Mac Pro (Mid 2010 and later): Apple Hardware Test diagnostic alerts

Symptoms

If you test a Mac Pro (Mid 2010 and later) with Apple Hardware Test (AHT), you might encounter an alert indicating that the computer does not pass the reading of the following sensor:

4SNS/1/40000001:Ip6M-0.972

Note: "0.972" is a value and may vary.

Resolution

Although the diagnostic displays the alert that the hardware does not pass for this specific sensor, the computer can be considered as passing. The diagnostic tool does not interpret the sensor value correctly. If other messages are also reported, contact AppleCare or your nearest Apple Service Provider.
