Owners of certain 2021-2022 Toyota vehicles, including the Toyota Camry, equipped with A25A-FKS, A25A-FXS, or M20A-FKS engines, may experience an 'Oil Pressure Low' warning message. This condition is detailed in Technical Service Bulletin (TSB) 10206528, which outlines the cause and recommended repair procedures for this issue.
Symptoms
Drivers may notice one or more of the following indicators related to the Toyota Camry oil pressure low condition:
- Milky/Discolored engine oil: The engine oil may appear cloudy or discolored, indicating moisture contamination.
- "Oil Pressure Low" warning message: An explicit warning message will display on the Multi-information Display (MID).
- MIL ON condition: The Malfunction Indicator Lamp (MIL), also known as the Check Engine Light, may illuminate.
Fault Codes / DTCs
When the MIL is illuminated, diagnostic trouble codes (DTCs) related to engine oil pressure may be stored in the vehicle's computer system:
| Code | Description |
|---|---|
| P05202A | Engine Oil Pressure Sensor/Switch "A" Signal Stuck in Range |
| P052477 | Engine Oil Pressure too low [Severe] |
Diagnosis / Trigger Conditions
This issue primarily occurs in extreme cold weather conditions. Moisture from blow-by gases can condense and accumulate in the engine oil, especially during short trips where the engine does not reach full operating temperature. When this moisture freezes, it can lead to a drop in oil pressure, triggering the warning messages and DTCs.
Repair Procedure Summary
Toyota has issued TSB 10206528 to address these specific conditions. The bulletin provides detailed procedures for technicians to diagnose and resolve the issue. While the exact steps are for dealership technicians, the general approach involves addressing the moisture accumulation and ensuring proper oil pressure. Owners should consult with a certified Toyota service center for diagnosis and repair.
Owner Action
If you own a 2021-2022 Toyota Camry or another affected model and experience any of the symptoms mentioned, such as milky engine oil or the Toyota Camry oil pressure low warning, it is important to have your vehicle inspected. Contact your authorized Toyota dealership to schedule a service appointment. They will be able to diagnose the issue using the guidelines provided in TSB 10206528 and perform the necessary repairs to restore proper engine function.
