⁽¹⁾	Some DTCs are two-trip detection logic DTCs. For more information, see TWO-TRIP DETECTION LOGIC under SELF-DIAGNOSTIC SYSTEM.

⁽²⁾	These DTCs are for models equipped with engine immobilizer system. MIL will not illuminate. For diagnosis and testing procedures, see appropriate ENGINE IMMOBILIZER SYSTEMS article in ACCESSORIES & EQUIPMENT.

⁽³⁾	See DIAGNOSTIC TESTS in SELF DIAGNOSTICS - CAMRY - 4-CYLINDER (EXCEPT PZEV) article.

⁽⁴⁾	This DTC is recorded when the air-fuel ratio (A/F) sensor is a malfunction, although the detection item is oxygen sensor.

⁽⁵⁾	If this DTC is set, ECM will enter fail-safe mode.

⁽⁶⁾	The malfunction indicator light (MIL) will not illuminate

⁽⁷⁾	This DTC indicates a malfunction related to primary circuit.

⁽⁸⁾	Refer to DIAGNOSTIC TESTS in appropriate DIAGNOSIS article in TRANSAXLE/TRANSMISSION.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
