What does VTEC system failure mean?
The most common cause for Error Code P1259 or VTEC system malfunction is low oil pressure. If it’s in bad condition, then replace it with real original Honda oil pressure switch. Lastly, you could have a restricted VTEC solenoid passage, or faulty VTEC solenoid or wiring. Repair or replace as needed.
How do you know if your VTEC is not working?
The meter should read very very low voltage until vtec hits. If vtec activates then the voltage should read around 12. if not then your ecu may not be functioning properly.
What is VTEC oil pressure switch?
VTEC stands for Variable Valve Timing with Electronic Control. The variable valve timing oil pressure switch is a normally open switch located at the VVT solenoid. When the VTEC oil pressure switch closes, the voltage should drop to zero. This is how the PCM knows if oil pressure was applied to the VTEC system.
What causes VTEC to sputter?
Most common cause of that is not enough oil in the pan. It’s usually worse while turning as well (hard turns only of course as you’d have be on the gas hard in VTEC range). Check your oil level, top it up if necessary, go for a drive and report back.
What does the p1259 VTEC malfunction code mean on a Honda?
Honda installs a VTEC pressure switch to detect oil gallery pressure and based on that pressure, the computer determines how long to pulse the solenoid on and off. A P1259 VTEC malfunction code will set if the computer doesn’t detect the intended result after commanding a change in valve timing.
What are the fault codes for a Honda chassis?
Complete Honda Chassis Code list Sources and Thanks About Honda Fault Codes A guide on how to check your codes: The Fault Codes 1 O2A – Oxygen sensor #1 2 O2B – Oxygen sensor #2 3 MAP – manifold absolute pressure sensor 4 CKP – crank position sensor
Why is my VTEC not working?
Low oil level can cause this as well as a bad oil pressure switch for VTEC control, possible VTEC solenoid. You can’t post conmments that contain an email address. An expert who has achieved level 1.
What to do if the V-TEC valve is stuck?
Use synthetic oil, have your valves adjusted, check the solenoid operation, and if nothing else get a gasket set from Honda, it has a new screen installed, and clean the V-tec valve out. It would take just a few minutes to check the oil valve system out to make sure it can move freely, and it only has three bolts holding it in.
