P2601 on Porsche
Coolant Pump "A" Control Circuit Range/Performance
P2601 on Porsche vehicles indicates coolant pump "a" control circuit range/performance. Au7o has documented this code across 1 Porsche model — most commonly on 718 Boxster. The PCM detects that the coolant pump 'A' control circuit is electrically intact but the pump is not responding as expected — the measured behavior is out of the normal operating range (e.g., commanded flow/voltage doesn't produce the expected result). This points to a marginal/degraded pump or circuit rather than a hard open or short. Typical repair costs on Porsche range from $800 to $2,500, depending on the specific model and root cause.
Common Causes of P2601
- •Worn or seizing electric coolant pump
- •High resistance in the pump wiring or connectors
- •Restricted coolant flow / air-bound cooling system
- •Intermittent pump or relay operation
- •PCM control-circuit performance fault
P2601 on Porsche by Model
Porsche 718 Boxster(1 issue)
- Cooling System Changeover/Bypass Valve and Water Pump Failure Causing Overheating2017-2021
The 718 Boxster's pressure-charged flat-four runs a complex cooling circuit with electrically actuated changeover (bypass) valves and a coolant-pump assembly that is prone to faults. Owners report an 'Engine over temp. Park vehicle to cool down' dashboard warning and erratic temperature-gauge behavior, often appearing after spirited driving or on hot days when the turbocharged engine demands extra cooling. Root causes include sticking/failing coolant changeover valves, a failing main water pump (early bearing wear, plastic-impeller degradation), and leaking coolant covers, sometimes escalating from a fault stored in the cooling-management module. This is distinct from coolant seepage at the turbo connections.

What does P2601 mean on Porsche?▼
P2601 stands for "Coolant Pump "A" Control Circuit Range/Performance." The PCM detects that the coolant pump 'A' control circuit is electrically intact but the pump is not responding as expected — the measured behavior is out of the normal operating range (e.g., commanded flow/voltage doesn't produce the expected result). This points to a marginal/degraded pump or circuit rather than a hard open or short. On Porsche specifically, this code is documented across 1 model.
What causes P2601 on Porsche vehicles?▼
Common causes on Porsche: Worn or seizing electric coolant pump, High resistance in the pump wiring or connectors, Restricted coolant flow / air-bound cooling system, Intermittent pump or relay operation, PCM control-circuit performance fault. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2601 on a Porsche?▼
Repair costs on Porsche range from $800 to $2,500, depending on the specific model and root cause.
Which Porsche models have P2601 documented?▼
