3S-GTE JDM 3rd Gen Turbo Engine CEL for federal inspection

e30 · 03-04-2009, 05:12 PM

i live in canada and i bought a car from teh states with a gen III swap. the federal inspection needs the CEL to be on when the ignition is on the on position. It has to be also off when the car is started and my car's CEL is not on at all. any ideas?

my other question would be .. does your CEL turn on along with the ABS and brake lights when the key is in the "on" position?

check engine light

wow, missed that one lol,

it's probably just that the wiring wasn't done right when the swap was done. The new engine needs a new ecu right? So the CEL was probably never wired into the new harness when the swap was done.

What year is the car?

or the bulb could be burnt out

Toyota MR2 Message Board 3S-GTE ECU Pinouts

I did a quick search and here's the pinout for the gen3 ecu, the check engine light wire is at the bottom of the page, at pin 16-15, not totally sure how to read the pinouts, but if you trace that wire it (obviously) should head into your cluster, if not, wire 'er in.

its a 91 with a 96 motor and ecu

if you go to a toyota dealer usually they'll pull up the wiring diagram for you, so you can find the check engine light wire from the original wiring set up

thanks for the great info. just wondering if you have a gen III in your car? i noticed that you're located in bc too

I have mk1. I want to swap in a 3sgte though, but it's really looking like it's not going to happen. I kinda like messing with wires, because my last car had issues, it's one big puzzle.

i'm the opposite. i hate electronics lol i like tinkering with the mechanical stuff more

ebouwman · 03-05-2009, 12:57 PM

well i like the problem solving in general, and what's the fun in having a car works properly all the time! LOL

I've definitely learned enough by working on my car to make it more than worthwhile
