5 INSPECT ENGINE COOLANT TEMPERATURE SENSOR(RESISTANCE)
(a) Remove the engine coolant temperature sensor.
(b) Measure the resistance between the terminals of the en-
gine coolant temperature sensor.
Standard:
Tester ConnectionSpecified Condition
1 – 22.32 to 2.59 kΩ at 20C (68F)
1 – 20.310 to 0.326 kΩ at 80C (176F)
NOTICE:
When checking the engine coolant temperature sensor in
water, be careful not to allow water to get in contact with the
terminals. After checking, dry the sensor.
HINT:
Alternative procedure: Connect an ohmmeter to the installed
engine coolant temperature sensor and read the resistance.
Use an infrared thermometer to measure the engine tempera-
ture in the immediate vicinity of the sensor. Compare these val-
ues against the resistance/temperature graph. Change the en-
gine temperature (warm up or allow to cool down) and repeat
the test.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the intelligent tester II. Freeze frame data record the engine condition when
malfunctions are detected. 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.
1 INSPECT HEATED OXYGEN SENSOR(HEATER RESISTANCE)
(a) Disconnect the H17 heated oxygen sensor connector.
(b) Measure the resistance between the terminals of the
heated oxygen sensor connector.
Standard:
Tester ConnectionSpecified Condition
With HID: 1 (HT) – 2 (+B)11 to 16 Ω at 20C (68F)
With HID: 1 (HT) – 4 (E1)No Continuity
Without HID: 2 (HT) – 1 (+B)11 to 16 Ω at 20C (68F)
Without HID: 2 (HT) – 3 (E1)No Continuity
(c) Reconnect the heated oxygen sensor connector.
NG REPLACE HEATED OXYGEN SENSOR

2 INSPECT EFI RELAY
(a) Remove the EFI relay from the engine room R/B No. 4.
(b) Check the EFI relay resistance.
Standard:
Tester ConnectionSpecified Condition
