***UPDATED BY TSB# EN91-007, JUNE 1991

1. Disconnect the wiring connector near the camshaft position sensor.

Pick Up Coil Connector:





2. Connect one end of an ohmmeter to the G1 terminal. Connect the other end to the G- terminal.

G1 Pickup Coil Resistance: 130 - 210 ohms

3. Connect one end of an ohmmeter to the G2 terminal. Connect the other end to the G- terminal.

G2 Pickup Coil Resistance: 130 - 210 ohms

4. Connect one end of an ohmmeter to the NE terminal. Connect the other end to the G- terminal.

NE Pickup Coil Resistance: 130 - 210 ohms

Pick Up Coil Air Gap:





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

Air Gap: 0.008 - 0.016 in (0.2 - 0.4 mm)

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