HYBRID CONTROL SYSTEM, Diagnostic DTC:P0A2B-250, P0A2E-248
| DTC Code | DTC Name |
|---|---|
| P0A2B-250 | Drive Motor "A" Temperature Sensor Circuit Range / Performance |
| P0A2E-248 | Drive Motor "A" Temperature Sensor Circuit Intermittent |
DESCRIPTION
The resistance of the thermistor built into the motor temperature sensor changes in accordance with changes in MG2 temperature. The lower the MG2 temperature, the higher the thermistor resistance. Conversely, the higher the MG2 temperature, the lower the resistance.
Tech Tips
The term "drive motor A" indicates MG2.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
|---|---|---|---|---|---|
| P0A2B-250 | Drive Motor "A" Temperature Sensor Circuit Range / Performance | Motor temperature sensor output does not increase under conditions in which the value should increase, or output does not decrease under conditions in which the value should decrease. | Hybrid vehicle motor assembly (Motor temperature sensor) | Does not come on | Master Warning Light: Comes on |
| P0A2E-248 | Drive Motor "A" Temperature Sensor Circuit Intermittent | Unusual sudden change in motor temperature sensor output occurs and the condition continues, or unusual sudden change in motor temperature sensor output occurs repeatedly. | Hybrid vehicle motor assembly (Motor temperature sensor) | Does not come on | Master Warning Light: Comes on |
PROCEDURE
-
REPLACE HYBRID VEHICLE MOTOR ASSEMBLY
Tech Tips
The motor temperature sensor is not available as a supply part. If it requires replacement, replace the hybrid vehicle motor assembly.
