DTC 13

CODE 13 - G, NE SIGNAL CIRCUIT (NO. 2)

Circuit Description

The IIA in the Engine Control System contains two pickup coils (G and NE). The G signal informs the ECM of the standard crankshaft angle. The NE signal informs the ECM of the crankshaft angle and the engine speed.




Detecting Condition

Diagnostic Procedure

This code indicates that a momentary interruption of the G, NE signal from the IIA to the ECM has occurred, but that it is 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 IIA connector and the NE terminal of the ECM connector must therefore be checked for the following:

1. Loose connectors
2. Dirty connector terminals
3. Loose connector terminals
