Coolant Temperature Sensor Abnormality (Dtc P0117 / 110-4, P0118 / 110-3) - Kubota 07-CR-E5 Manual

07-CR-E5,07-CR-TE5,07-CR-TIE5, DM
(11) Coolant Temperature Sensor Abnormality (DTC P0117 / 110-4, P0118 /
110-3)
P0117 / 110-4: Coolant temperature sensor: Low
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
Limp home action by engine ECU (system action):
• During start-up = −25 °C (−13 °F) [default value]
• Under other conditions = 80 °C (176 °F) [default value]
• Output limitation: Approximately 75 % of normal condition
• EGR stop
• Intake throttle 100 % open
Recovery from error:
• Key switch turn OFF
P0118 / 110-3: Coolant temperature sensor: High
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
Limp home action by engine ECU (system action):
• During start-up = −25 °C (−13 °F) [default value]
• Under other conditions = 80 °C (176 °F) [default value]
• Output limitation: Approximately 75 % of normal condition
• EGR stop
• Intake throttle 100 % open
Recovery from error:
• Key switch turn OFF
