Circuit Description

The distributor contains 3 pick-up coils; G1, G2 and NE signal coils. The G1 and G2 signal pick-up coils send ECM standard crankshaft position. The NE signal pick-up coil sends the ECM crankshaft angle and engine speed. Code is set when there is no G1, G2 or NE signal to ECM within 2 seconds after cranking and/or open G signal to ECM. Possible causes are:

• G and NE open or short circuit.
• Distributor pick-up coil(s).
• STA open or short circuit.
• ECM.
