Toyota Corolla (E120): Circuit description

Monitor description
The ecm commands gearshift by turning the shift solenoid valves ”on/off”. When there is an open or short circuit in any shift solenoid valve circuit, the ecm detects the problem and the mil comes on. Illuminating the mil, the ecm performs the fail–safe and turns the other shift solenoid valves in good condition ”on/off” (in case of an open or short circuit, the ecm stops sending current to the circuit.).

Foamed material application areas
If an increase in temperature or other condition damages the foamed material
when repairing or replacing the panel,
fill in the insufficient areas with urethane foam. The following illustration
shows the areas for one side, but the
foamed material must be applied equally to both the left and r ...
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.
