DTC 93: Throttle Position Sensor/Steering Angle Sensor NOTE: When both the VSA indicator and the MIL are ON, troubleshoot the PGM-FI system first. Check for an open in the THL1 circuit: 1. Turn the ignition switch ON (II). 2. Measure the voltage between the VSA converter unit 26P connector terminal No. 7 and body ground when the throt- tle valve is fully closed and fully open. Is the voltage as specified? — Fully closed: about 0.5 V — Fully open: about 4.5 V Check the steering angle sensor 4P connector connection. Is the connector disconnected? Check for an open in the steering angle sensor circuits: 1. Turn the ignition switch OFF. 2. Disconnect the VSA control unit 42P connector and the steering angle sensor 4P con- nector. 3. Check for continuity between the VSA control unit 42P con- nector terminal No. 39 and the steering angle sensor 4P connector terminal No. 4. 4. Check for continuity between the VSA control unit 42P con- nector terminal No. 21 and the steering angle sensor 4P connector terminal No. 1. 5. Check for continuity between the VSA control unit 42P con- nector terminal No. 24 and the steering angle sensor 4P connector terminal No. 2. 6. Check for continuity between the VSA control unit 42P con- nector terminal No. 40 and the steering angle sensor 4P connector terminal No. 3. Is there continuity? The system is OK at this time. If the problem recurs, replace the VSA converter unit. VSA CONVERTER UNIT 26P CONNECTOR Repair open in the wire between the PCM and the VSA converter unit.
