CIRCUIT DESCRIPTION
Refer to G, NE signal circuit (No. 1) on page EG1±336, 339.
No G signal to ECM while N E signal is input 4
times to ECM when engine speed is between
500 rpm and 4,000 rpm.
* NE signal does not pulse 12 times to ECM
during the interval between G1 and G2 pulses.* No NE signal to ECM for 0.1 sec. or more at
1,000 rpm or more.No NE signal to ECM for 0.3 sec. or more at
1,500 rpm or more.

DTC No.
DIAGNOSIS
This code indicates that a momentary interruption of the G, N E signal from the distributor to the
ECM has occurred, but that it is returned to normal. Note that although this problem may not nec-
essarily appear at the time of inspection, it cannot be ignored because this diagnostic trouble code
is output, indicating that there is or was a malfunction in the G, NE signal circuit; this ªmalfunctionº
is usually a loose connector.
The distributor connector and the N E terminal of the ECM connector must therefore be checked
for the following:
1. Loose connectors
2. Dirty connector terminals
3. Loose connector terminals

Disconnect the high±tension cord from the distributor, hold its end about 12.5 mm (11 /2º)
from the ground, see if spark occurs while the engine is being cranked.
Spark should be generated.
To prevent excessive fuel injected from the injectors during this check, don't crank the
engine for more than 1 ± 2 seconds at a time.
(1) Disconnect igniter connector.
(2) Remove glove compartment.
(See page EG1±234).
(3) Turn ignition switch on.
Measure voltage between terminal IGF of engine
control module connector and body ground.
Voltage: 4.5 ~ 5.5 V
Check for open and short in harness and connector in IGF signal
circuit between engine control module and igniter (See page IN±31).
Disconnect igniter connector and check voltage between terminal
IGF of engine control module connector and body ground.
Check and replace engine control module.Repair or replace harness or connector.
