How can I check the resistance of a Pioneer temperature sensor?Updated 8 hours ago

Introduction

Understand how to the check the resistance of a Pioneer temperature sensor.

Prerequisites

Recommended parts to prepare:

• Multimeter capable of measuring resistance readings.An example of a digital multimeter. Set the meter to read resistance.

Steps

1. Gain access to the system control board by disassembling the Pioneer system. The temperature sensor plugs into the system control board.
2. Confirm the connection between the temperature sensor and Printed Circuit Board (PCB). Note: Some temperature sensor related errors can occur due to improper connections.
3. Unplug the temperature sensor completely.
4. Measure the resistance value of the temperature sensor, as well as the current outdoor temperature. Use the 2 probes of the multimeter that are set to read resistance.
   Use the multimeter's 2 probes and record the resistance reading
5. Record the value.
6. Compare the value against the reference charts below to confirm if the temperature sensor has faulted. Note: The proper resistance value for Pioneer Split equipment (Quantum Series) is next to the current outdoor temperature reading.
