14

Ignition Signal

No IGF signal to ECM for 4~7 consecutive IGT signals with engine speed less than 3,000 rpm.

Open or short in IGF circuit from igniter to ECM
Igniter
ECM

ONn/a

Yes

It seems you may have a problem with your igniter. Did you ever get a TSRM for your Supra?

Also, please re-check those codes. I don't think it's possible for the ecm to give a single-digit code. Perhaps it's 22?

hi mate, but if it's code 22, should the time gap of those flash a bit longer? I did upload to youtube, would you mindhave a quick look for me?

To me, it looks like codes 14, 21, and 42. Can you continue the video longer? There is a HUGE pause when the cycle of codes ends...

Yep it's codes 14 and 42 for sure. The TSRM will help you to diagnose each code. This isn't 'rocket science' or voodoo. Each code has a series of troubleshooting steps, detailed in the TSRM, that will always resolve the code. Think of it this way - even a high-school graduate Toyota mechanic has to be able to follow the instructions! :) No slam against high school grads at all - I often wish I had a job that let me get outdoors or get some exercise during the day instead of being stuck behind a desk.

14 is your "Ingition Signal" (not necessarily your igniter). It could also be an open or short in the circuit, or a problem with the ECM itself. You'll likely have to diagnose the problem with a multimeter.

...and 42 is a problem with your "No. 1 Vehicle Speed Sensor" (or the electrical connection to it from the ecu). Replace the sensor and/or troubleshoot the wiring with a multimeter.

Again, get the TSRM!!! It'll save you time and $$$. Really!

finally fixed the problem.
it casued by the starter...but the car give me a code 14..:werd:
anyway.. thank you everyone

Thank you for posting back with your result, and congratulations on solving the problem!

Same thing on 1993 supra TT

Im getting codes 14 and 42 also. Car goes into safe mode and runs but with no power and misses awful if u step on the gas to much. You say you replaced the starter?????????????? and that fixed it? please confirm this for me as I can get to work on that. Thanks
