low oil/pressure
-Blocked oil pressure
-Failed VCT oil control valve

I have a code popping up as p1259 i have gotten some info on it i was told to get a new oil pressure switch. is that correct or what else would cause it.


Code P1259 is a VTEC System Malfunction. I don't think there's a code for a bad oil pressure switch, just an oil dash light.

I have a 1998 Honda Accord the service engine soon light came on. I failed inspection and was told I had a Diagnostic trouble code P1259.(1) What does P1259 trouble indicate. (2) How do you turn off the...


p1259 is a problem with the VTEC system. this system is for improved performance at higher rpm's. oil can get sludged up and clog the system, or the VTEC solenoid can just go bad. you can always have someone with a scan tool clear the codes to turn off the light, but until the problem is fixed, it will just keep coming back on
