What Does P206E Mean?
The intake manifold tuning valve on bank 2 is stuck in the open position and cannot close properly. This valve optimizes airflow at different engine speeds but is mechanically jammed or electrically faulted in the open state.
Common Causes
40%
Carbon buildup causing IMT valve to stick open
30%
Failed IMT valve actuator motor or linkage broken/disconnected
15%
Faulty IMT valve position sensor indicating incorrect position
10%
Vacuum leak or failed vacuum actuator for IMT valve
5%
Damaged or binding IMT valve butterfly plate or shaft
Diagnostic Steps
1
Step 1: Locate IMT valve on bank 2 intake manifold and attempt manual operation of valve mechanism to check for binding
2
Step 2: Command IMT valve closed using scan tool bi-directional controls and observe valve movement
3
Step 3: Check IMT valve position sensor voltage or feedback signal to verify accurate position reporting
4
Step 4: Inspect for vacuum leaks if vacuum-operated, or test actuator motor operation if electric
5
Step 5: Remove IMT valve assembly and clean carbon deposits from valve and manifold ports with intake cleaner
Estimated Repair Cost
$250 - $1,200
Parts + labor, varies by vehicle and location
The intake manifold tuning valve on bank 2 is stuck in the open position and cannot close properly. This valve optimizes airflow at different engine speeds but is mechanically jammed or electrically faulted in the open state.
The most common cause of P206E (Intake Manifold Tuning (IMT) Valve Stuck Open Bank 2) is: Carbon buildup causing IMT valve to stick open
Typical repair costs for P206E range from $250 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive but may experience reduced low-end torque, rough idle, or decreased fuel economy.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P206E to identify the root cause.
