Trouble Code Definitions/Charts: Notes
Toyota does not have step-by-step trouble charts like many other manufacturers. The following two illustrations contain ALL the trouble code definition/troubleshooting information released. No other specific information is available.
The illustrations will identify possible "Trouble Areas" for any given code. It is one of these "Trouble Areas" that is likely causing the fault.
After defining the applicable codes and "Trouble Areas", proceed to the TROUBLESHOOTING AIDS section for assistance in diagnosing the trouble code fault.
NOTE:
For definitions of the circuit labels (like "IGf", "Ne", "IDL", etc.), refer to the WIRING DIAGRAMS - 4-CYL EFI
article in this section.
