The letters pd probably mean pending. Code 300 is a random miss. Four digit codes are brand specific, code 1305 could be for a problem with the ignition coil or ignitor module. Code 1105 could be for a problem with the MAP sensor or control valve. Other than replacing the spark plugs, you may need to take the car to a shop to get it checked out. Replacing parts without testing first could be a very expensive guess.
The first number is a zero not an "O" P0700 is just the TCM requesting the PCM to turn on the check engine light. Because of these codes are defective transmission wiring harness, defective shift solenoids, defective transmission internal parts.
P2189: Sys Too Lean at Idle Bank2 P2187: Sys Too Lean at Idle Bank1
The other codes P2189PD & P2187PD are pending codes.. Meaning the car will have to recheck the errors before it calls it an error and sets the engine light on. They are the same codes as the others just the PD at the end means pending.
P0146 pd means pending code
Pending codes and DTCs?
Posted on November 12, 2010 by fcrmaster
When reading codes from your vehicle the fault code reader may show them as pending codes or normal Diagnostic Trouble Codes (DTC).
Pending codes (also known as continuous monitor codes) will be registered when an intermittent fault occurs. If that fault does not happen again after x number of start/stop cycles, the ECU will erase the code from memory. If the fault is persistent it becomes a DTC.
If you have read pending codes it is advisable to check the codes again after a week or so. If there is no apparent problem with the vehicle it is safe to erase the codes too and check back. But always make a note of any fault codes with the date and mileage of a vehicle.
If the codes read include a DTC then you need to investigate further. This you can either do yourself or advise your garage. If, again, you don't see an apparent problem (depending n the severity of the code) with the vehicle you can note the codes down and erase them. Then check again after a week or a few days depending on how often the vehicle gets used. If a repair has been made (previous owner) the DTC may just not have been reset after the repair.
The other numbers behind the code 01/06 ,
02/06, 03/06 , 05/06 ,04/06
These don't mean anything . cheap code reader .

Sorry but this is something you should take to a qualified repair shop that has a diagnostic tool that can view sensor scan data. Causes of lean condition trouble codes P0171 P0174 GM 5 3L
your vehicle is driving good, not slipping etc... because what i can see from what im reading you have an electrical problem with the transmission wiring.. check the plugs that plug in the transmission, and follow them, im sure you will find something skint up somewhere.
