P1349 Scion Code - Variable Valve Timing System Malfunction Bank 1
Quick Answer
The P1349 Scion code indicates a Variable Valve Timing (VVT) system malfunction on Bank 1 of the engine. Common causes include Faulty VVT oil control valve: The valve responsible for controlling oil flow to the VVT system may fail, leading to timing issues, Camshaft phaser malfunction: The camshaft phaser, which adjusts the camshaft timing, may be faulty, Timing chain issues: Problems with the timing chain can affect the timing of the valves. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1349 Scion Description
The P1349 Scion code indicates a Variable Valve Timing (VVT) system malfunction on Bank 1 of the engine. The VVT system is responsible for controlling the timing of the opening and closing of the intake and exhaust valves in relation to the engine's RPM and load. This system helps optimize engine performance, fuel efficiency, and emissions. When the VVT system malfunctions, it can lead to poor engine performance, reduced fuel efficiency, and increased emissions.
Common Causes of P1349 Scion
- Faulty VVT oil control valve: The valve responsible for controlling oil flow to the VVT system may fail, leading to timing issues.
- Camshaft phaser malfunction: The camshaft phaser, which adjusts the camshaft timing, may be faulty.
- Timing chain issues: Problems with the timing chain can affect the timing of the valves.
- Low engine oil level or dirty oil: Insufficient or dirty oil can impact the VVT system's operation.
- Electrical issues: Wiring problems or sensor failures can also trigger the P1349 code.
Symptoms of P1349 Scion
- Rough idling: The engine may idle roughly or inconsistently due to improper timing of the valves.
- Decreased fuel efficiency: A malfunctioning VVT system can lead to increased fuel consumption.
- Loss of power: The engine may feel sluggish or lack power when accelerating.
- Engine misfires: Misfires can occur due to improper timing of the valves.
- Illuminated check engine light: The P1349 code will trigger the check engine light to come on, indicating a problem with the VVT system.
How to Fix P1349 Scion
- Diagnose the issue: Use an OBD-II scanner to retrieve the P1349 code and perform further diagnostics to pinpoint the exact cause of the VVT system malfunction.
- Inspect VVT oil control valve: Check the VVT oil control valve for proper operation and replace if necessary.
- Check camshaft phaser: Inspect the camshaft phaser for any damage or malfunctions and replace if needed.
- Verify timing chain condition: Ensure that the timing chain is in good condition and properly aligned.
- Clear codes and test drive: Clear the diagnostic trouble codes, reset the engine control unit, and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P1349 Scion
The cost of repairing a Variable Valve Timing System Malfunction on Bank 1 can vary depending on the specific cause of the issue and the labor rates in your area. On average, the repair cost can range from $300 to $800, including parts and labor. However, it's important to note that prices can be higher at dealerships or in metropolitan areas, while independent shops may offer more affordable rates. Additionally, diagnosis time and labor rates can also influence the final cost of the repair. It's recommended to obtain quotes from multiple auto repair shops to compare prices and ensure a fair deal.
