Inspection [08/2015 - 08/2018]: Procedure
WARNING: This page is about a different car, the 2018 Toyota Sequoia, 2017 Toyota Sequoia, and 2016 Toyota Sequoia. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT FUEL INJECTOR ASSEMBLY
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 11.6 to 12.4 Ω If the result is not as specified, replace the injector assembly.
- Inspect the injection volume.WARNING:
- This test involves high-pressure fuel and electricity. Take all precautions regarding safe handling of both the fuel and the electricity.
- Perform this test in a safe area, and avoid any sparks or flames.
- Do not smoke.
Remove the fuel pipe clamp.
- Disconnect the No. 1 fuel pipe sub-assembly (for quick type B) (Refer to PRECAUTION [08/2015 - 08/2018] ).
Connect SST to the fuel pipe (the vehicle side).
- SST: 09268-31014
- 09268-41500
- 09268-41700
- 95336-08070
- SST: 09268-31014
- Install the O-ring to the fuel injector.
- Install SST and a tube to the fuel injector.
- SST: 09268-31014
- 09268-41300
- 09268-41500
- 09268-41600
- 09268-41700
WARNING:Install a strong rubber tube onto the injector to prevent gasoline from splashing.
- SST: 09268-31014
Pass SST (tie band) through the loop on the handle of SST (clamp) to secure SST (clamp) to SST (adapter).
- SST: 09268-31014
- 09268-41800
NOTE:- As SST (tie band) does not completely prevent SST (clamp) from becoming loose, do not subject the parts to any impacts while using them.
- Before using SST (tie band), make sure that there is no deterioration, damage or cracks. If there are any abnormalities, replace SST.
HINT:
When removing SST (tie band), disengage the lock.
- SST: 09268-31014
- Check that SST (clamp) and SST (adapter) cannot be easily separated.
Put the injector into a graduated cylinder.
- Operate the fuel pump (turn the ignition switch to ON).
- Connect SST (wire) to the injector and the battery for 15 seconds, and measure the injection volume with the graduated cylinder. Test each injector 2 or 3 times.
- SST: 09842-30090
Standard injection volume
97 to 118 cm3 (5.9 to 7.2 cu. in.) per 15 seconds
Difference between each injector
21 cm3 (1.3 cu. in.) or less
NOTE:- Make sure that SST (EFI inspection wire I) is securely connected.
- Always turn the voltage on and off on the battery side, not the fuel pump side.
If the injection volume is not as specified, replace the injector assembly.
- Check for leakage.
- Measure the resistance according to the value(s) in the table below.
