MX-3.com

Ok so ever since I bought my 1992 SOHC the CEL has been on, I have had it checked acouple of times and it's a code three. (No G signal) I have searched and not found anything. They said to me you would usaully get a code 1 or 2 before three. And they said if it is doing anything it would be poor performance and gas mileage. I have only been getting 200 to 215 miles on a tank lately, not good for a SOHC. I replaced my O2 sensor, and it helped for about a tank of gas. I got 315 the day i replaced my o2 sensor. What would I have to do to fix a code three (no G signal)?

Have a look here:

Its got step by step procedures to rectify the problem.

code three says in the manual

G-signal (DOHC and Calfornia B6) location of malunction

Fail safe/ Cancels 2- group (DOHC) or sequential ( California B6) injection

not to sure what that mean could be injecters or something else

Just in case you didnt notice Limegreen.. The online shop manual is for a 95 MX-3.. hence the DOHC.. and his is a 92 SOHC.. the codes can be different (though not always).. and yeah.. I have made that mistake a couple of times myself LOL

So... Since that was for the DOHC and mine is SOHC, is there that much different? I mean there has to be someone that has had this problem that has fixed it...

Reset ur ECU (disconnect battery for a couple of minutes. Negative side), hold brake for a bit in that time.

If the code comes back try, replacing ur cap and rotor (cheap).

But I'm sure somebody else knows for sure.......................

good luck

Ok just for giggles i checked it again, definalty code 3, which is no g signal. But what is that, I've heard it's inside the disturbutor and can affect performance and mileage, well it is affecting those both. I just want to know how to fix it, new dizzy, cap and rotor, maybe some wires are bare and need coverd? I dunno. Help me out. Its a SOHC so i dont know if the PDF Grants sent me will work.

I am just wondering if anyone has anymore info on this problem. i just sold my 5.9 v8 Dodge Ram and now im back into my old mx-3 1.6 sohc.

After sitting for a year, the thing fired right up. However, i am still getting a CEL code 3.

i changed the distributor just last year and replaced the cap and rotor yesterday.

Any solutions??? thanks !

Try following the wires on the distributor and seeing if there's any bare wire and also clean the grounds, they can cause alot of problems with these cars. There's one that bolts to a small bracket on the trans that can cause alot of trouble, the easiest way to fix that one is to bolt it directly to the trans without the bracket. Check your coil wire too, it's possible a weak spark could trigger it as well. Just spray the wire at night and if you see sparks or the car starts to sputter, you need new wires.
