Hi,
As per Manual, this Refers to Open Probe Connection.
Solutions Offered in Manual :-
1. (F30 or F31) Check resistance at room temperature & compare to *RTD Sensor resistance chart. If resistance does not match the RTD chart replace RTD Sensor Probe. Check Sensor wiring harness between EOC & Sensor Probe connector.
2. (F30 or F31) Check resistance at room temperature, if less than 500 ohms, replace *RTD Sensor Probe. Check for shorted Sensor Probe harness between EOC & Probe connector.
The chart is :-
Temperature (�F) Resistance (ohms)
32 � 1.9 - 1000 � 4.0
75 � 2.5 -1091 � 5.3
250 � 4.4 - 1453 � 8.9
350 � 5.4 -1654 � 10.8
450 � 6.9 -1852 � 13.5
550 � 8.2 - 2047 � 15.8
650 � 9.6 -2237 � 18.5
900 � 13.6 - 2697 � 24.4
Let me know, if needed further assistance.
Hope i helped you.
