Check the resistance at the Tray 2, 3, and 4 Ambient Temperature sensor (SN41)
1. Verify that J5 is connected on the Trays 2, 3, and 4 Controller PCA (A23).
2. Disconnect the connector from SN41.
3. Check the resistance at pins 2 to 4 on the wire harness.
„Trays 2, 3, and 4 assembly wiring diagram" auf Seite 2296
HINWEIS: If SN41 is touched, the temperature reading changes quickly.
Is the resistance approximately 12000 ohms (70F/20C) and 9600 ohms (80F/26C) at SN41?
No Yes
Check the following conditions
1. Verify that the Tray 2, 3, and 4 Ambient Temperature sensor (SN41) is clean and has no
obstructions.
2. Check the electrical connections and wiring between SN41 and the Trays 2, 3, and 4 Controller

PCA (A23).
Replace the Tray 2, 3, and 4 Ambient Temperature sensor (SN41)
1. Verify that SN41 is clean and has no obstructions.
2. Check the electrical connections and wiring between SN41 and the Trays 2, 3, and 4 Controller PCA (A23).
3. If SN41 is clean and the connections are secure, then replace the sensor.
