Coolant Temperature Sensor Abnormality (Dtc P0117 / 110-4, P0118 / 110-3) - Kubota V3800-CR-TE4 Diagnosis Manual

V3800-CR-TE4,V3800-CR-TIE4, DM
(10) Coolant Temperature Sensor Abnormality (DTC P0117 / 110-4, P0118 /
110-3)
P0117 / 110-4: Coolant temperature sensor abnormality (Low side)
Behaviour during malfunction:
• Amount of white smoke increases at low temperatures
• Insufficient output
• Worsening exhaust gas performance
Detection item:
• Ground short circuit of sensor / harness
DTC set preconditions:
• Battery voltage is normal
DTC set parameter:
• Voltage of coolant temperature sensor is 0.1 V or less
Engine warning light:
• ON
System action:
• At start-up = − 25 °C (− 13 °F) [default value]
• Under other conditions = 80 °C (176 °F) [default value]
• Output limitation: Approximately 50 % of normal condition
• Speed limitation (Accelerator limitation: 50 %)
• EGR stop
Recovery from error:
• Key switch turn OFF
P0118 / 110-3: Coolant temperature sensor abnormality (High side)
Behaviour during malfunction:
• Amount of white smoke increases at low temperatures
• Insufficient output
• Worsening exhaust gas performance
Detection item:
• Open circuit or +B short circuit of sensor / harness
DTC set preconditions:
• Battery voltage is normal
DTC set parameter:
• Voltage of coolant temperature sensor is 4.9 V or above
Engine warning light:
• ON
System action:
• At start-up = − 25 °C (− 13 °F) [default value]
• Under other conditions = 80 °C (176 °F) [default value]
• Output limitation: Approximately 50 % of normal condition
• Speed limitation (Accelerator limitation: 50 %)
• EGR stop
Recovery from error:
• Key switch turn OFF
