P1414 LAND-ROVER Description
The secondary air injection system is used to limit the emission of carbon monoxide (CO) and hydrocarbons (HCs) that are prevalent in the exhaust during cold starting of a spark ignition engine. The concentration of hydrocarbons experienced during cold starting at low temperatures are particularly high until the engine and catalytic converter reach normal operating temperature. The lower the cold start temperature, the greater the prevalence of hydrocarbons emitted from the engine.
The secondary air injection (SAI) system comprises the following components:
– Secondary air injection pump
– SAI vacuum solenoid valve
– SAI control valves (2 off, 1 for each bank of cylinders)
– SAI pump relay
– Vacuum reservoir
– Vacuum harness and pipes
