The P1259 code on a Honda CRV indicates a problem with the Variable Valve Timing (VVT) system. Specifically, it means that there is a malfunction in the VVT system’s oil pressure switch circuit.
The VVT system is responsible for adjusting the timing of the engine’s valves, which can improve performance and fuel efficiency.
The oil pressure switch is a crucial part of this system, as it monitors the oil pressure in the VVT system and sends a signal to the engine control module (ECM) to adjust the valve timing as necessary.

When the ECM detects a malfunction in the VVT system’s oil pressure switch circuit, it will trigger the P1259 code and turn on the Check Engine Light (CEL). This can indicate a range of issues, such as a faulty oil pressure switch, a wiring issue in the VVT system, or a problem with the ECM itself.
To diagnose and repair the issue, it’s recommended to take your Honda CRV to a qualified mechanic who can use a scan tool to read the code and identify the root cause of the problem.
They may need to perform further testing on the VVT system, including checking the oil pressure switch, inspecting the wiring, and testing the ECM. Once the issue is identified, they can make the necessary repairs or replacements to resolve the problem and clear the code.

P1259 code on a Honda CRV Tech Note
The P1259 code on a Honda CRV is a diagnostic trouble code that is triggered when the Engine Control Module (ECM) detects a problem with the Variable Valve Timing (VVT) system’s oil pressure switch circuit.
The VVT system adjusts the timing of the engine’s valves to improve performance and fuel efficiency, and the oil pressure switch is a critical part of this system. It monitors the oil pressure in the VVT system and sends a signal to the ECM to adjust the valve timing as necessary.
When the ECM detects a malfunction in the VVT system’s oil pressure switch circuit, it will trigger the P1259 code and illuminate the Check Engine Light (CEL). This can indicate a range of issues, such as a faulty oil pressure switch, a wiring issue in the VVT system, or a problem with the ECM itself.
To diagnose and repair the issue, a qualified mechanic should perform a series of tests on the VVT system, including checking the oil pressure switch, inspecting the wiring, and testing the ECM.
They may also need to check the oil pressure and oil cleanliness. Once the issue is identified, they can make the necessary repairs or replacements to resolve the problem and clear the code.
It’s important to note that the P1259 code can cause reduced engine performance and fuel economy, and if left unresolved, it can lead to further damage to the engine or other components of the VVT system. Therefore, it’s recommended to have the issue diagnosed and repaired as soon as possible by a qualified mechanic.
