MIXTURE __________________________________________________ (range RICH/LEAN) Indicates the general rich or lean condition of the exhaust as measured by the lambda OS. Exhaust oxygen content is related to oxygen content in the intake air/fuel mixture and thus indicates intake air/fuel ratio. The OS is the primary sensor that indicates whether the engine is running rich or lean. The OS must be hot and the ECM must be in closed loop before the ECM will respond to the sensor signal. MIXTURE CORR(CANP ACTIVE) __________________________________ (range YES/NO) Indicates the current mixture correction with canister purge valve active.
