The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

SOURCE: obd2 code p0300 on mazda protege 2002

Just had one of these with a maxima, the code is multiple random misfire, when a misfire occurs, to start is do the basics, replace the plugs, check fuel pressure, clean throttle body, and coolant is topped up. also I have seen if the O2 sensor is not working correctly is can cause a misfire, you will need a scan tool to look at what the O2 sensor is doing, o rby back probing the sensor (don't damage the O2 sensor wires). If it wires replace them as well, if it has coils they usually dont give that code if one fails, it will pinpoint that a certain coil if one fals.

SOURCE: code po705 mazda protege lx shaking rough start

The Code you refer to is P0705 Transmission Range Sensor Circuit malfunction (PRNDL Input). It is a possiblility that because this code is present, this sensor is malfunctioning. If it is malfunctioning, that means the engine needs to "guess" the value that this sensor is responsible for. In most cases when this happens, the engine will go for a value that ensures the car runs. The engine will not try to run smooth or efficently, it will only try to run. It is my guess that if you have the sensor checked and replaced, the problem might be fixed. Please let me know if this answers your question and please rate my response. Thank you

IF THE CONECTOR ON THE END IS THE SAME THEN IT WILL WORK AND THE COLORS DO NOT MATTER. YOU HAVE TO MAKE SURE THAT THE CONECTORS ON THE END ARE THE SAME THE AFTERMARKET SUPPLIER DOES NOT USE THE SAME COLORS AS THE FACTORY. A LOT OF TIMES THAT IS HOW WE KNOW WHEN AN AFTERMARKET PART IS USE.
