I would assume that the CKP sensor in your D16Z6 Civic is probably in the distributor. Not the same as the OBD2 Accord posted above. If the CKP in the distributor goes bad that means you will need to replace the distributor.
There is a test procedure
• Disconnect the 8pin connector from the distributor
• Measure the resistance between sensor terminals B & F (ECU terminals B15 BLU/GRN wire & B16 BLU/YEL wire)
• If the resistance is not between 350Ω & 700Ω replace the distributor.
• If the resistance is between 350Ω & 700Ω - Check for continuity to body ground on both B & F terminals.
• Does continuity exist
Yes - replace distributor
• Test the ECU
