What Does the P2600 Code Mean?
OBD-II Code P2600 is defined as a Coolant Pump “A” Control Circuit/Open. This code is triggered when the Powertrain Control Module (PCM) detects that the electric coolant pump is not operating as expected, which can affect the vehicle’s ability to heat efficiently before engine start.
What Causes the P2600 Code?
The P2600 code can be caused by several issues, including:
- Coolant Heat Storage (CHS) water pump failure
- Coolant Heat Storage (CHS) water pump relay malfunction
- Powertrain Control Module (PCM) failure
- Wiring issues within the coolant pump circuit
What Are the Symptoms of the P2600 Code?
When the P2600 code is triggered, you may experience symptoms such as:
- Check Engine Light (CEL) illuminated
- Engine overheating
- Poor engine performance
- Increased fuel consumption
How Serious Is the P2600 Code?
