Q: What does code P2CC9 mean?

Coolant Pump Speed Sensor Range/Performance. P2CC9 indicates that the engine control module (ECM) has detected an out-of-range or erratic signal from the coolant pump speed sensor, which monitors the rotational speed of the electric coolant pump. The ECM compares the sensor signal to expected values and sets this code when the signal falls outside the valid range or does not correlate with other engine data.
