DESCRIPTION
On page 4B 43-44 of the 1987 RX-7 Workshop Manual and 4B 78-79 of the 1987 Workshop Manual Supplement, procedures are shown for testing the Switching Solenoid Valve and the Relief Solenoid Valve.
These procedures show using a checker lamp no. 49F0 18 001 which is not sold in the North American market. However, these tests can be performed by using the Throttle Sensor Checker (0000 41 0200) and Attachment "A" (0000 41 0201) as shown below and on the following pages.
SECONDARY AIR INJECTION CONTROL SYSTEM 4B
SWITCHING SOLENOID VALVE Inspection Signal
1. Warm up the engine and run it at idle.
2. Connect a tachometer to the engine.
3. Connect the throttle sensor chocker (0000 41 0200) with attachment A (0000 41 0201) to the check connector (Green).
4. Disconnect the vacuum hose (switching solenoid valve to air control valve) at the air control valve.
5. Place a finger over the hose opening.
6. Check for illumination of the (red lamp) and suction at the hose.
Switching solenoid valve
1. Disconnect the vacuum hoses from the switching solenoid valve.
2. Blow through the solenoid valve from port (A). Check that air passes through the solenoid valve and flows from port (B).
3. Disconnect the solenoid valve connector and connect 12V and ground to the terminals on the solenoid valve.
4. Blow through the solenoid valve from port (A). Check that air passes through the solenoid valve and flows from the air filter.
RELIEF SOLENOID VALVE Inspection Signal
1. Warm up the engine and run it at idle.
2. Connect a tachometer to the engine.
3. Connect the throttle sensor checker (0000 41 0200) with attachment A (0000 41 0201) to the check connector (Green).
4. Disconnect the vacuum hose (relief solenoid valve to air control valve) at the air control valve.
5. Place a finger over the hose opening.
6. Check for illumination of the (green lamp) and that air flows from the hose.
