Q: What does code P1229 mean?

Intercooler Pump Driver Fault. P1229 on Ford vehicles indicates that the powertrain control module (PCM) has detected a fault in the intercooler pump driver circuit, which is responsible for operating the pump that circulates coolant through the intercooler system. The PCM monitors the driver output for expected voltage or current feedback and sets this code when the signal is outside the expected range, often due to an open, short, or excessive current draw.
