DTC P007C CAC Outlet Temperature Sensor Circuit Low (4JJ3 with DPD)

1. DTC P007C description

Charge air cooler temperature sensor 2 is installed on the outlet side of the intercooler. Charge air cooler temperature sensor 2 is a variable resistor and measures the intake air temperature at the intercooler outlet. This sensor has a signal circuit and a low reference circuit. The ECM supplies 5 V to the signal circuit, and connects the ground to the low reference circuit. The sensor resistance is high when the intake air temperature is low, and the sensor resistance decreases as the intake air temperature increases. The ECM detects a high voltage when the sensor resistance is high, and a low voltage when the sensor resistance is low. If the ECM detects an excessively low signal voltage, the DTC is set.

2. Condition for setting DTC P007C

Condition for running the DTC

The battery voltage is 10 to 16 V.

The ignition switch is ON.
DTCs P060B and P06D6 are not set.

Refer to "51.Engine Control 1A.Troubleshooting(4JJ3 with DPD) DTC P060B Internal Control Module A/D Processing Performance".

Refer to "51.Engine Control 1A.Troubleshooting(4JJ3 with DPD) DTC P06D6 Sensor Reference Voltage 6 Circuit".

Condition for setting the DTC

The ECM detects that the charge air cooler temperature sensor 2 signal voltage is 0.04 V or less for 4 seconds.

3. Action taken when DTC P007C sets

The ECM illuminates the MIL. Refer to Action taken when DTC sets - Type A.

Refer to "51.Engine Control 1A.Troubleshooting(4JJ3 with DPD) DTC type definitions".

The ECM inhibits the EGR control.
The ECM assumes a default charge air cooler temperature sensor 2 value.

4. Condition for clearing DTC P007C

Refer to Conditions for clearing the MIL/DTC - Type A or Type B.

Refer to "51.Engine Control 1A.Troubleshooting(4JJ3 with DPD) DTC type definitions".
