Checking internal resistance

-- Using a multimeter, check the Fuel Injector -- electrical terminals 1 to 2 for resistance.

Specified value: 9.0 to 16.0 Ω (at approx. 20° C)

If the specified value was Not obtained: 

-- Replace the malfunctioning Fuel Injector --

-- Go to Final procedures

If the specified value was obtained: 

-- Remove the Engine Control Module (ECM) -J623-.

-- Using a multimeter, check the Fuel Injector -- electrical harness connector terminals to the Engine Control Module (ECM) -J623- electrical harness connector T60 terminals for an open circuit.

Component Fuel Injector -- electrical harness connector terminals Engine Control Module (ECM) -J623- electrical connector T60 terminals
Cylinder 1 Fuel Injector -N30- 2 2
Cylinder 2 Fuel Injector -N31- 2 5
Cylinder 3 Fuel Injector -N32- 2 3
Cylinder 4 Fuel Injector -N33- 2 4

Specified value: 1.5 Ω Max.

If the specified value was Not obtained: 

-- Check the wiring connection for an open circuit, short circuit to Battery positive or Ground

-- Check the wiring connection for damage, corrosion, loose or broken terminals.

-- If necessary, repair the faulty wiring connection.

-- Go to Final procedures

If the specified value was obtained: 

-- Replace the Engine Control Module -J623-.

Final procedures 

-- Install the engine cover with air filter.

After the repair work, the following work steps must be performed in the following sequence: 

  1. Check the DTC memory. Refer to DIAGNOSTIC MODE 03 - READ DTC MEMORY .
  2. If necessary, erase the DTC memory. Refer to DIAGNOSTIC MODE 04 - ERASE DTC MEMORY .
  3. If the DTC memory was erased, generate readiness code. Refer to READINESS CODE .
