GM LT1/LT4 5.7 liter engine (1992-1996) Optical Spark Distributor system (tune-up) Pt 1/2
The video we expose the internal of the Chevrolet LT1 front engine mount electronic distributor (hi-voltage).Part of a Complete Tune-up processor. HERE we explain the inner workings of Hi-Voltage Distribution Part. This component can be found on the corvette,caprice,GMC trucks,Roadmaster,Cadillac. Subject: theory and testing of Opti-spark(optical) systems Contributing Source: General Motor service manuals and training materials The General Motor Opti-spark ignition system is used on 1994-96 4.3-liter L99 (VIN W) V-8 engine and on 1992-97 5.7-liter LT1 (VIN P) V-8 engines. The Opti-spark distributor is mounted on the front of the engine block, above the crankshaft. The distributor is driven by the camshaft. Opti-spark system rely on two optical cam position (CMP) sensors mounted inside the distributor. Beginning in 1996, Opti-spark equipped vehicles also included a crankshaft position (CKP) sensor mounted at the bottom of the timing cover, The PCM uses this CKP sensor only for misfire diagnosis, not ignition timing. This sensor is not part of the Opti-spark system. The Opti-spark CMP sensor provide signal to the PCM (Powertrain Control Module) for ignition timing control. These sensors detect slots in the crank-driven signal disk. One CMP sensor detects 360 equally spaced slots per camshaft revolution, for high-resolution timing control. The other CMP sensor detect eight signal disc slots, the CMP reference signal toggle between 0.0 and 5.0 volts. The PCM compares the two CMP signal to determine if one of the inputs is not being received.

GM LT1/LT4 5.7 liter engine (1992-1996) Optical Spark Distributor system (tune-up) Pt 2/2
Part of a Complete Tune-up processor for the Chevrolet LT1(VIN P) and L99(VIN W). HERE we inspect all the moving a friction parts for functionality. Opti-spark trouble codes 1992-95 * Code 16 - sets if PCM detects high-resolution timing signal, but no low resolution spark signal. Engine will not start while code 16 is set. * Code 36 - sets if PCM detect low resolution spark plug signal, but no high resolution timing signal. Engine will start while code 36 is set, but performance and fuel economy will be adversely affected. * Code 41 - sets if PCM senses the ignition control circuit is open, or shorted to voltage while cranking. Engine will not start while code 41 is set. * Code 42 - sets if PCM senses a grounded ignition circuit while cranking. Engine will not start while code 42 is set. Opti-spark OBD-II diagnostic trouble codes * P0323 - sets if the PCM detect an interruption in either the low or high resolution signal. * P0335 - sets if the PCM receives no signal from the crankshaft position (CMP) sensor or if the signals from the CMP sensor and low resolution distributor are significantly asynchronous. * P0336 - stes if the PCM sensor and low resolution distributor signal are only slightly asynchronous. * P0372 - sets if the PCM sensor and low resolution pulses but no high resolution pulses. * P1351 - sets if the PCM detects voltage on the ignition control circuit that exceeds 4.6 volts while cranking. * P1361 - sets if the PCM detect 84 crankshaft revolution without any ignition control activity during cranking. * P1371 - stes if the PCM detects too many high resolution pulses before detecting any low resolution pulses. Opti-spark EST circuit. The PCM combines the camshaft position information with other system parameters to calculate the required spark advance and coil dwell. Opti-spark ignition system do not have a bypass circuit in the ignition module or the PCM. All ignition timing is controlled by the PCM. The PCM signalz the ignition module through the EST circuit by grounding the primary circuit that supplies current to the ignition coil, aopti-spark system do not have a base timing adjustment. Timing advance and retart is PCM controlled and factory set. Opti-spark ignition control module (ICM) and Coil Assembly The Opti-spark ignition control module (ICM) and high-output coil assembly are mounted as one unit. The resistance specification for the coil are: * PRIMARY - 0.3 to 1.3 ohms *SECONDARY - 5.0 to 7.0 ohms Found on Chevy Camaro, caprice and corvette,Pontiac Firebird Trans-am,Buick Roadmaster Wagon,Cadillac
