Volvo All Engines (2004 Emissions) Fault Code: PID 158 FMI 4 Battery Voltage
Posted by PerDiezel Solutions on
Fault Condition: Code PID 158 will set with an FMI 3 if the voltage rises above 19 volts (12 volt system) or above 36 volts (24 volt system). FMI 4 will set when the battery voltage falls below 9 volts (12 volt system) or below 17 volts (24 volt system). Damage to the modules and its components may occur with high battery voltages. Possible repairs: 1) Verify that code PID 158 is set. If code PID 158 is not set, wiggle the harness and connectors to try to set the code.2) Check the Failure Mode Identifier (FMI) using a diagnostic...
Volvo All Engines (2004 Emissions) Fault Code: PID 171 FMI 9 Ambient Air Temperature Status
Posted by PerDiezel Solutions on
Fault Condition: The Ambient Air Temperature Status code will set when a fault is detected in the Ambient Air Temperature Sensor, the J1507/J1708 Data Lines or the Instrument Cluster Module (ICM). Possible repairs: 1) Verify that code PID 171 is set. If code PID 171 is not set, wiggle the harness and connectors to try to set the code. Visually inspect the connectors and wires for poor connections.2) Is code MID 140 PID 171 set?If code MID 140 PID 171 is set, repair the code(s) MID 140 PID 171 first then retest the system.If only MID 128 PID 171 is...
Volvo All Engines (2004 Emissions) Fault Code: PID 172 FMI 4 Intake Air and Humidity Sensor
Posted by PerDiezel Solutions on
Fault Condition: The Electronic Malfunction Lamp (EML) will turn on and PID 172 will set when the Engine Management System (EMS) Module senses that the Intake Air Temperature Sensor signal voltage is less than 0.5 volts or greater than 4.9 volts for 1 second. If the Intake Air Temperature Sensor voltage returns to between 0.5 volts and 4.9 volts for more than 1 second, the fault will become inactive. Possible repairs: Turn the ignition key OFF first. 1) Disconnect the Intake Air Temperature and Humidity (IATH) Sensor connector. Measure the resistance between pins 3 and 4 of the Intake Air...

Volvo All Engines (2004 Emissions) Fault Code: PID 175 FMI 0 Engine Oil Temperature / Temperature Sensor
Posted by PerDiezel Solutions on
Fault Condition: The Electronic Malfunction Lamp (EML) will turn on and PID 175 will set if the engine oil temperature signal voltage is less than .17 volts or greater than 4.92 volts. If the EMS Module senses that the engine oil temperature signal is critically above range, FMI code 0 will be set. If the engine oil temperature reaches 259°F (126°C), the engine power will be reduced by 15%. If the engine oil temperature reaches 262°F (128°C), the engine will be shutdown. Yellow or red warning lamp identification and buzzer warning will accompany the extreme engine oil temperature conditions. If...
