What Does P207B Mean?
The PCM has detected that the intake manifold tuning valve position sensor on Bank 2 is reading values outside the expected range for the commanded position. The sensor feedback doesn't correlate properly with commanded valve position.
Common Causes
35%
IMT valve stuck or binding mechanically on Bank 2
30%
Failed or degraded IMT valve position sensor Bank 2
20%
Faulty IMT valve actuator motor or solenoid Bank 2
10%
Vacuum leaks affecting Bank 2 IMT valve operation
5%
Sensor calibration drift or PCM issue
Diagnostic Steps
1
Step 1: Monitor live data comparing commanded vs. actual position for Bank 2 IMT valve
2
Step 2: Physically inspect Bank 2 IMT valve for carbon buildup, binding, or mechanical issues
3
Step 3: Command Bank 2 IMT valve operation using bidirectional controls and observe response
4
Step 4: Check vacuum supply and integrity for Bank 2 if vacuum-actuated system
5
Step 5: Test position sensor voltage/resistance and compare to specifications across full range
Estimated Repair Cost
$200 - $800
Parts + labor, varies by vehicle and location
The PCM has detected that the intake manifold tuning valve position sensor on Bank 2 is reading values outside the expected range for the commanded position. The sensor feedback doesn't correlate properly with commanded valve position.
The most common cause of P207B (Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Range/Performance Bank 2) is: IMT valve stuck or binding mechanically on Bank 2
Typical repair costs for P207B range from $200 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive but Bank 2 performance will be compromised. Expect reduced power, rough idle, and poor fuel economy, especially noticeable in V-configuration engines.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P207B to identify the root cause.
