Electric/Auxiliary Transmission Fluid Pump Motor Phase W Current

Where it lives

For P0B06, the part to look at first is the pump named here.

Check these first

• A short or open in the phase W wiring harness
• Corroded phase W pump motor connectors
• A failed auxiliary transmission fluid pump motor
• Low battery voltage at the pump motor

What to do next

1. Read the transmission fluid pump phase W current on a scan tool
2. Check the phase W harness for a short or open
3. Measure the phase W winding resistance
4. Check the battery voltage
5. Replace the pump motor if the circuit tests good
6. Clear the code and retest
