Toyota Tacoma 2015-2018 Service Manual: Inspection

INSPECTION

PROCEDURE

1. INSPECT FUEL INJECTOR ASSEMBLY

(a) 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 resistance is not as specified, replace the fuel injector assembly.

(b) Inspect the injection volume.

CAUTION:

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.

(c) Disengage the 2 claws and remove the No. 2 fuel pipe clamp.

(d) Remove the No. 1 fuel pipe clamp.

(e) Disconnect the fuel tube sub-assembly (engine compartment right side) (See page ).

(f) Connect SST to the fuel pipe (vehicle side).

NOTICE:

  • 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.

(j) Check that SST (clamp) and SST (adapter) cannot be easily separated.

(k) Install a vinyl tube to the fuel injector assembly.

NOTICE:

Install a suitable vinyl tube onto the fuel injector assembly to contain the gasoline spray.

(l) Set the fuel injector assembly in a graduated cylinder.

(m) Operate the fuel pump (See page ). ).

(n) Connect SST (EFI inspection wire I) to the fuel injector assembly and battery for 15 seconds, and measure the injection volume with the graduated cylinder. Test each fuel injector assembly 2 or 3 times.

*a

SST (EFI Inspection Wire I)

SST: 09842-30090

Standard injection volume:

67 to 81 cc (4.1 to 4.9 cu.in.) per 15 seconds

Difference between each injector:

14 cc (0.9 cu.in.) or less

NOTICE:

  • 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 injector assembly side.

If the injection volume is not as specified, replace the fuel injector assembly.

(o) Check for leakage.

(1) Disconnect the tester probes of SST (EFI inspection wire I) from the battery and check for fuel leaks from the fuel injector assembly.

Standard fuel drop:

1 drop or less in 20 minutes

If there is excessive leakage, replace the fuel injector assembly.
