1997 Buick Riviera Camshaft Position (CMP) Sensor Performance

Download 1997 Buick Riviera | Aurora, Riviera (VIN G) Service Manual DTC P0341 Camshaft Position (CMP) Sensor Performance. Circuit Description The camshaft position PCM input is produced by the ignition control module. The ICM produces the camshaft position PCM input by filtering the camshaft position (CMP) sensor pulses when the engine is running and CKP sync pulses are also being received. The PCM uses the camshaft position PCM input pulses to initiate sequential fuel injection and to determine crankshaft position for the misfire diagnostic. The PCM constantly monitors the number of pulses on the camshaft position PCM input circuit and compares the number of camshaft position PCM input pulses to the number of 18X reference pulses and the number of 3X reference pulses being received. If the PCM receives an incorrect number of pulses on the camshaft position PCM input circuit, DTC P0341 will set and the PCM will initiate injector sequence without the camshaft position PCM input with a one in six chance that injector sequence is correct.… Read More

Ford Mustang Fuel Injection Conversion

Download These instructions will provide the basic and necessary information to allow a carbureted 302 to be converted to SEFI Fuel Injection. There are several different types of fuel injection conversions available, however, this instruction will concentrate on the High Output, MASS-AIR setups found on the 92-93 Ford Mustangs. There are two main advantages to using this type of setup. The first advantage is that the computer in the MASS-AIR system will automatically compensate for any engine modifications that have been done prior to the installation of the fuel injection system. The second advantage is that fuel is sent to each cylinder individually only during the appropriate firing cycle, meaning that fuel is sent sequentially to each cylinder only when the spark plug is ready to fire. This makes for an extremely efficient firing cycle . SEFI stands for Sequential Electronic Fuel Injection. This system is complex to be sure, therefore, this instruction is going to skip all the technical mumbo-jumbo, and focus on the bare essentials to install this system properly.… Read More
