(3) Injector with QR Codes
• QR (Quick Response) codes have been adopted to enhance correction precision. The QR code, which contains the
correction data of the injector, is written to the engine ECU. QR codes have resulted in a substantial increase in the
number of fuel injection quantity correction points, greatly improving injection quantity precision.
< NOTE >
QR codes are a new two-dimensional code that was developed by DENSO. In addition to injection quantity correction
data, the code contains the part number and the product number, which can be read at extremely high speeds.
