EFI SYSTEM — Troubleshooting for EFI Electronic Circuit with Volt/Ohmmeter FI-41 No. | Terminals | Trouble | Condition | STD Voltage 6 | No. 10 — E₁ No. 20 — E₁ | No voltage | Ignition switch ON | 9 — 14V Fusible Link Fusible Link — Fuse — Igniter Ignition S/W Fusible Link Battery Solenoid Resistor — ECU Injector No. 10 No. 20 IG S/W E₁ E₁₊₂ FI0798 Voltmeter No. 10 — ECU V ⁺ ⁻ No. 20 FI0799 ① There is no voltage between ECU terminal No. 10 and/or No. 20 and E₀₁ or E₀₂. (IG S/W ON) ② Check that there is specified voltage between resistor terminal (+) and body ground. STD voltage: 10 — 13V OK | NO Check fuse, fusible link and ignition switch. | BAD | Repair or replace OK Check main relay No. 2. | BAD | Replace OK Check circuit between resistor and battery. | BAD | Repair or replace ② Check that there is specified voltage between resistor terminal (—) and body ground. STD voltage: 10 — 13V OK | BAD ③ Check resistance of magnetic coil in the each injector. STD resistance: 1.5 — 3.0Ω | Replace resistor. OK | BAD Check wiring between ECU and injector. | Replace injector. OK | BAD Try another ECU. | Repair or replace Solenoid Resistor (—) (+) Voltmeter FI0800 Ohmmeter Ω FI0801
