I already know what to about this one

P1565
Speed control commanded switch out of range high/fault in cruise control circuit feeling this one is related to the misfire

P1246
generator load output condition
this is the alternator because im getting check charging system light

P1000
was told computer saying there is no CEL light on but it is
so im guessing something needs to be reset i did put in a new battery because of the check charging system light

C1236
wheel speed left rear input signal missing
help with this one

C1805
pcm and or abs module mismatch
help with this one

U1262
standard communication protocol/communicaation bus malfunction

havent started looking for the answer to my problems yet will do when i get home any info will be appreciated

Start by taking care of the Alternator issue. If there is a voltage supply problem to the ECM and any related components, you can get all kinds of goofy things going on...electronics are sensative to voltage/amperage.

Once that is taken care of, clear the codes and see which ones return. I'd suspect the only to return would be C1236 and P0304, but maybe not even P0304 because the COPs also depend on appropriate voltage signal from ECM.
 
P0304 - Probably time to replace all the COPs and spark plugs. Do this before you are also replacing the catalytic converters.

P1565 - Your clockspring is starting to fail. Eventually your radio controls and airbag will fail too.

P1246 - Probably time for a new (rebuilt) Ford OEM alternator.

P1000 - The PCM hasn't had time to complete all its emissions diagnostics since the last time you disconnected the battery. It's a warning to the test folks that you reset the check engine light to try and pass the emission test. It will clear if you leave the battery connected and drive it long enough.

C1236 - Your rear driver's side wheel speed sensor is bad, or the wiring to it is. It's usually the sensor assembly.

C1805 - Have you recently changed the ABS module? It hasn't been configured correctly for your car.

U1262 - Normally you can ignore this one, but you can't. You've reset all codes recently (see P1000), and yet this one is already back. You have a wiring fault on the data bus somewhere. It could be because of COP #4. C1805 could be coming from that too.

There are no low voltage codes, so probably none of these codes came from the alternator issue, except for P1246.
 
Ill start with the alternator, COPs and plugs and see what that does.
I haven't changed the ABS module only thing i changed was the battery since ive had the car because the check charging system light which goes away after it comes on twice . All these codes came on all at one time that was about a week ago haven't drove it since then until today to find out why they came on.

You may or may not have needed a new battery. However be aware that the charging system light does not come on for battery problems. It only comes on for charging system (usually the alternator) problems.
 
Yeah i figured that a lil while after i changed the battery but my mazda was having alternator/battery problems at the same time so i was trying to prevent having to do the same with the ls.

I'm driving '01 v8 a lil under 140k is there any other things i can do on the preventive maintenance side of things while i get this CEL stuff handled?

Cooling system.
Also, be sure to replace all COPs and spark plugs as mentioned.
 
Joe out of all the codes which ones do you think would get the CEL off?

While there are no codes for low voltage, inadiquate voltage or amperage to/from sensors and electronic components can create false readings to/from the ECM which can "falsely" trigger codes. It is very simular to having a bad ground, which will also cause various electronic anomolies.

I doubt it is coincidence that all 8 codes set at the same time from individually failing components...they all have one thing in common...the need for adiquate power.
 
Maybe this will help when i get someone from autozone to check the voltage it reads around 13.3 if im remembering correctly and they say thats fine should it be higher than that

That's not fine, it should be ~14.4. You need a new alternator.
 
Ok ill pick all the parts i need plugs, COPs and an alternator. Ill do just the alternator first and see what that does. Hopefully it will make everything right so i can have peace of mind.

Voltage is one thing, amperage output is another...
 
C1236 code ...........
Normal Operation
The wheel speed sensor and sensor ring generate a square wave signal to the ABS module that is proportional to wheel speed. The ABS module compares wheel speed inputs from all wheel speed sensors to determine an impending wheel lockup.

Possible Causes
Mismatched tire sizes.
Wheel speed sensor ring.
Wheel speed sensor.
ABS module.
