| DTC Code | DTC Name |
|---|---|
| P06AB11 | Control Module Internal Temperature Sensor "B" Circuit Short to Ground |
| P06AB15 | Control Module Internal Temperature Sensor "B" Circuit Short to Battery or Open |
DESCRIPTION
The ECM has a built-in internal temperature sensor which detects the internal temperature of the ECM. The resistance of the thermistor within the ECM internal temperature sensor changes according to the internal temperature of the ECM. The resistance of the thermistor increases as the ECM internal temperature decreases and decreases as the ECM internal temperature increases.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
|---|---|---|---|---|---|---|
| P06AB11 | Control Module Internal Temperature Sensor "B" Circuit Short to Ground | The ECM internal temperature sensor output voltage is less than 0.22 V for 3 seconds or more (1 trip detection logic). | ECM | Comes on | DTC stored | SAE Code: P06AD |
| P06AB15 | Control Module Internal Temperature Sensor "B" Circuit Short to Battery or Open | The ECM internal temperature sensor output voltage is higher than 4.91 V for 3 seconds or more (1 trip detection logic). | ECM | Comes on | DTC stored | SAE Code: P06AE |
MONITOR DESCRIPTION
The ECM calculates the internal temperature of the ECM based on the output voltage of the ECM internal temperature sensor. If the output voltage of the ECM internal temperature sensor is not within the normal operating range, the ECM will illuminate the MIL and store a DTC. In this case, the ECM internal temperature sensor may be malfunctioning or there may be an open or short in the sensor circuit.
Example:
When the output voltage of the ECM internal temperature sensor is less than 0.22 V, or more than 4.91 V for 3 seconds or more, the ECM illuminates the MIL and stores a DTC.

CONFIRMATION DRIVING PATTERN
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the engine switch off and wait for at least 30 seconds.
Turn the engine switch on (IG).
Turn the GTS on.
Wait 5 seconds.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read the pending DTCs.
Tech Tips
If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P06AB11 or P06AB15.
Check the DTC judgment result.
| GTS Display | Description |
|---|---|
| NORMAL |
|
| ABNORMAL |
|
| INCOMPLETE |
|
Tech Tips
If the judgment result is NORMAL, the system is normal.
If the judgment result is ABNORMAL, the system has a malfunction.
CAUTION / NOTICE / HINT
Tech Tips
Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
CLEAR DTC
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Clear the DTCs.
Turn the engine switch off and wait for at least 30 seconds.
