What Does P206F Mean?
The intake manifold tuning valve on Bank 2 is mechanically stuck in the closed position. This valve adjusts intake runner length for optimal engine performance across different RPM ranges.
Common Causes
40%
Carbon buildup or sludge jamming the IMT valve mechanism
30%
Failed IMT valve actuator motor or solenoid
20%
Broken or seized linkage/flap mechanism inside intake manifold
10%
Wiring or connector issues preventing valve operation
Diagnostic Steps
1
Step 1: Locate the IMT valve actuator on Bank 2 and attempt manual actuation to verify mechanical binding
2
Step 2: Command the IMT valve through bidirectional controls using scan tool while monitoring position sensor feedback
3
Step 3: Inspect actuator connector and wiring for damage, corrosion, or loose connections
4
Step 4: Remove intake manifold if necessary to inspect valve flap for carbon deposits or mechanical damage
5
Step 5: Test actuator motor resistance and operation with direct power application if needed
Estimated Repair Cost
$300 - $1,200
Parts + labor, varies by vehicle and location
The intake manifold tuning valve on Bank 2 is mechanically stuck in the closed position. This valve adjusts intake runner length for optimal engine performance across different RPM ranges.
The most common cause of P206F (Intake Manifold Tuning (IMT) Valve Stuck Closed Bank 2) is: Carbon buildup or sludge jamming the IMT valve mechanism
Typical repair costs for P206F range from $300 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive but engine performance and fuel economy will be reduced, particularly at specific RPM ranges. May experience rough idle or hesitation.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P206F to identify the root cause.
