Emission control systems, help control fuel fumes, while cleaning engine producing exhaust gases. Consequently, emission control systems, have been efficient in reducing air pollution, caused by automotive engines. So, emission control systems, depend on a […]

(O2) Oxygen Sensor – Function – Failure Symptoms – With Testing

04/28/2023

The, (O2) Oxygen Sensor, measures the difference, between the amount of oxygen in the exhaust gas. And, the amount of oxygen in air. So, with that information and other sources, the (ECU) can decide, whether […]

Positive Crankcase Ventilation (PCV) System – What Does It Do

12/22/2022

First of all, (PCV) System is the short form or common name, for the Positive Crankcase Ventilation (PCV) System. So, the Positive Crankcase Ventilation (PCV) system, is basically a one way passage. And, is used […]

(O2) Oxygen Sensors – Function, Failure Symptoms, How To Test

10/22/2022

Every vehicle built since the early 1980’s, has one or more (O2) oxygen sensors, integrated into the exhaust system. So, (O2) oxygen sensors, are used to confirm, that the proper air fuel ratio, is actually […]

(EGR) Valve – Common Problems And Troubleshooting Procedures

10/20/2022

The (EGR) valve system, is designed to help minimize, harmful oxides of nitrogen, in the air we breathe. To help do this, the (EGR) valve allows, a calibrated amount of exhaust gas, to re-enter the […]

Evaporative Emission Control System (EVAP) – Function – Failure

08/16/2022

The function of the evaporative emission control system (EVAP), is to trap and store evaporative fuel emissions. The (EVAP) system therefore, totally eliminates fuel vapors, as a source of air pollution. But, sealing the fuel […]
