Solution for Toyota 86 - Issues with the Engine's Variable Valve Timing System

The Toyota 86 is a popular sports car known for its impressive performance and handling. However, some owners have reported issues with the engine's variable valve timing (VVT) system, which can cause problems such as decreased performance, difficulty starting the engine, and increased fuel consumption. In this article, we will explore the root causes of these issues, identify the models most affected, and provide insights into consumer feedback and potential preventative measures.

Introduction to VVT Issues in Toyota 86

The VVT system in the Toyota 86 is designed to improve engine performance and efficiency by adjusting the timing of the valves. However, when the system fails, it can cause a range of problems, including decreased performance, difficulty starting the engine, and increased fuel consumption. The most common cause of VVT issues in the Toyota 86 is related to problems with the VVT solenoid, which can become clogged or faulty, preventing the VVT actuator from functioning properly.

Overview of the VVT System Issue

The VVT system issue in the Toyota 86 can cause a range of symptoms, including: * Decreased performance * Difficulty starting the engine * Increased fuel consumption * Check engine light * Rattling or ticking noises The issue is most commonly associated with the 2013-2016 models, which were equipped with the FA20 engine. However, it can also affect other models, and it is essential to be aware of the potential causes and preventative measures.

Common Causes of VVT Issues

The most common causes of VVT issues in the Toyota 86 include: * Problems with the VVT solenoid, which can become clogged or faulty * Dirty oil, which can clog the VVT solenoid and cause problems * Faulty camshaft position sensors, which can prevent the VVT actuator from functioning properly * Software issues with the engine control unit (ECU), which can cause problems with the VVT system It is essential to identify the root cause of the issue to determine the best course of action for repair.

Repair Options

The repair options for VVT issues in the Toyota 86 depend on the root cause of the problem. In some cases, replacing the VVT solenoid may be sufficient to resolve the issue. However, in other cases, more extensive repairs, such as replacing the ECU or camshaft position sensors, may be required. It is essential to consult with a qualified mechanic to determine the best course of action for repair.

Models Most Affected

The Toyota 86 models most affected by VVT issues are the 2013-2016 models, which were equipped with the FA20 engine. These models have been known to have issues with the VVT system, including difficulty starting the engine, decreased performance, and increased fuel consumption. The 2017 and later models have been updated with a new engine and VVT system, which has reduced the incidence of these issues.

Consumer Feedback

Many Toyota 86 owners have reported experiencing issues with the VVT system, including difficulty starting the engine, decreased performance, and increased fuel consumption. Some owners have reported that the issues have been resolved by replacing the VVT solenoid, while others have required more extensive repairs, such as replacing the ECU or camshaft position sensors.

Preventative Measures

To prevent VVT issues in the Toyota 86, it is recommended to: * Regularly check the oil level and condition, as dirty oil can clog the VVT solenoid and cause problems * Avoid extreme driving conditions, such as high-performance driving or towing, which can put excessive stress on the VVT system * Stay aware of any software updates or recalls related to the VVT system * Have the vehicle serviced regularly to ensure that any issues are identified and addressed promptly By following these recommendations, Toyota 86 owners can help prevent VVT issues and ensure that their vehicle runs smoothly and efficiently.
