Fault Condition: If the EMS Module detects an open, short to ground or short to voltage in the Turbo Speed Sensor signal circuit, the Electronic Malfunction Lamp (EML) will turn ON and PID 103 will set. PID 103 will also set if the turbocharger wheel speed is not within the predetermined limits at a given engine speed. A fault is logged if the measured turbocharger speed is 25% or more lower than the target wheel speed for the measured boost. The speed must be low for approximately 5 seconds. The engine must be running for the diagnostic to take place...

Fault Condition: The Electronic Malfunction Lamp (EML) will turn on and PID 105 will set when the EMS Module senses that the Boost Pressure and Temperature Sensor signal voltage is less than 0.1 volts or greater than 4.55 volts. If the Boost Air Pressure/Temperature Sensor voltage is between 0.1 volts and 4.55 volts, the fault will become inactive. Possible repairs: Turn the ignition key OFF first. 1) Disconnect the Boost Air Pressure/Temperature Sensor connector. Measure the resistance between pins 1 and 2 of the Boost Air Pressure/Temperature Sensor with the ambient air temperature between 32° and 203°F (0° and 95°C)....

Fault Condition: The Electronic Malfunction Lamp (EML) will turn on and PID 105 will set when the EMS Module senses that the Boost Pressure and Temperature Sensor signal voltage is less than 0.1 volts or greater than 4.55 volts. If the Boost Air Pressure/Temperature Sensor voltage is between 0.1 volts and 4.55 volts, the fault will become inactive. If both PID 105 FMI 5 is present, there may be intermittent or total loss of the ground at connector A pin 11 of the EMS Module. Possible repairs: Turn the ignition key OFF first. 1) Disconnect the Boost Air Pressure/Temperature Sensor...

Fault Condition: The Ambient Pressure Sensor is shorted to another circuit. If the code is active, attempt to clear the code from memory and check if the code resets. If PID 108 resets, replace the Engine Management System (EMS) Module and retest the system.
