Detailed Description of Error P0067

OBDII error code P0067 stands for ''Air Assisted Injector Control Circuit High''. This code is set when the Engine Control Module (ECM) detects a problem with the air assisted injector control circuit. The air assisted injector is used to help improve engine performance and reduce emissions by injecting a mixture of air and fuel into the combustion chamber.

The air assisted injector control circuit is a critical component of the engine management system, and when it malfunctions, it can cause problems with engine performance, fuel efficiency, and emissions. The ECM monitors the voltage in the air assisted injector control circuit and sets the P0067 code when it detects a voltage that is higher than expected.

Possible Causes of Error P0067

  • Short circuit in the air assisted injector control circuit
  • Open circuit in the air assisted injector control circuit
  • Faulty air assisted injector
  • Bad ECM (rare)
  • Wiring harness damage or corrosion
  • Loose or corroded connections in the air assisted injector control circuit
  • High resistance in the air assisted injector control circuit

Possible Fixes for Error P0067

  • Check the wiring harness and connections for damage or corrosion and repair as needed
  • Use a multimeter to test the voltage in the air assisted injector control circuit and check for short circuits or open circuits
  • Replace the air assisted injector if it is faulty
  • Use a scan tool to clear the code and test the circuit again
  • If the problem persists, consult a professional mechanic for further diagnosis and repair
