Cylinder Head Temperature Sensor

1. Connect ohmmeter between terminal 14 or EFI harness connector and ground
2. With cylinder head temperature above 68 degrees F, resistance should be less than 2900 ohms.
3. With cylinder head temperature below 68 degrees F, resistance should be above 2100 ohms.
4. If readings are not within specifications, check wiring harness between cylinder head temperature sensor and control unit. If wiring is satisfactory, check sensor as outlined in "Component Testing".
