Frequently Asked Questions
Q: What does the IQA code on the Bosch 0445120231 injector mean?
A: The IQA (Injector Quantity Adjustment) code printed on the top of the injector is a calibration code specific to that individual injector's flow characteristics. Critical: After installing a new 0445120231 injector, you must input this code into the Komatsu engine ECU using diagnostic software. Failure to do so will result in rough running, low power, and active fault codes.
Q: How can I tell if my Bosch 0445120231 injector is failing on a Komatsu PC200-8?
A: Common signs include excessive black smoke under acceleration, noticeable loss of digging power, increased fuel consumption, and a distinct "knocking" sound from the affected cylinder. You may also see fault codes related to fuel rail pressure deviation or injector circuit faults.
Q: Is this a genuine Bosch injector?
A: COGENG Genuine injectors are built with genuine Bosch cores and components, assembled to strict OEM specifications. This ensures the same durability, flow accuracy, and spray pattern as the original factory-installed part, providing a cost-effective alternative to dealership pricing.
