figured out how to get the check engine light to flash codes, anyone know where to find what they mean?

Question

1991 z-24

Answer 1

Since you don't have any contact info, I have no other choice.


In refernece to http://answers.yahoo.com/question/index?qid=20061014122159AAFpum3&r=w#NbUvWju8VzmdRHfXRHQU


Yes, it does depend on how they are hooked up.

If your subs are wired in PARALLEL (that all (+)'s wired together as well as all (-)'s wired together), then the resulting impedance will be 2 ohms ONLY IF both subs are 4 ohms each.

Wired in series, the resulting impedance will be 8 ohms. This WILL NOT hurt your amp, but the output power will be cut in half.

Here is the difference:

To calculate for this type of connection, just add the ohms of the subs (or coils) together.


Parallel connection

This ones a little tricky to calculate, this is the formula. Z = total impedance (ohms), sub# is each subs (or coils) value.

Z = 1 (1/sub1 + 1/sub2 + 1/sub3 + ...) to as many as you have

To get best performance, match the watts RMS between amp and sub(s).

Answer 2

Reading the code is not really what was wrong.
Take it ti Auto_Zone and thy will run the code for free and tell you what is wrong.
It's free and you can get the replacement part there to.
PS Don't forget to have them cancle the code after you repair it.
If you dont reset the computer putting in the new part will not fix it. The computer will think the old part is still installed and the light won't turn off.

Answer 3

Do a search for GM TDC codes. Being a 1991 you will most likely be looking at a three digit code.

NOTE----->

Always keep in mind that the code(s) stored in the PCM represent faults or failures in the system or circuit, and NOT NECESSARILY a failure of a specific component. It will be important where your time, effort, and money are concerned to diagnose and repair the circuit rather than just throwing parts (pronounced MONEY) at the car.

Good Luck
