Gate Select Actuator Circuit Low

Where it lives

For P0912, the circuit described runs through the actuator. The description of P0912 reports a fault at the actuator.

Check these first

• A short to ground in the gate select actuator circuit
• A chafed gate select actuator wire
• A weak battery dragging the actuator circuit
• A failed gate select actuator coil

What to do next

1. Read gate select actuator voltage on a scan tool
2. Test the gate select actuator circuit for a short to ground
3. Check the battery voltage and charging
4. Measure the gate select actuator resistance
5. Replace the actuator if the coil is shorted
6. Clear the code and retest
