both are good in repairing

Only if you want to take the time to trace a wiring diagram down for both engines.

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.

You might want to check the ECU of the engine that u swapped it to. Because the original ecu is only for the 1.4L non vtec!!!

The 1996 civic has a 1.6L b-16 engine. The only difference between the v-tec and non v-tec engine is the dual overhead cam i believe. The 93 civic also should have a b-16 engine in it. The cylinder head should work.......

If youe engine is stock - the VTECH should kick in at 5000-5500RPM.
Your car should be Dyno set. Every vehicle is different.

The 5000-5500 is good because if you were to set it down low it would almost be like having a non-vtec motor. If you set it at 6000, and your redline is 7000 then its not going to realy do anything. Again, almost like having a non-vtec motor.

PIC2
PIC3

The first two pics are examples of where VTEC should be set earlier to smooth out the curve - the latter is an example of where VTEC should be set later to smooth the line out. You want the least noticeable transition from the non-VTEC to the VTEC lobes on your cam. That's when you'll make the most power at every point in the rev range.

Too early and your engine stumbles while it tries to get into the efficiency range of your big lobe- Too late and you have a huge jump where you could have had more power a few hundred rpm sooner.
The first graph had the VTEC set later (4400rpm) so that I wouldn't be jumping in and out of VTEC all the time on the highway, the second is the stock S2000 (6000rpm) that Honda sets so that the customer can feel the VTEC kick in (sells cars because it's cool, but isn't the best for max power), and the third was just set too early because it wasn't a custom tune.

Hopefully that gives you a more visual explanation of why you want to set your VTEC crossover point on a dyno.

Another suggestion is to unplug the IACV (Idle Air Control Valve) and see if the bog persists.

Finally - you may have a clogged cat. Remove the plug for the Throttle body Sensor and check again for the bog.

If no bog under this condition - your cat must be gutted, removed, or replaced.

Thanks!!

ok lets break this down
Vtec= Variable Valve Timing and Lift Electronic Control

if you look on the the motor on the left side youll see 2 things the distributor and the vtec solenoid.. the vtec solenoidif the smaller of the 2 thats it m8 theres 2 wires running from it .. all vtec does is lift the cams on a high 3rd lobe :) rides in the middle of the 2 smaller cam's on a automatic it should pop around 5.200 rpms on a honda ecu thats not tuned.. also a exaust helps or a intake that produce a higher tone thats unmistakeable when vtec hits.. its a beautiful thing hit me up with any! honda stuff ive done swaps to my 92 prelude si 2.2l vtec and many more so i know a honda engine and wireing like theback of my hand

Perhaps you need an ecu "computer" to match your zc engine. A wiring harness to match as well.
