Toyota Corolla (E120): The ambient temperature does not display
Wiring diagram
Inspection procedure
1 Inspect outer ambient temperature sensor
- Remove cooler (ambient temp. Sensor) thermistor.
- measure resistance between terminals 1 and 2 of cooler
(ambient temp. Sensor) thermistor connector at each temperature.
Resistance:
at 0 c (0 f) : 9.097 – 9.701 KΩ at 25 c (77 f) : 2.725 – 2.865 KΩ
Hint
: as the temperature increases, the resistance decreases.
Resistance:
2 Check harness and connector
Check and replace combination meter assy

Circuit description
The rotary solenoid type idle air control (iac) valve is located
under the throttle body and intake air bypassing the throttle
valve flows into the iac valve through the passage.
In this way the intake air volume bypassing the throttle valve is
regulated, controls the engine speed.

Inspection
1. Fuel injector assy
Inspect injector resistance.
Using an ohmmeter,measure the resistance between
the terminals.
Resistance: 13.4 – 14.2 Ω at 20 c (68 f)
Inspect injector inspection
Caution:
keep injector clear of sparks during the test.
