Go to Step 2. Replace the
Temp/Hum
Sensor
(
page 8-110).
2 Check the Humidity signal.
Disconnect P/J231.
Is the voltage across P/J231-2 <=>
P/J231-3 less than +3 V and above
+0.5 V.
Go to Step 4. Go to Step 3.
3 Check the Temperature signal.
Disconnect P/J231.
Is the voltage across P/J231-4 <=>
P/J231-3 greater than +2.5 V?
Go to Step 4. Replace the
Engine Control
Board
(
page 8-106).
4 Check for +5 V to the Temperature/
Humidity Sensor.
