What is OBD2 ?
OBD stands for On-Board Diagnostics. OBD-II (OBD two) is the latest industry standard, which was introduced on 1996 vehicle models. It provides monitoring of nearly all engine controls, and also some other parts of the vehicle (chassis, body, etc.).
The most useful part of OBD to most drivers is the ability to read information from the vehicle. You can read trouble codes, and even monitor real-time statistics such as RPM, vehicle speed, etc. There are a variety of different devices on the market ranging from basic code scanners to advanced displays that calculate MPG as you drive.
Where is the OBD2 port ?
Free to look the picture below,so it’s depend on what car model you use.
Please check this picture,the OBD2 port position depends on what car model you used.
A.Dongfeng Citroen and a few models.
B.Other few vehicels.
C.Dongfeng Citroen,Dongfeng Peugeot and so on.
D.Honda,Volkswagen Touran,Lexus and so on.
E.GM,Volkswagen,Ford,Toyota,Hyundai,BMW and so on.
What do Engine and Transmission work for?
The transmission works with the engine to provide power to your wheels. It plays a major role in the overall performance of your car whether automatic or manual. In order to check problems immediately, a transmission/transaxle keeps the engine’s output optimally matched to the speed and load, that’s really good for driving safety.
What is the difference between cheap code reader and high price scanner tool?
One customer said:”This one gives you the code and all you have to do is look it up on google. The high value scanner tool will basically google it for you.”
He said maybe right,but not that all.what price scanner depends on what data you want to check.

What can we do for auto error codes P0171,P0101,P0420,P0300…?
p0171
You can try to do these below :
1.The MAF (Mass Air Flow) Sensor is dirty or faulty Note: The use of “oiled” air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.

2.There could be a vacuum leak downstream of the MAF sensor
3.Possible cracked vacuum or PCV line/connection
4.Faulty or stuck open PCV valve
5.Failed or faulty oxygen sensor (bank 1, sensor 1)
6.Sticking/plugged or failed fuel injector
7.Low fuel pressure (possible plugged/dirty fuel filter!)
8.Exhaust leak between engine and first oxygen sensor.
p0101
Large vacuum leaks, split Intake Air Boot or PCV Hose, defective intake manifold gaskets
Mass Airflow Sensor (MAF)
Mass Air Flow Sensor circuit and or wiring problems
Defective Barometric Pressure Sensor
Dirty or contaminated Mass Air Flow Sensing wire or filament
PCM software needs to be updated

Advice
If you just a private car owner,you can check cheap code reader for your car.Normal,that function is enough to diagnostic car,like check engine light.
If you want to check more data or you are auto shop technician,you can choose high price scanner to do more jobs.
