Service Bulletins

Toyota Camry Misfire DTCs in Cold Temperatures

Toyota issued Technical Service Bulletin T-SB-0010-24 Rev2 to address a common issue where various models, including the Toyota Camry, might display a 'MIL ON' (Malfunction Indicator Lamp illuminated) condition accompanied by misfire Diagnostic Trouble Codes (DTCs) when operating in cold temperatures. This bulletin outlines a repair procedure that often involves the replacement of exhaust manifold components to resolve the misfire DTCs. Owners experiencing this specific problem, especially in colder climates, should be aware of this bulletin.

"Engine Maintenance Required" with DTCs P268111 or P268115

Another significant communication is Technical Service Bulletin T-SB-0112-24 Rev2, which targets certain 2018-2021 Toyota models. These vehicles may display an "Engine Maintenance Required" message on the dashboard, often accompanied by Diagnostic Trouble Codes P268111 or P268115. This TSB details the procedure to address issues related to the Engine Coolant Bypass Valve, which can trigger these warnings. Addressing this promptly can prevent further engine-related complications.

Musty Odor Remediation

For a more comfort-oriented concern, Toyota Technical Service Bulletin T-SB-0055-24 Rev2 provides a solution for musty odors in 2021-2026 Toyota vehicles. These odors are often a result of water intrusion within the vehicle's climate control system. The bulletin outlines a comprehensive dealer-performed remediation process, which includes inspection, thorough cleaning of affected areas, and an ozone treatment to eliminate the persistent musty smell. This is a common complaint that can significantly impact the driving experience.

Navigation Map Update Process

Toyota also released Technical Service Bulletin T-SB-0001-26, detailing the Premium Audio Navigation Map Update Process for 2018-2024 vehicles. This bulletin provides instructions on how to update navigation maps, points of interest, and system software using a Special Service Tool (SST) USB flash drive. This update is crucial for owners who rely on their vehicle's built-in navigation system for accurate and up-to-date information.

Low Oil Pressure DTCs P05202A and P052477

An important bulletin, T-SB-0104-21 Rev2, though now superseded by a Lexus bulletin, previously addressed issues in certain 2021-2024 Toyota models, including the Toyota Camry, related to low oil pressure. Owners might have observed a 'MIL ON' (Malfunction Indicator Lamp illuminated) and Diagnostic Trouble Codes P05202A or P052477. This issue was particularly noted in freezing temperatures, sometimes accompanied by milky or discolored engine oil. While this specific bulletin is obsolete, the underlying concern of low oil pressure and its associated DTCs remains critical for engine health.

MIL ON with Throttle Body DTCs P01201C, P210015

Toyota's T-SB-0005-24 Rev2 addresses instances of Malfunction Indicator Lamp (MIL) illumination and reduced engine power in 2021-2022 Toyota Avalon, Camry, and RAV4 vehicles. This problem is linked to specific throttle body Diagnostic Trouble Codes (DTCs) such as P01201C, P210015, P210019, and P211172, often triggered in freezing temperatures. The bulletin outlines an ECM (Engine Control Module) update as the necessary repair to resolve these throttle body-related issues and restore full engine performance.

Coolant Leak Customer Support Program 24TE04

Toyota has also initiated Customer Support Program 24TE04 to address a potential flow shut-off valve coolant leak. This program covers certain 2019-2021 Avalon, Camry, Corolla, Highlander, RAV4, Sienna, and Venza models. A coolant leak in this area can manifest as an "Engine Maintenance Required" warning message or even impact the functionality of the air conditioning system. Under this program, Toyota will cover the necessary repairs, providing relief to owners facing this issue. This is a significant program as it directly covers repair costs for affected vehicles.

What Toyota Owners Should Do

• If your Toyota vehicle is experiencing a 'MIL ON' with misfire DTCs, particularly in cold weather, inquire with your dealership about Toyota Camry misfire DTCs and T-SB-0010-24 Rev2.
• Should your dashboard display an "Engine Maintenance Required" message along with DTCs P268111 or P268115, contact your Toyota service center to discuss the remedies outlined in T-SB-0112-24 Rev2.
• For persistent musty odors in your cabin, especially if your vehicle is a 2021-2026 model, ask your dealer about the remediation process detailed in T-SB-0055-24 Rev2.
• If you've encountered a 'MIL ON' with low oil pressure DTCs like P05202A or P052477, particularly in cold conditions, discuss potential solutions with your service center, referencing the previously issued T-SB-0104-21 Rev2 for context.
• Owners of 2021-2022 Avalon, Camry, or RAV4 models experiencing MIL illumination with reduced engine power and throttle body DTCs (e.g., P01201C, P210015) should consult their dealer regarding the ECM update specified in T-SB-0005-24 Rev2.
• If you own a 2019-2021 Avalon, Camry, Corolla, Highlander, RAV4, Sienna, or Venza and suspect a coolant leak from the flow shut-off valve, inquire about Customer Support Program 24TE04 at your dealership.
• Consider checking with your dealership about the latest navigation map updates, referencing T-SB-0001-26, to ensure your system is current.
