The square wave patterns are uniform and are identical to one another. The patterns must be evenly spread apart and at the same height. The larger gap pattern (signature) after the shorter wave forms are used for cylinder identification (Crank signal) and the distance between the series of slots (trigger) on the camshaft pulley (cam signal). Any variation of the pattern will indicate an issue with the sensor, wiring, and trigger (target) wheel. CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install the PCM Pinout Box 8815 along with the Adapter 8815-1 to perform the diagnosis. With a lab scope, probe the CKP Signal circuit in the appropriate terminal of the PCM Pinout Box 8815. WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in possible serious or fatal injury. Start and allow the engine to run. Observe the lab scope screen. Compare the scope pattern with the ones in see scheme 2. Pattern indicates a clean (good) square wave form that is identical to what the cam and crank should be. The square wave patterns are uniformed and are identical to one another. Two pulses joined together in the same spot on target. Indicates damage to the target (trigger) on the flex plate or broke tooth, runout in the target or large air gap between the sensor and the target wheel. Wide air gap or intermittent connection. Early signature, predominately at high speed. Large air gap between the sensor and the target wheel. Missed pulse. Possible burr or light damage to target or incorrect lateral position of the crank sensor to target (trigger). NOTE: If any of the above (except pattern 1) is displayed on the lab scope repair as necessary. Was the square wave found to match any of the above except pattern 1? Yes Repair as necessary. NOTE: A battery disconnect must be performed to clear the Cam Crank Synchronization Events. Perform the PCM VERIFICATION TEST. Refer to «DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure»(ref-353603-S03528494482010011200000). No Replace the Crankshaft Position Sensor.
