Why does my car have an error code p1259?
As with other error codes, Error Code P1259 activates the Check Engine light and registers the code to the vehicle’s memory system. Other than that, there are usually no drivability issues and concerns that go along with this error code. This error code can be caused by multiple of factors, such as: Low oil pressure or low engine oil level
What is the error code for a VTEC oil pressure switch?
The PCM will oversee the system and should there be any disparity between the oil pressure condition in the hydraulic circuit determined by the PCM command, and the oil pressure determined by the status of the VTEC oil pressure switch, then this system will be read as a fault, setting the code P1259.

P0252 is a diagnostic trouble code (DTC) for “Injection Pump Fuel Metering Control “A” Range/Performance (Cam/Rotor/Injector)”.
What is the fuel injector circuit code p0201?
For example, a fault with an injector in cylinder one would give a code of P0201. These are all, fuel & air metering injector circuit related codes. Another helpful diagnostic tool is an engine stethoscope. This tool enables a car owner, to listen for any problems with the fuel injectors; by placing the tip of the stethoscope on each injector.
P1259 Honda Possible Causes. Low engine oil level or oil pressure. Faulty Variable Valve Timing and Lift Electronic Control (VTEC) solenoid. VTEC Solenoid harness is open or shorted. VTEC circuit poor electrical connection. Faulty VTEC oil pressure switch.

What causes a VTEC system to malfunction?
NOTE: While there are some exceptions, the general rule is that if the code sets at, or just above idling speeds, the fault is caused by a general electrical issue, while if the code sets above about 4000 RPM, the fault almost invariably involves insufficient oil pressure, or a failure of the VTEC oil pressure sensor. None found.
The PCM will oversee the system and should there be any disparity between the oil pressure condition in the hydraulic circuit determined by the PCM command, and the oil pressure determined by the status of the VTEC oil pressure switch, then this system will be read as a fault, setting the code P1259.

When is the p1259 code detected in a powertrain?
When is the P1259 code detected? The Variable Valve Timing and Lift Electronic Control (VTEC) system activate the VTEC solenoid valve by the 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.
Why does my Honda CRV have a p1259 code?
I’d been getting a P1259 for some time and ruled out the oil level. It just wouldn’t go away so I bit the bullet and rolled up my sleeves. I replaced the gasket and found the old one pretty full and clogged. It was a pain in the butt to get to, but I managed to do it. Was pretty happy until about a day after, the code resurfaced.
What to do if your VTEC system malfunctions?
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.
Can a bad oil pressure switch cause VTEC system malfunction?
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. An expert that has over 10 points. An expert whose answer got voted for 2 times.

When is the code detected on Honda CRV?
When is the code detected? 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.
How does the VTEC system work on a Honda Accord?
The VTEC system controls the valve timing in your Honda. It does this by activating the VTEC/Rocker arm solenoid. It uses the Rocker Arm oil pressure switch to monitor the pressure of this system. P1259 specifically means that there is an issue with the VTEC circuit itself. Although, mechanical issues can cause the code to register as well.
Why is my Honda Accord p1259 not working?
This is facilitated by sending oil into the VTEC system, which changes the engine timing. A good rule of thumb is that if the P1259 code sets at 4000 RPM or below, it’s usually the VTEC pressure switch wiring issue or bad switch. If it is set at 4000 RPM or greater, it’ll usually be an oil related issue.
How does the variable valve timing and lift ( VTEC ) system work?
The Variable Valve Timing and Lift Electronic Control (VTEC) system activate the VTEC solenoid valve by the 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.
How much does it cost to repair a Honda p0325 code?
Replacing the knock sensor usually takes care of the problem. The cost to diagnose the P0325 HONDA code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
Why does my Honda CRV get a p1259 code?
That’s usually caused by a leaking head gasket. This would hurt the oil’s viscosity and trigger the P1259. If you get this code while the engine speed is high, it is a strong indication that the oil going to the VTEC system was insufficient, too dirty, or the wrong viscosity.
When is the code detected? 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.
