2002 honda civic p1259 problem


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

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.

My car is a 2000 vtech honda civic. Engine light stays on even after I took the car to the mechanic and changed the oxygen sensor, which they said was the problem. I took it to another place and I am...


TELL ME WHAT CHECK ENGINE LIGHT CODE YOU ARE GETTING.CODE SCAN AND TELL ME WHAT CODE YOU ARE GETTING.MOST VTECH ENGINE HAS PROBLEM WITH VTEC SOLENOID OR VTEC OIL PRESSURE SWITCH.MOST TIME CHECK THE OIL PRESSURE BY REMOVING VTEC OIL PRESSURE SWITCH FROM THE LOCK UP SOLENOID AND CONNECT AN ADAPTER BETWEEN THE SWITCH AND THE SOLENOID. BUT I CANT SAY ITS YOUR VTEC SYSTEM UNTIL YOU CODE SCAN CAR.OIL PRESSURE SHOULD BE 50 PSI @ 3000 RPM OR 85 PSI @3000 RPM.

I have code p1259


code 1259 is the actual v-tech code and oil pressure codes go from po520-po523. Many people do not have any idea what v-tech actually means. It's an actual oil solenoid valve that opens up above 4000 rpms and adds extra oiling to the cylinder head. To set this code po1259 you would have had your car above 4000 rpms for more than 3 seconds i believe and have this valve not work. Chances are that the valve it's self in the head is bad and setting this code. I have had it happen on a few other Honda's

I have a Honda 2004 CRV - the repair ( OBD II) code is P2647 - what does that mean?


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

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.

What the previous owner told you could be correct(that is 33mpg), B16A1 Vtec engine were made for power and fuel efficiency. Your clutch upgrade would not affect your fuel consumption unless you feel anything slipping during acceleration. I say you give your engine a good tune up and compare the milage again.

Vtec check


hi you will know if it works it don,t kick in till the engine reachs a certain rev range usually around 3000 rpm then it transferes to the hi lift cam and when it kicks in will feel like a turbos been fitted. if not you have a problem with it which would likley be a problem with its solenoid or oil pressure. yates210456
