Test A3 - Cylinder Identification No. 1

Fig 1: CID1 Circuit & Connector Identification

NOTE: Enter this test only when Code 03 is displayed during QUICK TEST procedures or when directed here from another CIRCUIT TEST. This test is intended to diagnose only the following: CID1, CIDREF, VPWR, & distributor ground.

CID1 CIRCUIT PIN IDENTIFICATION

Circuit	Breakout Box Pin	ECA Pin
2.2L Turbo
CID1	28	3G
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, harnesses, connectors and components for evidence of damage, overheating, shorting or looseness. If a fault is found, repair as necessary. If no faults are found, go to next step.

2) Checking CID1 Circuit Resistance Turn ignition off and install breakout box. Leave ECA disconnected. Set VOM on 1000-ohm scale. Check resistances between CID1 and CIDREF test pins. If resistance is 210-260 ohms, go to step 4. If not, go to next step.

3) Checking CID1 Sensor Resistance Turn key off and disconnect distributor connector. Set VOM on 1000-ohm scale. Measure resistance between CID1 and CIDREF terminals. If resistances is not 210-260 ohms, replace CID1 sensor. If resistances is 210-260 ohms, repair CID1 (Green wire) or CIDREF (White wire) circuit from distributor to ECA.

4) Checking CID1 Circuit Voltage Disconnect distributor harness connector. Measure voltage between CID1 (Green) and CIDREF (White) test pin while cranking engine. If voltage is 0.6-0.8 volt, circuit is okay. If not, replace CID1 sensor.
