Test 19 - Checking Solenoid Kicker Operation 2.2L Models

Remove air cleaner cover. Look at plunger of solenoid kicker diaphragm while starting engine. The vacuum diaphragm plunger should move out and hold the throttle open for at least 5 minutes. It should then return the throttle to curb idle position.
NOTE: Some systems may hold throttle open for less than 5 minutes.
If the plunger movement is okay, go to step 3). If there's no plunger movement, go to step 4).
Press A/C button and look at plunger for solenoid kicker vacuum diaphragm. Vacuum plunger should move out and hold the throttle open while the A/C compressor clutch is engaged. If plunger movement is okay, go to TEST 20 . If there's no plunger movement, go to step 4).

Connect diagnostic readout box to the engine harness connector. Put system in the "Switch Test Mode". Make sure A/C control is in the "OFF" position. Press the A/C button on and off.
Code 88 should appear on the display when the A/C button is pressed on and then return to 00 when turned off. If code 88 appears when A/C button is turned on, replace the computer. If code 88 does not appear, go to step 6).
Turn ignition switch off. Disconnect computer 14-wire connector. Connect a voltmeter to cavity No. 7 of the 14-wire connector and ground. Make sure A/C button is off. Turn the ignition switch to the "RUN" position.
Voltmeter should read within one volt of battery voltage. If voltage is okay, replace the computer. If voltage is not okay, repair wire of cavity No. 7 for an open circuit to the A/C push button switch.
Turn the engine off. Disconnect the vacuum supply hose from the solenoid kicker and connect a vacuum gauge to it. Start the engine. Vacuum gauge should indicate intake manifold vacuum. If vacuum is okay, replace the computer. If there's no vacuum, repair vacuum supply from the carburetor.
