RADIATOR SENSOR CIRCUIT

Radiator Sensor Circuit (Part 1):

Radiator Sensor Circuit (Part 2):

CIRCUIT OPERATION
- The battery voltage is applied from the ignition switch to the radiator sensor (terminal No.3), and it is grounded to the vehicle body from the radiator sensor (terminal No.1).
- The radiator sensor (terminal No.2) sends the sensor signal to the powertrain control module (terminal No.3).

MONITOR EXECUTION
- Continuous

MONITOR EXECUTION CONDITIONS (OTHER MONITOR AND SENSOR)

Other Monitor (There is no temporary DTC stored in memory for the item monitored below)
- Not applicable

Sensor (The sensor below is determined to be normal)
- Not applicable

DTC SET CONDITIONS

Logic Flow Chart:

Check Condition
- Ignition switch: "ON"
- Battery positive voltage is higher than 11 volts
- Engine coolant temp -30 °C (-22 °F) to 110 °C (230 °F)

Judgement Criteria
- When the radiator sensor is defective
- When the PCM is defective

TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THIS CODE TO BE SET ARE:)
- Malfunction of the radiator sensor
- Malfunction of the PCM

DIAGNOSIS
