Test CID2 - Cylinder Identification No. 2

NOTE: Enter this test only when Code 04 is displayed during SELF-TEST procedures, or when directed here from another CIRCUIT TEST. This test is intended to diagnose only the following: CID1 and CIDREF.

CIRCUIT PIN IDENTIFICATION (CID2)

Circuit	Breakout Box Pin	ECA Pin
2.2L Turbo
CID2	30	3H
CIDREF	13	3F

NOTE: The CID is incorporated with the Crankshaft Position Sensor (CPS) inside the distributor.

1) Checking System Integrity Visually check all wiring, connectors and components for evidence of damage, shorting or looseness. If a fault is found, repair as necessary. If no fault is found, go to step 2).

2) Checking CID2 Circuit Resistance Turn ignition off. Install breakout box, leaving ECA disconnected. Set DVOM on 1000-ohm scale. Check resistance between CID2 and CIDREF test pins. If resistance is 210-260 ohms, go to step 3). If resistance is not as specified, go to step 4).

3) Checking CID2 Circuit Voltage With ECA disconnected, measure voltage between test pins of CID2 and CIDREF breakout box while cranking engine. If voltage is not 0.6-0.8 volt, replace CID2 sensor. If voltage is 0.6-0.8 volt, circuit is okay. Repeat KOEO self-test. See SELF-TEST. If no other faults or codes are found, replace ECA.

4) Checking CID1 Sensor Resistance With key off, disconnect distributor connector. Measure resistance between CID2 (Red wire) and CIDREF (White wire) terminals. If resistance is 210-260 ohms, repair CID2 or CIDREF circuit from distributor to ECA. If resistance is not 210-260 ohms, replace CID2 sensor.
