The Additional Technical Information：

A critical component of today’s modern vehicle is the sensor measuring the exhaust gases. This sensor works with the vehicle Electronic Control Unit (ECU) to constantly maintain the operation efficiency of the engine. If the oxygen content in the exhaust gas is too high (a lean mixture) or too low (a rich mixture), the sensor is able to transmit this information back to the ECU, which then adjust the air to fuel ratio. 
Not all vehicles have sensors with the same output characteristics and these sensors are not interchangeable. It is important to confirm sensor type before making the repair. 
In vehicles equipped with a heated oxygen sensor, the output voltage changes in accordance with the oxygen concentration in the exhaust gas. The ECU uses this output voltage to determine whether the present air/fuel ratio is richer or leaner than the stoichiometric air/fuel ratio (14.7:1).

Causes of a Rich Condition
  • Plugged air filter
  • Faulty ECU
  • Faulty air mass meter
  • Faulty air flow meter
  • Faulty MAP sensor
  • Faulty idle control valve
  • Faulty fuel pressure regulator
  • Faulty fuel injector(s)
  • Restricted fuel return line
  • Fouled spark plug(s)
  • Faulty ignition wire(s)
  • Ignition timing
  • Faulty oxygen sensor
  • Faulty air fuel sensor
  • Faulty PCV
  • Faulty EVAP
  • Associated wiring 
  • Engine coolant temperature
Causes of a Lean Condition
  • Vacuum leak
  • Faulty ECU
  • Faulty air mass meter
  • Faulty air flow meter
  • Faulty MAP sensor
  • Faulty idle control valve
  • Faulty fuel pressure regulator
  • Faulty fuel pump
  • Restricted fuel filter (screen)
  • Faulty fuel injector(s)
  • Faulty PCV
  • Associated wiring
  • Exhaust gas leak
  • Faulty oxygen sensor
  • Faulty air fuel sensor
