HYBRID CONTROL SYSTEM, Diagnostic DTC:P0A37-260, P0A3A-258
| DTC Code | DTC Name |
|---|---|
| P0A37-260 | Generator Temperature Sensor Circuit Range / Performance |
| P0A3A-258 | Generator Temperature Sensor Circuit Intermittent |
DESCRIPTION
The resistance of the thermistor built into the generator temperature sensor changes in accordance with changes in MG1 temperature. The lower the MG1 temperature, the higher the thermistor resistance. Conversely, the higher the MG1 temperature, the lower the resistance.

| DTC No. | INF Code | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| P0A37 | 260 | Generator temperature sensor output does not increase in which the value should increase, or output does not decrease under conditions in which the value should decrease. | Hybrid vehicle transaxle assembly (Generator temperature sensor) |
| P0A3A | 258 | Unusual sudden change in generator temperature sensor output occurs and the condition continues, or unusual sudden change in generator temperature sensor output occurs repeatedly. |
PROCEDURE
-
REPLACE HYBRID VEHICLE TRANSAXLE ASSEMBLY
Tech Tips
The generator temperature sensor is not available as a supply part. If it requires replacement, replace the hybrid vehicle transaxle assembly.
