What Does P207A Mean?
The PCM has detected a circuit fault with the intake manifold tuning valve position sensor on Bank 2. This is a general electrical circuit malfunction code indicating a problem with the sensor signal, power, or ground.
Common Causes
35%
Failed IMT position sensor on Bank 2
30%
Damaged wiring or connector in sensor circuit
20%
Corroded or loose connector terminals
10%
Open or short in sensor power or ground circuit
5%
PCM fault in Bank 2 sensor circuit
Diagnostic Steps
1
Step 1: Verify proper voltage supply at sensor connector (typically 5V reference)
2
Step 2: Check sensor ground circuit continuity and resistance to chassis ground
3
Step 3: Inspect connector for damage, corrosion, or moisture intrusion
4
Step 4: Test sensor operation by measuring signal voltage through valve movement range
5
Step 5: Check wiring harness for opens, shorts, or damage between sensor and PCM
Estimated Repair Cost
$200 - $800
Parts + labor, varies by vehicle and location
The PCM has detected a circuit fault with the intake manifold tuning valve position sensor on Bank 2. This is a general electrical circuit malfunction code indicating a problem with the sensor signal, power, or ground.
The most common cause of P207A (Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Bank 2) is: Failed IMT position sensor on Bank 2
Typical repair costs for P207A range from $200 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive but Bank 2 cylinders will operate with fixed intake tuning. Performance, fuel economy, and emissions will be negatively affected.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P207A to identify the root cause.
