• Voltage below 0.224 V for more than 1 s.

Dependents: 

• None.

System reaction to a fault: 

• A substitute value is calculated continuously as follows: Starting intake air temperature is incremented with 1°C per 60 g air mass/s. The value is maximized to 90°C and is used as soon as fault criteria for the sensor are fulfilled.

OK report: 

• P0116  Test 1 and Test 2 performed once and fault criteria not fulfilled. Fault criteria for P0117  or P0118  not fulfilled.
