What does P2B67 mean?
Coolant pump D reports a control circuit low condition. Coolant circulation through the affected loop cannot be commanded reliably.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Control wire shorted to ground
- Medium Internal short in pump motor
- Low Connector pins corroded - high contact resistance
Likelihood is a general estimate across vehicles; your make and model may differ.
Add your car to see reports of P2B67 on the same make and model first.
