When \u201cODT Open\u201d malfunction is active 47 will be substituted by default. The sensor is monitored continuously and if resistance is above 310kohm for 1 second this malfunction will occur. Once sensor value drops below 310kohm for 1 second the malfunction will clear. Since achieving discharge superheat is an integral requirement for startup, when this sensor does not read a valid value, the system will only run at startup speed. Normal operation will resume once valid ODT value is read by PCM.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Measure resistance value of thermistor at the PCM connector. If value is above 310kohm, and OAT and OCT measure above 25F, look for a break in the wiring or at the connector itself. If no breaks are observed, replace sensor. If measured resistance is within allowable range, replace PCM.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<p class=\"has-small-font-size
