STEP 7. Check the injector.
(1) Disconnect the injector connector.
(2) Measure the resistance between each injector side
connector terminal No. 1 and No. 2.
Standard value: 13
− 16 ohms [at 20°C (68°F)]
Q: Is the resistance between 13 and 16 ohms?
YES : Go to Step 8.
NO : Replace the faulty injector. Then go to Step 13.

STEP 10. Check for harness damage between injector
connector and ECM connector <M/T> or PCM connector
<A/T>.
a. Check the harness wire between injector connector B-01
(terminal No. 2) and ECM connector C-51 (terminal No. 1)
<M/T> or PCM connector C-52 (terminal No. 1) <A/T> when
checking No. 1 cylinder.
b. Check the harness wire between injector connector B-02
(terminal No. 2) and ECM connector C-51 (terminal No. 9)
<M/T> or PCM connector C-52 (terminal No. 9) <A/T> when
checking No. 2 cylinder.
c. Check the harness wire between injector connector B-05
(terminal No. 2) and ECM connector C-51 (terminal No. 24)
<M/T> or PCM connector C-52 (terminal No. 24) <A/T>
when checking No. 3 cylinder.
d. Check the harness wire between injector connector B-06
(terminal No. 2) and ECM connector C-51 (terminal No. 2)
<M/T> or PCM connector C-52 (terminal No. 2) <A/T> when
checking No. 4 cylinder.
e. Check the harness wire between injector connector B-26
(terminal No. 2) and ECM connector C-51 (terminal No. 10)
<M/T> or PCM connector C-52 (terminal No. 10) <A/T>
when checking No. 5 cylinder.
f. Check the harness wire between injector connector B-25
(terminal No. 2) and ECM connector C-51 (terminal No. 25)
<M/T> or PCM connector C-52 (terminal No. 25) <A/T>
when checking No. 6 cylinder.
Q: Is the harness wire in good condition?
YES : Go to Step 11.
NO : Repair it. Then go to Step 13.
