RETRIEVING CODES for vehicles after 96
- 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.
- For an OBD2 code list, please see our Toyota code list or the appropriate generic list.
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.

What is the code 49 in 1az engine 2003
94 Toyota truck 2.422re, code is 31 what do I do
Hi sorry I need know code 26 Toyota Rav 4 1az
26: Air-Fuel Ratio Rich
what is fault code 39
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.
What obd protocol is my truck? It’s not on your list.
Hi I have a 1996 Toyota Crown GS151 and the Engine model is 1gfe 2000cc could you please send me the list of trouble codes,Thankyou
What code are you looking for? That should be OBD2.
Did you see our generic list: https://www.troublecodes.net/pcodes/
Also we have make specific codes that apply to most Toyota vehicles: https://www.troublecodes.net/toyotacodes/
I tried doing that… I then poked the wrong terminal for b , how can i fix my car.. the check engine is now completely of , the change oil now is constantly blinking
PO418 – Hilux Workman ute 2013
My 89 toyota tarago (previa?) seems to be flashing the codes 2 -4, 5 and 11.
It’s symptoms are a lack of usable accelerator peddle travel between deceleration and combustion breakdown. It varies trip by trip but has been getting worse. I doubt the majority of drivers could even pick the sweet spot on a bad day let alone hold it long enough to creep up to 100khr (60mph).
I’ve changed the tps and the Ignition module which had some intermittent broken connection but no luck yet
I’ve bridged te1 and e1 I think that’s what they were and my 1999 Toyota altezza 3sge had the check engine light flashing it was doing 14, 15, 24, 31 any help as I’m lost thanks
#31 is mass air sensor.
I have a Toyota Carina car 1997, 5A engine. I have error code 14, but does these cars have Turbocharger. Also I changed my distributor and still have the same problem. Sometime the car works and another time it shut off while driving, then I have to wait about 15 minutes before it starts, then it will shut down again. Until the next day it will start and work. Please help
Had the same problem with my mercedes – It was a simple fix – an oxygen sensor. < $20 for the part. how to replace it was on youtube.
Why Toyota Innova G 2.5L 2012 is not included in the list.
Hi Danny: We haven’t added some of the newer models yet. Thanks for suggesting the Innova G, and we will prioritize that model for inclusion in the list.
Where on obd2 can I connect a tachometer signal wire the vehicle is fully computerized diesel engine
I love this!!!!
