TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L>

13B-535

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.
