CKP sensor is located inside distributor. If a fault is present in CKP sensor, Code 11 may be set in ECM memory. If Code 11 is set, perform appropriate CODE 11 (CKP SENSOR) in appropriate G - TESTS W/ CODES article in the ENGINE PERFORMANCE section below.
- TESTS W/CODES - 1.6L
- TESTS W/CODES - 2.0L
To test CKP sensor, remove distributor. Leave wiring harness connected. Using a voltmeter, connect negative lead to ground and alternately connect positive lead to 1-degree signal terminal and 120/180-degree signal terminal. See CKP SENSOR INPUT SIGNAL TERMINALS table. See Fig 1 and Fig 2 .
Measure voltages at both terminals while rotating distributor by hand. Voltage should fluctuate 0-5 volts. If either voltage signal does not fluctuate 0-5 volts, check harness for short or open circuit. If no problems are found, replace CKP sensor.

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.
