W/ Single Point Fuel Injection
The
oxygen sensor, located in the exhaust manifold, produces voltage when exposed to oxygen present in exhaust gasses. The sensor produces a low voltage when the air/fuel mixture is lean and a high voltage when the mixture is rich. The voltage signal is transmitted to the logic module which signals the power module to trigger the fuel injector. The injector adjusts the mixture accordingly.
