Throttle Control Module (TCM)
On harness side measure voltage between terminals No. 10 or 20, and terminals No. 2, 3, 4, 5, 7, 14 and 15. See Figure-Figure and Figure-Figure . See TCM INSPECTION TABLE.
TCM INSPECTION
| TerminalNo. | Item | Condition | Data |
| 2 | Throttle Opening Signal | Ignition On | Approximately 0.3-3.3 Volts Voltage Varies W/ Throttle Opening Angle |
| 3 | Secondary Throttle Sensor | Vehicle Running | Approximately 0.4-4.4 VoltsVoltage Varies W/ Secondary Throttle Valve Opening Angle |
| 4 | Secondary Throttle Signal | Vehicle Running | Approximately 0.3-3.3 Volts Voltage Is 3/4 Of Voltage At Secondary Throttle Sensor |
| 5 | Engine Temp. Sensor For TCM | Engine Running | Approximately 0-5 Volts Voltage Varies With Engine Temperature |
| 7 | TCS Switch | Ignition On | Approximately 10 Volts |
| 14 | Throttle Motor Relay | Ignition On | Approximately 1.5 Volts |
| 15 | Power Supply For Sensor | Ignition On | Approximately 5 Volts |
