Signal Rotor Air Gap
1) Remove distributor cap and rotor.
2) Using thickness gauge, measure air gap, between signal rotor
tooth (2) and CMP sensor (generator) (1).
Signal rotor air gap “a”: 0.2 – 0.4 mm (0.008 – 0.016 in.)
3) If gap is out of specification, loosen CMP sensor (signal genera-
tor) securing screws (3). Move CMP sensor (generator) and ad-
just gap to specification. After adjustment, tighten securing
screws and recheck gap.
NOTE:
Check to make sure that CMP sensor (signal generator)
tooth is free from any metal particles.
4) Install distributor cap and rotor.
CMP Sensor Resistance
1) Disconnect distributor lead wire coupler (1).
2) Measure resistance of CMP sensor by using ohmmeter.
CMP sensor resistance:
185 – 275
(at -10–50
C/ 14–122
F)
240 – 325
(at 50–100
C/122–212
F)
3) If resistance is out of specification, replace CMP sensor as fol-
lows.
4) Remove distributor cap and rotor.
5) Remove CMP sensor securing screws.
6) Replace CMP sensor.
7) Adjust signal rotor air gap to specifications as previously out-
lined.
8) Install rotor, distributor cap seal and cap.
