Fault Condition: Management System (EMS) Module senses a significant difference between the engine speed calculated from the CAM Speed Sensor signal and the engine speed calculated from the Crank Speed Sensor, the EMS Module will turn on the Electronic Malfunction Light, and code SID 21 will set. If the signals return to normal, the code will become inactive. The engine must be running to set an active CAM Speed Sensor fault code. Note: Electrical problems can cause this fault to be generated, and electrical diagnostics are provided in this section. Mechanical problems can also cause temporary or permanent speed signal...

Fault Condition: The Electronic Malfunction Lamp (EML) will turn on and code SID 211 will set when the reference voltage to the Fuel Pressure Sensor, Crankcase Pressure Sensor and the Oil Pressure Sensor is less than 4.5 volts or greater than 5.5 volts. If the voltage returns to 4.5 volts to 5.5 volts, the fault will become inactive. Possible repairs: Turn the ignition key OFF first. 1) Check if code SID 211 is set. Check if any other code is also set. If any other code code is set, go to the diagnostic routine for the specific code. If code...

Fault Condition: If the Engine Management System (EMS) Module calculates a significant difference between the Crank Speed Sensor input signal and the CAM Speed Sensor input signal, the EMS Module will turn on the Electronic Malfunction Lamp (EML) and SID 22 will set. If the engine speed signals agree, the fault will become inactive. The engine and tachometer will continue to operate when SID 22 is set because the EMS Module will use the CAMSpeed Sensor signal to calculate engine speed. Note: Electrical problems can cause this fault to be generated, and electrical diagnostics are provided in this section. Mechanical...
