INSPECTION OF CAM POSITION SENSOR

NE Pickup    G1 Pickup    G2 Pickup

1.  INSPECT AIR GAPS
Using a feeler gauge, measure the gap between the signal
rotor and pickup coil projection.
Air gap:  0.2 — 0.4 mm (0.008 — 0.016 in.)
If the gap is not within specification, replace the cam po-
sition sensor.

2.  INSPECT PICKUP COILS
Using an ohmmeter, check resistance of the pickup coil.
G1 pickup coil resistance:
  G1 — G⊖   140 — 180 Ω
G2 pickup coil resistance:
  G2 — G⊖   140 — 180 Ω
NE pickup coil resistance:
  NE — G⊖   140 — 180 Ω
If the resistance is not within specification, replace the cam
position sensor.
