Crankshaft Position System Variation Learn

Note. The Crankshaft Position Variation Learn procedure is also required when the following service procedures have been performed, regardless of whether DTC P0315 is set: An engine replacement An engine control module (ECM) replacement A crankshaft balancer replacement A crankshaft replacement A crankshaft position sensor replacement Any engine repairs which disturb the crankshaft to crankshaft position sensor relationship.

Note. The ECM monitors certain component signals to determine if all the conditions are met to continue with the Crankshaft Position Variation Learn procedure.

1. Ignition ON, observe the DTC information with a scan tool. Verify no other DTCs are set, except DTCs P0300-P0304, or P0315. If DTCs are set, except DTCs P0300-P0304, or P0315, refer to «Diagnostic Trouble Code (DTC) List - Vehicle»(/chevrolet/captiva/i-2011-2013/remont/oem-general-information/#vehicle-diagnostic-information__diagnostic-trouble-code-dtc-list) for further diagnosis.
2. Select the Crankshaft Position Variation Learn Procedure with a scan tool and perform the following: NOTE: Close the hood. NOTE: The engine must be at operating temperature. Block drive wheels. Set parking brake. DO NOT apply brake pedal. Turn the air conditioning (A/C) OFF. When directed, apply and hold brake pedal for the duration of the procedure. Ignition ON, engine running at operating temperature. The vehicle must remain in Park or Neutral. NOTE: While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is returned to the operator and the engine responds to throttle position after the learn procedure is complete. Accelerate to wide open throttle (WOT) and release when the fuel cut-off occurs.
3. The scan tool displays: Learn Status: Learned this Ignition.
4. Verify DTC P0315 ran and passed This Ignition Cycle. If DTC P0315 failed or did not run This Ignition Cycle, or another DTC is present, refer to «Diagnostic Trouble Code (DTC) List - Vehicle»(/chevrolet/captiva/i-2011-2013/remont/oem-general-information/#vehicle-diagnostic-information__diagnostic-trouble-code-dtc-list) for the applicable DTC that set.
5. Once the Crankshaft Position Variation Learn procedure has successfully completed, and in order to store the crankshaft position variation values in the ECM, turn OFF the ignition and verify all vehicle systems are OFF. This may take up to 2 minutes.

Description

The engine control module (ECM) learns the airflow through the throttle body to ensure the correct idle. The learned airflow values are stored within the ECM. These values are learned to adjust for production variation and will continuously learn during the life of the vehicle to compensate for reduced airflow due to throttle body coking. Anytime the throttle body airflow rate changes, for example due to cleaning or replacing, the values must be relearned.

An engine that had a heavily coked throttle body that has been cleaned or replaced may take several drive cycles to learn out the coking. To accelerate the process, the scan tool has the ability to reset all learned values back to zero. A new ECM will also have values set to zero.

The idle may be unstable or a DTC may set if the learned values do not match the actual airflow.

Spark Plug Usage

1. Ensure that the correct spark plug is installed. An incorrect spark plug causes driveability conditions. Refer to the Electronic Parts Catalog.
2. Ensure that the spark plug has the correct heat range. An incorrect heat range causes the following conditions: Spark plug fouling - colder plug Pre-ignition causing spark plug and/or engine damage - hotter plug

Spark Plug Inspection

1. Inspect the terminal post (1) for damage. Inspect for a bent or broken terminal post (1). Test for a loose terminal post (1) by twisting and pulling the post. The terminal post (1) should NOT move.
2. Inspect the insulator (2) for flashover or carbon tracking, soot. This is caused by the electrical charge traveling across the insulator (2) between the terminal post (1) and ground. Inspect for the following conditions: Inspect the spark plug boot for damage. Inspect the spark plug recess area of the cylinder head for moisture, such as oil, coolant, or water. A spark plug boot that is saturated causes arcing to ground.
3. Inspect the insulator (2) for cracks. All or part of the electrical charge may arc through the crack instead of the electrodes (3, 4).
4. Inspect for evidence of improper arcing. Measure the gap between the center electrode (4) and the side electrode (3) terminals. Refer to «Ignition System Specifications»(/chevrolet/captiva/i-2011-2013/remont/testing-diagnostics/#engine-controlsfuel-24l-specifications__ignition-system-specifications) . An excessively wide electrode gap can prevent correct spark plug operation. Inspect for the correct spark plug torque. Refer to «Ignition System Specifications»(/chevrolet/captiva/i-2011-2013/remont/testing-diagnostics/#engine-controlsfuel-24l-specifications__ignition-system-specifications) . Insufficient torque can prevent correct spark plug operation. An over torqued spark plug, causes the insulator (2) to crack. Inspect for signs of tracking that occurred near the insulator tip instead of the center electrode (4). Inspect for a broken or worn side electrode (3). Inspect for a broken, worn, or loose center electrode (4) by shaking the spark plug. A rattling sound indicates internal damage. A loose center electrode (4) reduces the spark intensity. Inspect for bridged electrodes (3, 4). Deposits on the electrodes (3, 4) reduce or eliminates the gap. Inspect for worn or missing platinum pads on the electrodes (3, 4) If equipped. Inspect for excessive fouling.
5. Inspect the spark plug recess area of the cylinder head for debris. Dirty or damaged threads can cause the spark plug not to seat correctly during installation.

Spark Plug Visual Inspection

1. Normal operation-Brown to grayish-tan with small amounts of white powdery deposits are normal combustion by-products from fuels with additives.
2. Carbon Fouled-Dry, fluffy black carbon, or soot caused by the following conditions: Rich fuel mixtures Leaking fuel injectors Excessive fuel pressure Restricted air filter element Incorrect combustion Reduced ignition system voltage output Weak coils Worn ignition wires Incorrect spark plug gap Excessive idling or slow speeds under light loads can keep spark plug temperatures so low that normal combustion deposits may not burn off.
3. Deposit Fouling-Oil, coolant, or additives that include substances such as silicone, very white coating, reduces the spark intensity. Most powdery deposits will not effect spark intensity unless they form into a glazing over the electrode.
