Pinpoint Test C KOER Code 213: Timing Incorrect, Spout Open,

POOR FUEL ECONOMY OR POOR DRIVEABILITY

1. Check Base Timing  Check ignition timing. See IGNITION TIMING in the appropriate ADJUSTMENTS - 2.0L article. If ignition timing is within 3 degrees of base timing specification, go to next step. If timing is not within 3 degrees of base timing specification, adjust timing.
2. Check Spark Advance  Turn ignition off. Reconnect SPOUT in-line connector. Ensure engine is at normal operating temperature. Start engine and allow it to idle. Check ignition timing. If timing is 6-18 degrees BTDC (Probe) or more than 18 degrees BTDC (all others), problem is not ignition related. See the TESTS W/O CODES - EEC-IV (2.0L) article for more symptom diagnosis. If timing is not as specified, go to next step.
3. Check For Good SPOUT To ICM  Connect DI Diagnostic Cable (007-00097) to EEC-IV Breakout Box (T83L-50-EEC-IV), negative battery terminal and ICM. See Figure. Leave B+ lead disconnected. Ensure PIP OPEN/NORMAL/SPOUT OPEN switch is in SPOUT OPEN position. Apply DI overlay on breakout box. Set DVOM on AC scale. Start engine and allow to idle. Measure voltage between J7 (B-) and J10 (SPOUT). If AC voltage is 3.0-8.5 volts, replace ICM. If AC voltage is not 3.0-8.5 volts, go to next step.
4. Check For SPOUT Open In Harness  Turn ignition off. Disconnect PCM wiring harness connector. Disconnect diagnostic connector from ICM. Leave ICM wiring harness connector connected to diagnostic cable. Measure resistance between J10 (SPOUT) at breakout box and terminal No. 36 (SPOUT) at PCM wiring harness connector. If resistance is less than 5 ohms, replace PCM. If resistance is 5 ohms or more, repair open SPOUT circuit between PCM and ICM wiring harness connector.
