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.

    1. You have your paper clip plugged into the wrong terminals; try terminals TE1 & E1. You should get. 71 trouble code indicating a problem with the erg system.

    1. Chansa-

      I’m not sure, but I think ABS should reset itself? If not, you’ll have to use the scantool. If it still doesn’t clear, then replacing the sensor may have not addressed whatever the controller is seeing or not seeing. Which YMM and DTC?

      Year, Make, Model, and how are you extracting codes? I’m guessing by flashing the check engine light? The more information you can give us, the better chance we have of helping you out =)

  7. I have the 95 Camry 3.0L V6. I’ve tried to use a paperclip to jump TE1 and E1 in the diagnosis box but nothing happened. I can only assume it’s because this specific vehicle is exclusively OBD2 compliant. Will go to O’Reilly’s tomorrow to have this checked.

  8. I have a 1996 Toyota Dyna (BU102) 4.1 litre diesel (15B-487957) 24v light truck. When you put it in either first or reverse gear the engine warning light will flash on and go out then flash back on and so on. It doesn’t do it in any other gears and the truck runs fine. Have flushed the engine and replaced anti freeze, replaced the temperature water sensor, replaced the alternator, fitted new batteries, bought chocolates for the wife but the dam thing keeps doing it. Completely at a loss. Can you offer any advice please.

    When I floor the gas pedal instead of the car kicking on it holds back and more of the engine can be heard than the car gathering speed as soon as u release the pedal it kicks of again

    1. I’d first check that the shift solenoids are all functional and transmission fluid is at the proper level. Do you have any DTCs? If the transmission isn’t shifting into overdrive, this could indicate a shift solenoid problem or a fluid level problem. Even if overdrive works, shifting into overdrive, it might be engaging slower than the controller is expecting, which it detects as a fault.
      On your rig, both solenoids are OFF for overdrive.
      1st Gear S1=ON/S2=OFF
      2nd Gear S1=ON/S2=ON
      3rd Gear S1=OFF/S2=ON
      4th Gear S1=OFF/S2=OFF
      This might not be an electrical problem (wiring or solenoid), but a hydraulic problem. I recall a hard-to-find issue with the check-ball on one of the accumulator circuits. The seat was deformed so the check-ball wouldn’t seal properly. The accumulator wouldn’t build pressure fast enough, setting off a solenoid code.

  42. question I have a trouble code of PO500 which according to your codes is the vehicle speed sensor. The speedometer does not work and the check engine light is on. Toyota tells me that there are 2 speed sensors on the tranmission and 2 each on each wheel on my 2004 Toyota camry 2.4 litre engine. My friends scanner says po500 speed sensor A is the problem but where is it on the transmission? and is there a way to tell which one to change. This problem occurred after going through heavy rainfall and I found the ground was corroded at the negative battery post and it blew gauge 1 fuse which I repaced. Any help would be appreciated
