Hi Please Help,

My check engine light comes on and the codes when checked says P1259. Can someone tell me what this code is and how I can fix it? Thanx in advance, I detest seeing the check engine light.

if i remember correctly... 1259 is VTEC System Malfunction :thinking:

Yeah, I found out it's the vtech malfunction, can someone tell me how I can fix this problem as I would like to get the engine code light. thanx in advance.

check your oil level first, I had this happen a couple times and I just needed to top off. if your oil level is fine then take it to the dealership.

The VTEC spool valve assembly is #11 bolted on the back side of the head. Picture is a little goofy, that spool valve is actually over towards the distributor-end of the head. Check the plug on the VTEC oil pressure switch #14 - if that's loose/dirty/corroded or broken wires that can cause it. Also check the electrical connection to the VTEC solenoid on top of that assembly.



Sometimes the spool valve is sludged up.

If you feel comfortable doing this, unbolt the assembly from the head & clean out the screen in the gasket #13. Better yet, get a new gasket from a dealer because it'll probably be hardened with age & leak when you put it back together.

Thanx again Jim, and others who responded, I will definitely check this out and get back to you.

My engine light used to come on all the time. If you have a 5 speed it's because you don't shift at high enough RPMs

ugh i hate to be doing this kgilpat40 cause i feel like u will be offended because i bashed your other post. but honestly.... that is a ridiculous hypothesis IMO. you would think honda would have realized, hey if im not shifting this beezy until 7k the check engine light comes on. i may be wrong but i definitely dont think that is any excuse for the light to come on. but then again... i am ignorant on occasion.
