Circuit Description

The CMP sensors (G1 and G2 signal) consist of a signal plate and a pick-up coil. The G1 and G2 signal plates each have one tooth on the outer circumference and are built into the distributor. DTC is set when either no cranking or engine running signal is received by ECM from sensors. Possible causes are:

• CMP sensor open or short circuit.
• CMP sensor.
• Starter.
• ECM.
