What Does P2076 Mean?
The PCM has detected that the intake manifold tuning valve position sensor on Bank 1 is reading values outside the expected range for the commanded position. This indicates a performance problem where the sensor feedback doesn't match what the valve should be doing.
Common Causes
35%
IMT valve stuck or binding mechanically due to carbon buildup or debris
30%
Failed or degraded IMT valve position sensor
20%
Faulty IMT valve actuator motor or solenoid
10%
Vacuum leaks affecting IMT valve operation
5%
PCM software issue or calibration problem
Diagnostic Steps
1
Step 1: Monitor live data for IMT valve commanded position vs. actual position sensor reading
2
Step 2: Manually inspect IMT valve for binding, carbon buildup, or mechanical restriction
3
Step 3: Test IMT valve actuator by commanding it on/off with scan tool bidirectional controls
4
Step 4: Check vacuum supply to IMT valve (if vacuum-operated) and test diaphragm integrity
5
Step 5: Verify position sensor voltage/resistance specifications and compare to actual readings
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 1 is reading values outside the expected range for the commanded position. This indicates a performance problem where the sensor feedback doesn't match what the valve should be doing.
The most common cause of P2076 (Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Range/Performance Bank 1) is: IMT valve stuck or binding mechanically due to carbon buildup or debris
Typical repair costs for P2076 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 may experience reduced power, poor fuel economy, and rough idle. Engine performance will be compromised, especially at certain RPM ranges.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2076 to identify the root cause.
