Toyota OBD/OBD2 Codes

96 & later are OBD2 systems and require a scantool Note: We are finding that some 94 & 95 Toyota vehicles are OBD2 compliant and require a scan tool. Check your emissions decal under the hood to confirm if you have an OBD2 compliant vehicle.

RETRIEVING CODES for vehicles before 96

NOTE: Not all trouble codes will activate MIL (CHECK ENGINE light)
  • Before proceeding, make sure the:
    • CHECK ENGINE light circuit is functional. It should be ON when the ignition switch is ON with the engine stopped.
    • Battery voltage is above 11 volts.
    • Throttle valve is fully closed (Throttle Position Sensor IDL points closed).
    • Accessory switches (A/C, etc.) are OFF.
    • Engine is at normal operating temperature (if possible).
  • Turn ignition switch to ON position.
    • Do not start the engine.
    • Place a jumper wire across TEl and El terminals in engine check connector.
  • Count number of flashes from CHECK ENGINE light.
    • If system is operating normally (with no detected faults), the CHECK ENGINE light will blink continuouslyand evenly about 2 times a second.
  • Otherwise, the light will blink a number of times equal to the trouble code as follows:
    • The light blinks only (.5 second ON, .5 second OFF) when indicating a number.
    • The light will be OFF for 1.5 seconds between the first digit and the second digit of the code.
    • If more than one code is stored, the light will be OFF for 2.5 seconds before the next code is displayed.
    • Once all code(s) have been displayed, the light will be OFF for 4.5 seconds and then the whole sequence will repeat.
  • The diagnostic code series will continue to repeat as long as the check connecter terminals TEl and El are connected.
  • When finished, remove the jumper wire.
  • After repairing the malfunction, clear the codes from the ECUs memory.

    Clearing Trouble Codes

    All trouble codes must be purged from the ECUs memory after repairing the faults. Otherwise, code(s) would remain in the ECUs memory indefinitely and would appear along with a new code in the event of a future problem.
  • Remove the EFI fuse (15A) for 30 seconds with the ignition switch OFF to clear any codes. It may take longer than 30 seconds, depending on ambient temperature (the lower the temperature, the longer the fuse must be left out).
  • Trouble codes can also be cleared by disconnecting the vehicle battery. However, other memory functions (clock, radio, etc.), will need to be reset.
  • After the codes are cleared, road test the vehicle (as applicable for the fault) and recheck if any codes reset. If so, it indicates that the trouble area has not been repaired correctly.

Reply to  christo

If it’s in the engine controller, code 39 is related to the VVT Actuator. Check the circuit for the VVT Oil Control Valve and the valve coil for continuity.
