• Q: How is the Crankshaft Position Sensor System Variation Learn Procedure Performed After Engine Repairs on 2006 Chevrolet Cobalt?

  A: It is always recommended to perform the Crankshaft position (CKP) system variation learn procedure after undergoing an engine replacement, engine control module (ECM) replacement, crankshaft damper replacement, crankshaft replacement, ckp replacement, or any engine repair that interferes with the Crankshaft to ckp sensor relationship regardless of the occurrence of dtcs such as p0315. A scan tool has to be used to track component signals such as ckp sensor activity, camshaft position (CMP) signal activity, and engine coolant temperature (ECT). If the ect is not warm enough, youquote "idle the engine until the temperature is correct. First, watch the ecm for dtcs; in the case of any other dtcs, except p0315, refer to the specific dtc list. Choose the ckp system variation learn procedure in the special functions menu of the scan tool and follow the following steps: observe the fuel cut off for the applicable engine, block the drive wheels, set the parking brake, place the transmission in park or neutral, turn the air conditioning (A/C) off, cycle the ignition from off to on, applied and held the Brake Pedal, start and idle the engine, and the filed the wot (wide open throttle) but not exceed the calibrated fuel cut off rpm value. Release the throttle as soon as possible if the value is exceeded, as well as when the fuel is cutoff. While learning, release throttle instantly as you can feel that the engine is starting to decelerate and leave it to the control of the engine control to the operator. The scan tool will show: learn status: learned this ignition; learned this ignition; if dtc p0315 ran and passed, the procedure is complete. If it did not, or did not run, see dtc p0315, and if there are other dtcs on this tool, see the table courtesy note located in the front of the tool. Finally, turn off ignition 30 seconds after reaching the learn procedure successfully.
