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.
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)
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
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.
Low Engine Oil
Plugged Oil Passage
Insufficient Oil Pressure
Plugged Oil Screen
Insufficient Oil Volume
Malfunctioning VTEC Oil Pressure Switch
Defective VTEC Solenoid
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.
