Battery has been disconnected in last 50 starts.

it is a generic code o2 heater (circuit bank 1 sensor 2) usually has to do with an oxygen sensor

p0105 MAF sensor circuit

p0130 02 Circuit malfunction bank 1 Sensor 1

p0150 02 Circuit malfunction bank 2 sensor 1

p1445 not a generic code need vehicle info to gues

All these codes are faulty Circuit codes. So more likly a bad wire, fuse or computer than all the sensors.

Looking at the list I am going to make a guesses starting from most to least likely:

1stThere is a problem with a damaged or broken wiring harnes at the computer. Get a wiring diagram and prove the wiring is good on all the wires to all the sensors on the list

The ECM that runs all this stuff is bad.. Prove the sensors are not bad before replacing an expensive computer.

Next: All these sensors are faulty, crash or used parts or vandalized?

I assume you meant radio error code. -be careful- ... the dealer you got the Honda from will have a code you need to type into the stereo to unlock it. I believe you get six attempts?? .. entering in enough incorrect codes your stereo will litterally melt/self-destruct itself. Get this code from the dealer and store it in a safe place. Anytime you change your battery or the stereo gets disconnected you will need to re-enter that code or you'll junk the radio.

Hope that helps.

Trouble code P1784 means: Pressure switch circuit: LR

The OBD connector is located under the center console on the passenger side. It is OBD-II although not fully compliant.

Error codes are not universal. They vary greatly from one company to another and sometimes even from one product to another within a company, so you need to specify who's product and/or which product is generating the error. It would probably help to categorize the question, too.

Cylinder 5 is missing

It is OBD 1 not OBD 2. The connecter is under the hood, inner fender.
