Toyota Corolla Repair Manual: 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.
- Purchase a new fuel tube, and take out the fuel tube connector from its tube.
Hint
: part no. 23901–0D010
- Connect sst and fuel tube connector to the fuel
pipe.
Sst 09268–41047 (90467–13001, 95336–08070)
Caution
: perform connecting operations of the fuel tube connector (quick type) after observing the precautions.
- Install an o–ring to the fuel injector.
- Connect sst (union and hose) to fuel the injector, and hold the fuel injector to prevent gasoline from splashing out. sst 09268–41047 (90467–13001, 95336–08070, 09268–41110, 09268–41300)
- Put the fuel injector into a graduated cylinder.
Hint
: install a suitable vinyl tube onto the injector to prevent gasoline from splashing out.
- Operate the fuel pump.
- Connect sst to the connector of fuel injector.
Sst 09842–30080
- connect sst to the battery for 15 seconds, and
measure the injection volume with a graduated cylinder.
Test the each fuel injector 2 or 3 time.
Injection volume: 60 – 73 cm3 (3.7 – 4.5 Cu in.) Per 15 seconds difference between each injector: 13 cm3 (0.8 Cu in.) Or less
- Inspect leakage
- in the condition above, disconnect the test probes
of the from the battery, and check the fuel leakage
from the fuel injector.
Fuel drop: 1 drop or less per 12 minutes
2. Fuel pump
- Inspect fuel pump resistance.
- Using an ohmmeter, measure the resistance between
the terminals.
Resistance: 0.2 – 3.0 W at 20 c (68 f)
- inspect fuel pump operation
- apply battery voltage to both terminals. Check that the pump operates.
Notice
:
- these tests must be done quickly (within 10 seconds) to prevent the coil from burning out.
- Keep fuel pump as far away from the battery as possible.
- Always do the switching at the battery side.
On–vehicle inspection
1. Check fuel pump operation
Connect the hand–held tester to the dlc3.
turn the ignition switch on and hand–held tester main
switch on.
Notice:
do not start the engine.

System description
The ecm uses signals from the vehicle speed sensor and crankshaft position
sensor to detect the actual
gear position (1st, 2nd, 3rd or o/d gear).
Then the ecm compares the actual gear with the shift schedule in the ecm memory
to detect the mechanical
trouble of the shift solenoid valves, th ...
Basic inspection
When the malfunction is not confirmed in the dtc check, troubleshooting
should be carried out in all the
possible circuits considered as causes of the problem. In many cases, by
carrying out the basic engine check
shown in the following flowchart, the location causing the problem can be found ...
Brake fluid
■ Checking fluid level
The brake fluid level should be between the “MAX” and “MIN” lines on the tank.
■ Adding fluid
Make sure to check the fluid type and prepare the necessary item.
1 Slide and lift up the rubber strip to partially remove it as shown.
2 Disconnect the claws a ...
