1. undefined: Check connector between Main PCB and RT sensor for looseness or disconnection. 2. undefined: Reconnect or repair if loose. 3. undefined: Measure sensor resistance. If 0 ohm (short) or open (infinite), replace the sensor. 4. undefined: Compare measured resistance to sensor temperature table. If abnormal, replace sensor. 5. undefined: If resistance is within spec, inspect harness. If harness is intact, replace the main PCB.
