Possible cause

P011C

CAT/IAT CRRLTN B1
(Charge air temperature/Intake 
air temperature correlation)

• ECM detects a state that the temperature 

difference between intake air temperature 
sensor 1 and 2 remains 20

°C (68°F) or less 

continuously for 5 seconds or more.

• ECM detects a state that the difference be-

tween the temperature of intake air temper-
ature sensor 2 and its estimated 
temperature calculated by ECM from in-
take air temperature 1 and turbocharger 
boost sensor remains 106

°C (223°F) or 

more continuously for 5 seconds or more.

• Harness or connectors

(High or low resistance in the intake 
air temperature sensor 1 circuit)
(High or low resistance in the intake 
air temperature sensor 2 circuit)

• Intake air temperature sensor 1
