Toyota Avalon (XX50): Control Module Internal Temperature Sensor "B" Circuit Short to Ground (P06AB11,P06AB15). Engine Oil Pressure Control Circuit Open (P06DA13). Low Pressure Fuel System Pressure - Too Low (P008A00)

Toyota Avalon (XX50) 2019-2022 Service & Repair Manual / Engine / A25a-fxs Engine Control / Sfi System / Control Module Internal Temperature Sensor "B" Circuit Short to Ground (P06AB11,P06AB15). Engine Oil Pressure Control Circuit Open (P06DA13). Low Pressure Fuel System Pressure - Too Low (P008A00)

Control Module Internal Temperature Sensor "B" Circuit Short to Ground (P06AB11,P06AB15)

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.

The ECM internal temperature sensor output voltage is higher than 4.91 V for 3 seconds or more (1 trip detection logic).

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 higher than 4.91 V for 3 seconds or more, the ECM illuminates the MIL and stores a DTC.
