FI-36 EFI SYSTEM — Troubleshooting with Volt/Ohmmeter (7M-GE) No. | Terminals | Trouble | Condition | STD voltage 1 | IDL — E2 | No voltage | Throttle valve open | 10 ~ 14 V 2 | VC — E2 | No voltage | Ignition switch ON | 4 ~ 6 V | VTA — E2 | | Throttle valve fully closed | 0.1 ~ 1.0 V | | | Throttle valve fully open | 4 ~ 6 V Throttle Position Sensor [Diagram showing connections between Throttle Position Sensor and ECU with terminals E2, IDL, VTA, VC and ECU terminals +B (+B1), E2, IDL, VTA, VC, E1] IDL — E2 1. There is no voltage between ECU terminals IDL and E2. (IG SW ON) (Throttle valve open) 2. Check that there is voltage between ECU terminal +B (+B1) and body ground. (IG SW ON) NO | OK Check wiring between ECU terminal E1 and body ground. OK | BAD Try another ECU. | Repair or replace. BAD Refer to No. 1. (See page FI-35) | Repair or replace. OK 3. Check throttle position sensor. BAD | OK Repair or replace | Check wiring between ECU and throttle position sensor. OK Try another ECU.
