P2B69Coolant Pump D Supply Voltage Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2B69 reports that coolant pump D does not receive a usable voltage on its power feed, as distinct from the control line covered by P2B66 to P2B68. No manufacturer documents this code publicly. Ford shows the same failure type for pump B as P2B62 (type 1C, supply outside its permitted band) and for pump A as P2B9D, each checked continuously above 11 V battery voltage. A blown fuse, a relay that no longer closes cleanly, high resistance at a ground point or a weak battery can cause it, and a voltage drop test under load is the way to find them. Such output components fall within CARB 13 CCR 1968.2 (e)(15). Without adequate power the pump slows or quits, so the circuit it serves overheats more easily.
- What you may notice
- Warning lamp with stored code
- Pump D slow or inactive
- Code returns mainly at low battery voltage or high electrical load
- Likely causes
- LikelyFuse blown or supply relay contacts worn
- PossibleHigh resistance at the pump ground or ground point
- PossibleWeak battery or charging fault
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
