Toyota AVALON CAMRY SOLARA ECHO SIENNA 1994 – 2009 OBD2 Trouble Codes list
OBD2 trouble codes are diagnostic codes that are used to identify issues with a vehicle. These codes are generated by the onboard computer system of a vehicle and can be read using an OBD2 scanner. The Toyota Avalon, Camry, Solara, Echo and Sienna from 1994 to 2009 have some common OBD2 trouble codes such as P0100, P0101, P0102, P0103 and P0104. These codes are related to the mass or volume air flow circuit malfunction, range/performance problem, low input, high input and intermittent issues respectively.
It is important to note that OBD2 codes can be generic or manufacturer-specific. If the first two characters of the OBD code are P0, P2, P34-P39, B0, B3, C0, C3, U0 or U3, the issue is generic. If they are P1, P30-P33, B1, B2, C1, C2, U1 or U2, the problem is manufacturer-specific.
I hope this helps. Let me know if you have any other questions or requests.
