Secondary air injection (SE only)

Roughly five seconds after the engine has started, the control module grounds pin 26 and causes the secondary air injection pump relay to operate and supply the pump and solenoid valve with current.
The length of time during which the control module grounds pin 26 (air injection pump and valve activated) is dependent on time and temperature, so that the maximum connection time is 80 seconds or until engine temperature rises to 65°C (150°F), whichever occurs first.
No connection of the secondary air injection system occurs at engine temperatures below 1°C (33°F) or above 35°C (95°F).
