You can go to any Autozone, Advance Auto Parts or Pep Boys store and ask to have your check engine light diagnosed for free. They have an electronic scanner that does the job.

And don't call your car "stinking"; you should be proud that the ES has reached at least 200K on the odometer. Goes to show you how reliable and long-lasting your car has run

I did it myself, but I read somewhere it may only be possible with California models.
However, for a 93, mine was originally bought in NY and it still worked.
The California thing might be for the newer models.

You can check it yourself, all you need is a jumper wire.

EI and TEI terminals on your diagnostics 1.

Its under the hood, passenger side by the front struts.
Its a small rectangular black plastic box. Pull the cover.

E! and TEI is on the left set of terminals.
There should be nine terminals on the left side.
E! is the top right
TE 1 is the one in the center.
The inside of the cover you opened should have a diagram.


With the car turned off, put the jumper wire in.
Turn key to on but do not crank the engine.
Check engine light will start blinking.
Count how many times it blinks, there will be a set of blinks , a short pause, then a few more.
Then a longer pause, and the new set of codes will start blinking.
Have a pen and pad ready to take down the number of blinks

I had code 52 and 55 which are knock sensors.
5,21,27,28 are oxygen sensor related.

Also, troublecodes.net is a good website to check out, thats where I got this info.
This will save you a trip to a diagnostics scanner.

A jumper wire is just a short piece of electrical wire or anything metallic tha will complete a circuit.
A paper clip will work but it wont be as secure as electrical wire.
Dont worry about the grease, its normal

The codes will erase when the batttery is dead or pull a certain fuse. If the condition still exists, it will eventually come back. If it doesnt come back, youre set.
