Signal Rotor Air Gap
1. Remove distributor cap and rotor.
2. Using thickness gauge, measure air gap, between signal rotor tooth and CMP sensor (generator).
Signal rotor air gap "a": 0.2 - 0.4mm (0.008 - 0.016in.)
3. If gap is out of specification, loose CMP sensor (signal generator) securing screws. Using blade (-) screw driver, move CMP sensor (generator) and adjust 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 (Pickup Coil) Resistance
1. Disconnect distributor lead coupler.
2. Measure resistance of pickup coil by using ohmmeter.
Pickup coil resistance:
185 - 275 Ohms at -10°C to 50°C (-14° to 122°F)
240 - 325 Ohms at 50°C to 100°C (122° to 212°F)
3. If resistance is out of specification, replace CMP sensor (signal generator) as follows.
4. Remove distributor cap and rotor.
5. Remove CMP sensor (signal generator) securing screws and lead wire clamp screws.
6. Replace CMP sensor (signal generator).
7. Adjust signal rotor air gap to specifications as previously outlined.
8. Install rotor, distributor cap seal and cap.
1. Remove distributor cap and rotor.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
