Test A4 - Cylinder Identification No. 2

Fig 1: CID2 Circuit & Connector Identification

NOTE: Enter this test only when Code 04 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.

CID2 CIRCUIT PIN IDENTIFICATION

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, 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 key off and install breakout box. Leave ECA disconnected. Set VOM on 1000-ohm scale. Check resistances between CID2 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 With key off, disconnect distributor connector. Set VOM on 1000-ohm scale. Measure resistance between CID2 and CIDREF terminals. If resistances is not 210-260 ohms, replace CID2 sensor. If resistances is 210-260 ohms, repair CID2 (Red) or CIDREF (White) circuit from distributor to ECA.

4) Checking CID2 Circuit Voltage Disconnect distributor harness connector. Measure voltage between CID2 and CIDREF test pin while cranking engine. If voltage is 0.6-0.8 volt, circuit is okay. If not, replace CID2 sensor.
