Crankshaft Position Sensor: Testing and Inspection

INSPECTION





1. Disconnect the wiring connector near the distributor.
2. Connect one end of an ohmmeter to the G1 terminal at the distributor. Connect the other end to the G- terminal. G1 Pickup Coil Resistance:

Cold (14° - 122°F): 125 - 200 ohms
Hot (122° - 212°F): 160 - 235 ohms

3. Connect one end of an ohmmeter to the G2 terminal at the distributor. Connect the other end to the G- terminal. G2 Pickup Coil Resistance:

Cold (14° - 122°F): 125 - 200 ohms
Hot (122° - 212°F): 160 - 235 ohms

4. Connect one end of an ohmmeter to the NE terminal at the distributor. Connect the other end to the G- terminal. NE Pickup Coil Resistance:

Cold (14° - 122°F): 155 - 250 ohms
Hot (122° - 212°F): 190 - 290 ohms








5. Using a non-magnetic feeler gauge, measure the gap between the signal rotor and pickup coil projection.

G1 Air Gap: 0.2 - 0.5 mm (0.008 - 0.020 in)
G2 Air Gap: 0.2 - 0.5 mm (0.008 - 0.020 in)
NE Air Gap: 0.2 - 0.5 mm (0.008 - 0.020 in)

NOTE: The air gap is not adjustable. If any of the above tests reveal a pick-up coil outside specifications, replace the distributor assembly.
