DTC: P0AEE (TC22) Abnormality in characteristics of inverter temperature sensor
INFORMATION
1.
Technical description
•
–
<Description of malfunction>
•
Detected an abnormality in the characteristics of main circuit element temperature detecting sensor (Low abnor-
mality).
2.
DTC set condition
(1)
DTC detection condition
•
Control power supply voltage is 8 V or more.
•
Inverter start signal is ON.
•
Since the engine speed reaches 600 r/min or more, 180 seconds or more have passed.
•
The engine intake air temperature is -10
C {14
F} or more.
•
No abnormality is detected in the engine intake air temperature sensor.
•
A state in which the square sum of motor current for 20 seconds
≥
350,000 [A
2
s] is detected 3 times (engine
intake air temperature
≤
20 °C {68
F}).
•
A state in which the square sum of motor current for 20 seconds
≥
100,000 [A
2
s] is detected 3 times (engine
intake air temperature > 20 °C {68
F}).
(2)
Judgement criteria
•
A state in which the deviation (Max - Min) of main circuit element temperature
≤
2.0 °C {35.6
F} is met 3 times
in 120 seconds.
3.
Reset condition
•
When the abnormality is not confirmed, a state in which the deviation (Max - Min) of variable (main circuit element
temperature) > 2.0 °C {35.6
F} is met 3 times in 120 seconds.
4.
Indication, warning or system control regulation when the DTC is set.
•
MIL: ON
•
HV warning light: ON
5.
Symptoms on the vehicle when the DTC is set
<Symptoms on the vehicle due to backup control (fail safe)>
•
–
<Symptoms on the vehicle due to malfunction>
•
The engine may become unable to start. (Note, however, that vehicles equipped with a starter will be started with
the starter.)
•
Idling stop is not available.
•
The regeneration function stops, reducing the feeling of deceleration during deceleration.
6.
Pre-inspection work
•
Check the battery voltage to make sure that there is no abnormality.
7.
After-inspection work
•
Clear the recorded DTC.
•
Check that no DTC is detected after test-driving the vehicle.
8.
Estimated failure factors
•
Malfunction of inverter
