What Does P207D Mean?
The intake manifold tuning valve position sensor circuit on Bank 2 is reading an abnormally high voltage signal. This indicates either a short to voltage, sensor failure, or wiring issue preventing proper variable intake manifold operation.
Common Causes
35%
Faulty IMT valve position sensor
30%
Wiring harness short to voltage or damaged connector pins
20%
Corroded or damaged sensor connector causing poor ground
10%
Failed PCM internal circuit or driver
5%
Broken or binding IMT valve actuator causing abnormal feedback
Diagnostic Steps
1
Step 1: Inspect the IMT valve position sensor connector for corrosion, damage, or moisture and repair as needed
2
Step 2: Check sensor voltage at rest and during commanded operation using live data; should read 0.5-4.5V depending on position
3
Step 3: Disconnect sensor and measure reference voltage (typically 5V) and ground circuit integrity at the harness connector
4
Step 4: Test sensor resistance according to manufacturer specifications and compare to known-good values
5
Step 5: If all circuits and sensor test normal, suspect PCM issue or mechanical binding of the IMT valve preventing proper operation
Estimated Repair Cost
$150 - $600
Parts + labor, varies by vehicle and location
The intake manifold tuning valve position sensor circuit on Bank 2 is reading an abnormally high voltage signal. This indicates either a short to voltage, sensor failure, or wiring issue preventing proper variable intake manifold operation.
The most common cause of P207D (Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit High Bank 2) is: Faulty IMT valve position sensor
Typical repair costs for P207D range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive but may experience reduced power, poor fuel economy, and rough idle. Performance will be noticeably diminished especially at higher RPMs.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P207D to identify the root cause.
