Codes de défaut couverts
52-04
The liquid line thermistor is only used for charging and subcooling calculation and not required for any other critical system operation. A faulted LLT will make subcooling calculation unavailable in charge mode.
If the resistance value of LLT thermistor is lower than the electrical circuit is capable of measuring, this fault will be generated. Measure resistance value of thermistor at the PCM connector. If value is above 1kohm, look for bare wire, short in the wiring, or at the connector itself. If no bare wires or shorts are observed, replace sensor. If measured resistance is within allowable range, replacing the PCM-VFD is necessary to eliminate this code.
