DTC 13 G, NE Signal Circuit (No.2)
CIRCUIT DESCRIPTION
The distributor in the Engine Control System contains 3 pick-up coils (G and NE (2)).
- The G signal informs the ECM of the standard camshaft position.
- The NE signals inform the ECM of the crankshaft position and the engine speed.
DIAGNOSIS
This code indicates that an intermittent problem with the G, NE signals from the distributor to the ECM has occurred, but that it has returned to normal. Note that although this problem may not necessarily 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 "malfunction" is usually a loose connector.
The distributor connector and the corresponding terminals of the ECM connector must therefore be checked for the following:
1. Loose connectors
2. Dirty connector terminals
3. Loose connector terminals
