Dash lights question

[jdm-vr4]

Does anyone know what each wrning light mean on jspec vr4's????

i'm actually after light next to the battery light it looks like steaming muffler or pipe, i think in some cars it means hand brake but it's just what i think.

 

[GVR40]

the handbrake one is and exlamation mark in brackets looks like ( ! ) the one your talking about is for a sensor in the cat convertor, but not sure what it means

thats the cat converter overheat light- when you get an aftermarket exhaust you need to earth the wire or the light will stay on

 

[jdm-vr4]

well i haven't done anything except for puting in differenc ecu with a chip

 

[CLuTZ]

and you're getting which light??


pics?

 

[jdm-vr4]

battery is flat so can't get pics but i get the check engine and that muffler looking light next to battery light(second from left on the rev gauge)

You need to datalog to see what code you're throwing for the CEL- they are a necessity these days!

As for the cat overheat light, well that sounds like a bit of a mystery why thats suddenly decided to go on

 

[jdm-vr4]

i got the code 14, and 25,

so i replaced tps sensor that i got from single cam cyclone engine, and i found that the barometric pressure sensor is in mas so i got a different maf(third one) and i started the car and check engine light came out but i can't log it so don't know what the problem is now.

have you triple checked your wiring to your MAF?

its got to be something simple!

I used the VFAQ as a guide, here's a simplified version that I made:

Now, the only wire that arent marked idetically is 1) Idle position switch on the 1G plug, and 7) Volume air flow sensor reset signal on the 2G plug. These are supposed to be connected together, even though they seem like they do totally different things???


This is the way I did it:

2G-1G
1 - 4
2 - 7
3 - 2
4 - 3
5 - 6
6 - 8
7 - 1
8 - 5
