SOURCE: what should i do? B16 or piston rings?

well its about what you want the single cams can rev high...the 2nd fastest world record is in a turbod d16 ...202mph for a single cam civic..the b16 has more dynamics in the high end of boosting... the b16 aftermarket is stronger but they **** on the low end of the rpm gauge..
the best motor is the b20 crv block its 500 bucks you can vtec it with a b16 head and run big loads of turbo and get to the 10 sec class of things...if you go to b series you will need to change the ecu to hondata and you should look for ls integra trannys...next the axles ...I reccomend B20 its a harder build but its worth it and youll spend 1000 less than an gsr or prelude motor...google the b20 dart motor with ITBS you will see!!!!!!!!

SOURCE: vtec does not work

My guess is your vtec went into "limp mode". There are various reasons why it does this but it is a precausionary measure the ecu takes when there is an issue. I have a 5th gen so I am not an expert on the 4th gens but it is a question raised by many lude owners. Go to preludezone or preludeonline and check the forums...wealth of info there.

What does a po1259 code for a 2001 honda accord 3.0 litre, v-tec b-1 sys. failure mean


Here is the explanation from engine-codes.com

P1259 Honda Description
The VTEC system activates the VTEC solenoid valve by command from the powertrain control module (PCM), and it charges/discharges the hydraulic circuit of the VTEC mechanism that is installed in the valve system to switch valve timing between Low and High. The PCM monitors oil pressure conditions in the hydraulic circuit of the VTEC mechanism according to the VTEC oil pressure switch downstream of the VTEC solenoid valve. If there is a disparity between oil pressure condition in the hydraulic circuit that is determined by the PCM command, and the oil pressure condition that is determined by the status of the VTEC oil pressure switch, the system is considered faulty and a DTC is stored.

Why a 1997 honda civic engine surges at idle


which engine, options there are many.???
cant fix any engine, until you know what it there.
a civic not Tacoma. as posted.
see end for engines ????

surge 101 (running gasoline?)
it caused by 2 things. (and lots of reasons)
1: engine running lean. all engines lean surge. fix that first.
hint use a scan tool see live data........?????
2: ISC system is faulting, the idle speed controller can fail for #1
or for itself. (it can stick) clean in.


wiki list of engines. (which one???????????????)_
The sixth generation featured engine options were available along with their first Natural Gas Powered Civic, the GX. From 1996-2000 the Civic was sold under the CX, DX, EX, EXR, HX, LX, and for Canada, SE, and Si trims; all base models were made with 1.6L engines. The EX-CX are all SOHC (Honda D engine). The CX, DX, and LX all have D16y7 non-VTEC engines; whereas the EX has a D16y8 VTEC, and the HX has D16y5 VTEC-E. The USDM Si and Canadian SiR came with a DOHC (B16A2 VTEC). The first civic SI coupe EM1 was introduced in 1999 until 2000. Europe saw a DOHC 1.6 VTI hatch and sedan and a DOHC 1.8VTI engine was available for the Domani related five-door liftback and esta

I have a 2004 Honda Civic VTI, the engine checklight came on and I went to 3 different computer diagnostic centres and the scan showed VTEC system failure. I changed the VTEC solenoid, change vtec pre


What is wrong is that you changed a part

You failed to follow any trouble charts because
you have none

The sensor was most likely okey & just doing it's
job of reporting a fault

You could have a mechanical problem such as a timing
belt issue or worn VVT Actuators on the end of the cames

You have to diagnose code related issues & then find out
why a sensor reported as it did

Even if you scoped the sensor you would most likely
assume it was bad,not so,have to keep thinking why the
data was bad

You need professional tools & look at several pieces of data
overlayed on a big sceen at one time

Repair shop or dealer for that issue

Code p1259


Hi there:
There is actually an old service news about this very code. there are two things that could be at fault but you will have to check a few things that are outlined in the article before knowing which parts need replacing... please read carefully below...

MIL with DTC P1259 - Vtec System Malfunction

On 1998 Accord L4s with VTEC, DTC P1259 (VTEC system malfunction) can set at idle or above 4,000 rpm:

If it sets at idle, the problem is with the VTEC pressure switch circuit (switch, connectors, or wiring).
If it sets above 4,000 rpm, the cause is low oil pressure in the VTEC system.

To find and correct the cause of the DTC, do this:
1. Use the PGM Tester to check the vehicle's freeze data or snapshot data to see when the DTC was set.
If it set at idle, go to step 2.
If it set above 4,000 rpm, go to step 4.

2. Disconnect the 2P VTEC pressure switch connector, and jump its two wires.

3. With the ignition switch ON (II), the PGM Tester should show that the VTEC pressure switch is ON.
If the Tester says the switch is ON, the wiring and connectors are OK, so the switch must be bad.
Replace the switch, clear the DTC, and return the vehicle to the customer.
If the switch is OFF, check for an open circuit between the switch and the ECM/PCM or between the switch and ground. After you repair the open circuit, recheck the switch, then clear the DTC, and return the vehicle to the customer.

4. Remove the valve cover, and check for a loose center head bolt on the intake manifold side. A loose bolt can cause a drop in pressure in the VTEC system.

If the bolt isn't loose, go to step 5.
If the bolt is loose, torque it to 22 lb-ft (29 Nm), turn it another 1/4 turn, and then turn it another 1/4 turn. If the bolt won't tighten, its threads are probably stripped.

5. Remove the VTEC rocker arms, and inspect them for sticking or missing synchronizer pistons or other valve train problems that could cause an oil leak.

If you find any piston or valve train problems, replace the faulty parts. Then clear the DTC, and return the vehicle to the customer.
If the pistons and the valve train are OK, do the DTC P1259 troubleshooting procedure on pages 6-7 thru 6-9 of the '98-99 Accord S/M.


Hope this helps; also keep in mind that your feedback is important and I will appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

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

Just got a P1259 code on my 98 honda accord


I have a 1998 Honda Accord EX. I had the check engine light come on as well and I had the code read by PepBoys. The code was:P1259 or VTEC SYSTEM Malfunction.
I Don't know jack about were to start to fix this problem, so I bit the bullet and took the car to my Honda Dealer. The problem was checked out and was told this.
( REPLACE VTEC VALVE ASSEMBLY)
I had them do the work because I dont know how to do this. So after $204.00 in Labor and $162.29 in parts, for a grand total $366.29, The car was fixed!!!!!!! Run's great and no check engine light on anymore. So to help you out as best I can, here is the numbers that are on my work sheet. I dont know witch numbers represent the part number but this is how it looks on my paper.

1 15810-PAA-A02 8108797-90870 VALVE ASSY, SPOOL $150.75

1 15825-P0A-015 8161598-15999 FILTER, SPOOL VALVE $11.54

There you go! I hope this gives everyone a place to start. maybe get your self a Haynes Repair Manual (#42014 is for the 1998-2002 Honda Accord, all models) and try to do the work your self. Good luck to all of you form Donald M. in SoCal.
