Why is my OBD2 scan not working properly?
But after conducting research online and speaking to different mechanics and technicians, I found out that a wide range of problems can cause it. These issues include an incompatible obd2 scan tool, bad fuses, damage in the circuit board, ECU, and failed computer.
Is the OBD2 scanner capable of reading the enhance code?
They are however nor capable of reading enhance codes or OEM which are mostly specific to vehicles. Generic codes are also known as P0 codes, while the enhance codes are called the P1 codes. Enhanced codes mostly change depending on the model year and should be regularly replaced or updated.
What kind of plug do I need for OBD2 scanner?
The end of the cable will normally have a 16-pin plug that should give a perfect fit into the cars outlet. Turn on the ignition key or run the car, whichever is in the manual, and give time for the scanner to initialize.
How does the OBD-II system work and FAQ?
How the OBD-II system works and FAQ !! All modern cars and trucks have a computer (in the photo) that controls the operation of the engine, automatic transmission and emission control systems. This computer is usually called the PCM (Powertrain Control Module) or the ECM (Electronic Control Module).

What is the lean code for an OBD 2 engine?
The OBD II system may or may not detect the fault and set a lean code (P0171 and/or P0174) in addition to misfire codes. Unmetered air that gets into the engine behind an airflow sensor can lean out the fuel mixture to the point where it may not ignite when the spark plug fires.
What does O2 sensor voltage mean on OBD2 scanner?
Assuming your O2 sensor voltage is high (over 0.5 V), it indicates that there would be a rich exhaust code set. In contrast, your O2 sensor voltage stays low (lower than 0.5 V), it means that there would be a lean exhaust code set. You turn on only the ignition, not all the way.
