Secondary Air Injection Pump Relay - J299- / Secondary Air Injection Pump Motor - V101-, Checking

General Description

The secondary air injection system sends air into the exhaust using passages in the cylinder head. This extra air injection takes place using the Secondary Air Injection Pump Motor -V101- that is powered by the Secondary Air Injection Pump Relay -J299- on a cold-start of the engine for about 45 - 100 sec. and serves to quickly heat the catalytic converter(s) for improved emissions.
