What Does P2565 Mean?
The PCM has detected a voltage signal from the turbocharger boost control position sensor that exceeds the expected maximum threshold. This typically indicates an open circuit, short to voltage, or sensor failure causing abnormally high readings.
Common Causes
35%
Open circuit in sensor signal or ground wire
30%
Failed position sensor with internal open circuit
15%
Short to voltage in sensor signal wire
15%
Corroded or damaged sensor connector with poor contact
5%
Damaged wiring due to heat exposure near turbocharger
Diagnostic Steps
1
Step 1: Disconnect position sensor and check for reference voltage at harness connector (typically 5V)
2
Step 2: Measure sensor output voltage with sensor connected and compare to specifications
3
Step 3: Check for continuity in signal wire from sensor to PCM with sensor disconnected
4
Step 4: Inspect sensor connector terminals for corrosion, bent pins, or damage
5
Step 5: Test sensor across full range of motion if accessible, monitoring voltage output
Estimated Repair Cost
$150 - $650
Parts + labor, varies by vehicle and location
The PCM has detected a voltage signal from the turbocharger boost control position sensor that exceeds the expected maximum threshold. This typically indicates an open circuit, short to voltage, or sensor failure causing abnormally high readings.
The most common cause of P2565 (Turbocharger Boost Control Position Sensor "A" Circuit High) is: Open circuit in sensor signal or ground wire
Typical repair costs for P2565 range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Reduced engine performance and possible limp mode engagement. Safe to drive short distances but repair promptly to prevent potential turbocharger damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2565 to identify the root cause.
