For 1990-2009 cars
Actual Fuel Level: The scan tool displays 0-33.68 gallons. The IPC calculates the amount of fuel remaining in the tank based on the input from the fuel level sensor.
Battery Voltage: The scan tool displays 0-25.5 volts. The voltage measured from the IPC's battery positive voltage circuit to the IPC's ground circuit.
Coolant Temp: The scan tool displays -40°C (-40°F) to 140°C (284°F). The state of the engine coolant temperature detected by the IPC.
Coolant Temp Sensor: The scan tool displays 0-10 volts. The state of the voltage at the coolant temp sensor detected by the IPC.
Coolant Warning Lamp: The scan tool displays On/Off. The state of the engine coolant temperature indicator as commanded by the IPC.
Engine Speed: The scan tool displays 0-8000 RPM. The IPC is responsible for calculating correct engine speed data.
Fuel Level Gauge: The scan tool displays 0-33.68 gallons. The IPC calculates the amount of fuel remaining in the tank based on the input from the fuel level sensor.
Fuel Level Gauge: The scan tool displays 0-10 volts. The IPC calculates the amount of fuel remaining in the tank based on the input from the fuel level sensor.
Key In Ignition: The scan tool displays Yes/No. When the key is in the ignition switch (signal circuit low), the scan tool will display Yes. When the key is out of the ignition switch (signal circuit high), the scan tool displays No.
Low Fuel Lamp: The scan tool displays On/Off. The state of the low fuel indicator as commanded by the IPC.
Switched Battery Voltage: The scan tool displays 0-25.5 volts. The voltage measured from the IPC's switched battery positive voltage circuit to the IPC's ground circuit.
Vehicle Speed: The scan tool displays 0-255 km/h. The IPC monitors the voltage at the signal circuit of the EBTCM. The voltage is proportional to the vehicle speed.
Vehicle Speed (Units): The scan tool displays km/h or mph.
