Odd 1993 codes

This is strange i have more codes in my computer then i could imagine!!!!
I used this code pulling technique
http://www.freeautomechanic.com/diagnostictroblecodes4.html
Then i found these codes.
9,15,17,23,24,26,34,69
9-Engine Coolant Sensor
15-Left Heated O2 Sensor Volt Below 0.55v
17-Left heated o2 senor does not change
23-Right O2 sensor Volt below 0.55v
24-Right o2 sensor volt not changing
26-Canister Purge Solenoid
34-Idle air control solenoid
69-Cooling Fan Engine Coolant Temperature Sensor

Now i am dumbfounded due to how well the car runs!
i am wondering? is there a ground wire issues with these vehicles that could cause ALL this? or is it possible it could still run great with all thses codes/problems?
I love my car but i hate my issues

i had the same trouble with my 93. i had to clear all the codes and then start the car and run it until the check engine light came back on. then check the codes again.

Hi there!!

Best thing to do is reset the codes.
You don't need to leave the battery off for five mins, but you do disconnect it. Then just press the brake pedal for about 30 seconds, and that should do it.

Pull the codes again to see if they've cleared, and after that, take her for a short spin.

Pull the codes again and see what shows up.

If you want to check earth wires, check the main earth cabling, but if you look down below the battery tray near the engine mount you'll see a white multi-plug type thing with several black wires coming form it - this is a ground point for several sensors, and worth checking.

Hope you get it sorted!! :)
