Toyota Camry · 2022–2024
Toyota Tech Tip T-TT-0733-23 applies to some 2022-2024 Camry and Camry Hybrid vehicles with an A25A engine water-pump leak and/or an illuminated MIL with P26CA14 or P26CA31. Toyota asks technicians to document the pump and electrical connectors and contact Technical Assistance through a TAS case before diagnosing or repairing the vehicle. The Tech Tip does not extend the condition to 2018-2021 Camry vehicles and does not identify a replacement pump, gasket, coolant, or universal repair.
Common Symptoms
- Engine water-pump coolant leak
- Malfunction indicator lamp
- Stored DTC P26CA14 or P26CA31
How to Fix
Record the exact DTC suffix and freeze-frame data, inspect the engine water pump and connector area without erasing evidence, and take clear photographs of the pump and electrical connectors. An authorized Toyota technician following T-TT-0733-23 should create a TAS case and contact TAS before diagnosis or repair. Follow the resulting case direction and current repair information; do not order pump 16032-F0011 or any other part from this card because the Tech Tip does not prescribe one.
Owner tips & cautions
- TipPreserve the exact code suffix and freeze-frame data and photograph the pump and connectors before evidence is cleaned or codes are cleared.
- WarningT-TT-0733-23 requires Toyota TAS contact before diagnosis or repair and does not authorize a specific pump or part number; do not parts-cannon this condition from a generic search result.

Frequently asked questions
What does P26CA mean?
P26CA stands for "Engine Coolant Pump Control Circuit Malfunction." The ECM calculates required coolant flow from engine coolant temperature, engine speed, and vehicle speed, then commands the electric engine water pump accordingly and monitors its feedback. P26CA sets when that control circuit or feedback is wrong. Toyota's Tech Tip T-TT-0733-23 identifies the two sub-codes seen on A25A engines: P26CA14 'Engine Coolant Pump Circuit Short to Ground or Open' and P26CA31 'Engine Coolant Pump No Signal' (P26CA12 is short to battery). On A25A-FKS/FXS engines these codes commonly accompany a physical coolant leak from the water pump itself.
What are the most common causes of P26CA?
The most common causes of P26CA are: Electric engine water pump internal failure, Coolant leaking from the water pump into the pump's electronics/connector, Open, short-to-ground, or short-to-battery in the water pump control circuit wiring, Corroded or water-intruded water pump connector, Blown fuse or ECM driver fault. The specific cause varies by vehicle.
How much does it cost to fix P26CA?
Repair costs vary widely depending on the root cause and vehicle.
