Starter/Generator Phase Z Current Sensor Circuit Low

Where it lives

For P2D97, the circuit described runs through the sensor. The description of P2D97 reports a fault at the sensor.

Check these first

• A short to ground on the starter/generator phase Z current sensor wire
• A failed phase Z current sensor
• Corrosion at the phase Z sensor connector
• A faulty inverter current input
• A chafed phase Z harness

What to do next

1. Read starter/generator phase Z current on a scan tool
2. Inspect the phase Z sensor wire for a short to ground
3. Check the phase Z sensor connector
4. Test the phase Z current sensor
5. Replace the sensor if the current stays low
6. Clear the code and retest
