Test R - Throttle Kicker
- Check air and vacuum lines to throttle kicker solenoid for blockage, kinks, leaks and proper routing. Repair as required and repeat Quick Test. If all okay, service codes 12 and 13 (if present) and go to next step.
- Disconnect vacuum lines at throttle kicker solenoid and install vacuum pump and vacuum gauge. Apply 20 in. Hg. If vacuum holds, go to next step. If vacuum does not hold, replace throttle kicker solenoid and repeat Quick Test.
- With 20 in. Hg applied at throttle kicker solenoid, perform Engine Running Self-Test. If code 12 or 13 present, EEC system okay, adjust idle speed. If no code 12 or 13, go to next step. Remove vacuum pump and gauge and reconnect hoses at throttle kicker solenoid.
- Turn ignition off and wait 10 seconds. Enter Output State Check and perform Key On-Engine Off Self-Test until end of Continuous code display. DVOM will indicate zero volts. Depress and release throttle and observe DVOM. If DVOM registered high voltage, remain in Output State Check and go to next step. If DVOM did not register high voltage, depress throttle to wide open position and release. If voltage still does not register high reading, go to TEST O - NO CODES, IMPROPER CODES , step 13).
- Remain in Output State Check. Disconnect vacuum lines at throttle kicker solenoid and install vacuum pump to supply port and vacuum gauge to output port. Apply 6 in. Hg. vacuum to solenoid. While cycling output on and off (depressing and releasing throttle) observe vacuum gauge. If vacuum output cycles on and off, go to next step. If vacuum does not cycle on and off, remove test equipment, replace throttle kicker solenoid and repeat Quick Test.
- Disconnect vacuum lines at throttle kicker solenoid and start engine. If vacuum is present, EEC system okay, check idle adjustment. If no vacuum present, repair source of vacuum blockage or leak and repeat Quick Test.
