Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Jet Mixture System
Jet mixture system supplies fuel to the engine through jet mixture passages and jet valves for optimum air/fuel mixture. The system is calibrated by jet mixture solenoid which responds to electrical impulses from the ECU.
If oxygen sensor detects a lean condition, the ECU energizes the solenoid to enrich the mixture. If sensor detects a rich condition, the ECU signals the solenoid to lean out the mixture.
