1. Install a scan tool.
2. Turn OFF the ignition for 30 seconds.
3. Start the engine.

1. Turn OFF the ignition.
2. Disconnect the in-line harness connector from
the cylinder head cover case.
3. Measure the resistance of the charge voltage
circuit across the female side connector.
4. Measure the resistance of the charge voltage
circuit across the male side connector.
Are both resistance readings less than the
specified value (either of reading is out of
specified value will not set this DTC)?
1.0Ω

1. Connect a DMM between the cylinder #2
charge voltage circuit and a known good
ground.
2. Turn ON the ignition, with the engine OFF.
Is the DMM voltage less then the specified
value?
1.0 volt
Go to Step 5 Go to Step 10
5
Connect a DMM between the cylinder #2 solenoid
control circuit and a known good ground.
Is the DMM voltage less than the specified
value?
16.0 volts
Go to Step 6 Go to Step 11

Is the DMM voltage more than the specified
value at Step 5?
12.0 volts
Go to Step 7 Go to Step 12

1. Inspect for an intermittent and for poor
connections at the in-line harness connector.
2. Repair the connection(s) as necessary.
Did you find and correct the condition?

Go to Step 17 Go to Step 8
8
1. Remove the cylinder head cover. Refer to
Cylinder Head Cover in Section 1B Engine
Mechanical.
2. Inspect the fuel injector harness for loose
injector terminal nuts, objects touching injector
terminals.
3. Inspect for an intermittent and for poor
connections at the in-line harness connector.
4. Repair the connection(s) as necessary.
Did you find and correct the condition?

Go to Step 17 Go to Step 13
9
Repair the open circuit or high resistance on the
charge voltage circuits between the ECM and the
in-line harness connector, then between the in-line
harness connector and the fuel injector terminal.
Did you complete the repair?
