P1622 INJ ADJ VAL UNRGST
There are several potential reasons for this error code:
01. Faulty Fuel Injector: The fuel injector itself may be faulty or not functioning correctly, preventing communication with the ECM.
02. Wiring or Connector Issue: There could be a problem with the wiring harness or connector that connects the fuel injector to the ECM, causing a communication breakdown.
03. ECM Issue: In some cases, the ECM itself may have a fault, leading to its inability to register or communicate with the injector.
04. Software Issue: Sometimes, the error code may be triggered due to a software glitch or issue in the vehicle's electronic control system.
To diagnose and resolve the problem, it is best to take the vehicle to a qualified mechanic or dealership. They can use specialized diagnostic tools to read the error code, perform further tests, inspect the fuel injectors, check the wiring and connectors, and identify the underlying cause of the issue. Once the root cause is identified, the appropriate repairs can be made to rectify the problem and clear the error code from the ECM.
