Fault Condition: The Electronic Malfunction Lamp (EML) will turn on and PID 102 will set when the EMS Module senses that the Boost Pressure and Temperature Sensor signal voltage is less than 0.15 volts or greater than 4.75 volts. If the Boost Air Pressure/Temperature Sensor voltage is between 0.15 volts and 4.75 volts, the fault will become inactive. Possible repairs: Turn the ignition key OFF first. 1) Disconnect the Boost Air Pressure/Temperature Sensor. Disconnect Engine Management System (EMS) Module connector A. Check for continuity between pin 4 on the harness side of the Boost Air Pressure/Temperature Sensor and a good...

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...
