Diagnostic Procedure 13 - Accelerator Pump Control Solenoid Valve
1
INSPECTION START
2
CHECK OVERALL FUNCTION. 1) Make sure that engine is cold. [Engine temperature is below 75 deg C (167 deg F) (2WD M/T models for Germany), 60 deg C (140 deg F) (Except 2WD M/T models for Germany).] 2) Turn ignition switch ON. 3) Listen to accelerator pump control solenoid valve operating sound. Clicking noise should be heard.

N.G.
3
CHECK POWER SUPPLY. 1) Turn ignition switch OFF. 2) Disconnect carburetor harness connector F7. 3) Turn ignition switch ON. 4) Check voltage between terminal d and ground. Voltage: Battery voltage
N.G.
Check the following. - Harness connectors F33, M37 - 10A fuse - Harness continuity between carburetor and fuse. If N.G., repair harness or connectors.
O.K.
4
CHECK OUTPUT SIGNAL CIRCUIT. 1) Turn ignition switch OFF. 2) Disconnect E.C.U. harness connector. 3) Check harness continuity between E.C.U. terminal 108 and terminal b. Continuity should exist.
N.G.
Repair harness or connectors.
O.K.
5
CHECK COMPONENT (Accelerator pump control solenoid valve). Refer to Electrical Components Inspection. (See page EF & EC-146.)
N.G.
Replace accelerator pump control solenoid valve.
O.K.
