Engine Oil Temperature Sensor
Engine Oil Temperature Sensor
The engine oil temperature sensor is used to detect the engine oil temperature. The sensor modifies a voltage signal from the ECM.
The modified signal returns to the ECM as the engine oil temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.
<Reference data>
| Engine oil temperature [C (F)] | Voltage* (V) | Resistance (kΩ) |
| -10 (14) | 4.4 | 7.0 11.4 |
| 20 (68) | 3.5 | 2.10 2.90 |
| 50 (122) | 2.2 | 0.68 1.00 |
| 90 (194) | 0.9 | 0.236 0.260 |
| 110 (230) | 0.6 | 0.143 0.153 |
*: These data are reference values and are measured between ECM terminals.
EVAP Canister Purge Volume Control Solenoid Valve
The EVAP canister purge volume control solenoid valve uses a ON/ OFF duty to control the flow rate of fuel vapor from the EVAP canister.
The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.
