1. Outside air temperature sensor
DTC detecting condition Possible cause
DTC B1141 (DTC No. 1141):
Input signal from outside air temperature sensor is higher
than 4.88 V.
• Open in outside air temperature sensor circuit
• Outside air temperature sensor malfunction
• BCM malfunction
DTC B1142 (DTC No. 1142):
Input signal from outside air temperature sensor is lower
than 0.1 V.
• Short in outside air temperature sensor circuit
• Outside air temperature sensor malfunction
• BCM malfunction
Step Action Yes No
1 Outside air temperature sensor check
1) Turn ignition switch to OFF position.
2) Disconnect connector from outside air temperature
sensor.
3) Check outside air temperature sensor for resistance
referring to “Outside Air Temperature Sensor Inspection
(If Equipped) in Section 9C”.
Is it in good condition?
Go to Step 2. Replace outside air
temperature sensor.
2 Outside air temperature sensor circuit check
1) Disconnect connector from BCM and check for proper
terminal connection to BCM connector.
2) If connections are OK, check outside air temperature
sensor circuit for open, short and high resistance.
Is each circuit in good condition?
Substitute a known-
good BCM (included in
junction block) and
recheck. Repair circuit.
