DTC: P011C

P011C: Intake air temperature sensor (air flow sensor built-in) - rationality
INFORMATION
Coolant temperature sensor
Body earth
Intake air
temperature sensor
(air flow sensor built in)
1. Technical description
• The intake air temperature sensor with built-in air flow sensor constantly measures the intake air temperature.
<Description of malfunction>
• Intake air temperature is not correctly recognized.
2. DTC set condition
(1) DTC detection condition
The following conditions continue for at least 20 seconds:
• Engine speed is 1,000 r/min or less.
• Fuel injection rate is at least 35 mm
• Engine coolant temperature is between -30 C {-22 F} to 55 C {131 F}.
• 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
The following conditions continue for at least 3 seconds:
• Difference between intake air temperature (air flow sensor) and intercooler outlet temperature is at least 30 C
{86 F}, and difference between intake air temperature (air flow sensor) and intake manifold air temperature is
at least 30 C {86 F}.
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
