What Does P207C Mean?
The PCM is detecting an abnormally low voltage signal from the intake manifold tuning valve position sensor circuit on Bank 2. This indicates a short to ground or internal sensor failure.
Common Causes
35%
Wiring short to ground in Bank 2 IMT sensor circuit
30%
Failed Bank 2 IMT position sensor with internal short
20%
Corroded or damaged Bank 2 sensor connector
10%
Chafed wiring harness on Bank 2 side of engine
5%
PCM internal fault in Bank 2 sensor circuit driver
Diagnostic Steps
1
Step 1: Check voltage at Bank 2 IMT position sensor connector with key on (expect ~5V reference)
2
Step 2: Inspect Bank 2 sensor connector for corrosion, moisture, or physical damage
3
Step 3: Backprobe sensor signal wire and test for short to ground using multimeter
4
Step 4: Disconnect sensor and verify signal wire shows infinite resistance to ground
5
Step 5: Test sensor independently with external power supply to verify internal condition
Estimated Repair Cost
$150 - $600
Parts + labor, varies by vehicle and location
The PCM is detecting an abnormally low voltage signal from the intake manifold tuning valve position sensor circuit on Bank 2. This indicates a short to ground or internal sensor failure.
The most common cause of P207C (Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Low Bank 2) is: Wiring short to ground in Bank 2 IMT sensor circuit
Typical repair costs for P207C range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive but Bank 2 will operate with fixed intake configuration. Performance degradation and fuel economy loss will be noticeable, particularly in V-engines.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P207C to identify the root cause.
