Intake Valve Control Circuit Low (Bank 2)
Bank 2's intake valve control system isn't getting enough electrical signal to operate properly, like a dimmer switch stuck on low. The engine computer detected the control circuit voltage is below the minimum threshold needed to activate the valve timing solenoid.
The ECM monitors the voltage and current supplied to the intake valve control solenoid on Bank 2. It compares the actual circuit voltage against expected operating thresholds. When voltage drops below the minimum required level, the fault is triggered.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| Solenoid Control Voltage | 11-14.5V at key-on | Below 10V or open/shorted circuit detected |
| Circuit Resistance | 5-8 ohms | Above 15 ohms or below 2 ohms |
Code P0076 is a moderate fault. You can generally drive to a workshop, but avoid long trips or high-load driving (motorway, uphill towing) until it is diagnosed. If the code keeps returning after clearing, or if you notice the symptoms listed above worsening, do not delay professional diagnosis. Many moderate codes have multiple possible root causes — a mechanic with live OBD data can identify the exact fault more efficiently than part-by-part trial and error.
Once the fault is repaired, P0076 can be cleared using any OBD-II scanner. Connect the scanner, navigate to "Clear Codes" or "Erase DTCs," and confirm. The check engine light turns off immediately.
The code will return if the root cause was not actually fixed. The ECM re-detects the fault within 1–3 drive cycles and sets the code again.
