If you are investigating live data shown in unfamiliar units, save every stored and pending code before clearing anything. Some tools label manufacturer-specific data differently; verify definitions before interpreting. Record the engine temperature and load alongside the reading; the same value can mean different things in different conditions.
A basic reader may not access every module. Compare values only with specifications for the exact vehicle and operating condition. Use the exact vehicle’s service information to interpret the result.
Quick educational note
For information, not a diagnosis or repair instruction. Vehicle-specific checks are still required. Consult the manufacturer's guidance and a qualified technician.
