P200B Meaning
The P200B: Intake Manifold Runner Performance Bank 2 code indicates a problem with the intake manifold runner system on Bank 2. The intake manifold runner system helps optimize airflow through the intake manifold at different engine speeds by adjusting the position of valves or flaps within the intake runners. When performance is affected, it can lead to poor engine breathing, reduced power, and inefficient combustion.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to look for additional codes that may provide further information about the intake manifold system or engine performance. | OBD-II Scanner |
| Test Intake Manifold Runner Performance | Use a diagnostic tool to monitor the intake manifold runner system’s performance. Check if the runners are opening and closing correctly based on engine speed and load conditions. | Diagnostic Tool |
| Inspect the Control Valve | Visually inspect the intake manifold runner control valve for signs of malfunction, such as sticking, poor operation, or failure to open/close. | Flashlight, Multimeter |
| Check Intake Runners for Blockage | Inspect the intake manifold runners for blockages or damage that could restrict airflow. Clean or repair any issues that may be affecting airflow. | Flashlight, Intake Cleaner |
| Test the Runner Control System | Use a diagnostic tool to check the functionality of the intake runner control system, ensuring the actuator or vacuum system operates correctly. | Diagnostic Tool, Vacuum Tester |
| Inspect Wiring and Connections | Inspect the wiring and connections related to the intake manifold runner system, ensuring that there are no loose, corroded, or damaged connections. | Flashlight, Multimeter |
| Clear the Code and Test Drive | After completing repairs, clear the P200B code using an OBD-II scanner. Take the vehicle for a test drive to ensure that the issue is resolved and the intake manifold runner system is working correctly. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After the test drive, re-scan the vehicle to confirm that the P200B code has not returned. | OBD-II Scanner |
