P0098: Intake Air Temperature Sensor Out Of Range (High) - Hino Motors HINO 155 series Workshop Manual

P0098: Intake air temperature sensor (intake manifold) - out of range (Out of range high)
INFORMATION
Common rail
pressure sensor
Intake manifold
temperature sensor
1. Technical description
• The intake air temperature sensor (intake manifold) installed to the intake manifold consistently measures intake
manifold temperature.
<Description of malfunction>
• The intake manifold temperature cannot be correctly recognized.
2. DTC set condition
(1) DTC detection condition
• Starter key "ON".
• Battery voltage is in the range of 10 V to 16 V.
• The engine is stopped, or the engine speed remains at 500 r/min or more for 5 seconds or more.
(2) Judgement criteria
• Intake manifold temperature sensor output remains less than 4.87 V (-35 C {-31 F}) for 3 seconds or longer.
3. Reset condition
• After restoration to normal condition
4. Indication, warning or system control regulation when the DTC is set.
• MIL: ON
• SVS light: OFF
5. Symptoms on the vehicle when the DTC is set
<Symptoms on the vehicle due to backup control (fail safe function)>
• –
<Symptoms on the vehicle due to malfunction>
• –
6. Pre-inspection work
• Check that the battery voltage is in the normal range.
