Frequently Asked Question

Cause:

1. The instrument is configured for the wrong temperature units (Fahrenheit vs. Celsius).
2. The wrong type sensor is being used with the EIS.
3. The sensor is bad.

Troubleshooting:

1. Checking the EIS temperature units configuration. (See the user manual.) The most likely cause of this problem is simply that the instrument is operating in Celsius instead of Fahrenheit, or vice versa.
2. The incorrect sensor is being used. (See the background section for the oil temperature / coolant temperature section above.)
3. It is very unlikely that the instrument or the sensor has become inaccurate. The accuracy of the sensor can be checked by placing it it boiling water. A ground wire must be connected to its body while performing this test. It should register 212 F (100C) within a few degrees at sea level.
