The BlueDriver Bluetooth Pro OBDII scan tool provides access to a wide range of live data parameters, allowing users to monitor vehicle performance and diagnose potential issues. This comprehensive guide details the standard OBDII live data accessible with BlueDriver, categorized for easy navigation. Note that specific datapoint availability varies depending on the vehicle’s year, make, and model. Use the BlueDriver Compatibility Tool to confirm supported datapoints for your vehicle.
Vehicle Operation Data with BlueDriver
Monitoring vehicle operation data provides insights into engine performance and driving conditions. BlueDriver can access crucial parameters such as:
-
Engine RPM: Measures engine speed in revolutions per minute.
-
Vehicle Speed: Displays current vehicle speed.
-
Engine Coolant Temperature: Monitors coolant temperature, often measured at the cylinder head or before the radiator. Some vehicles may report a second sensor (ECT 2) with varying locations. Consult your vehicle’s factory manual for sensor specifics.
-
Engine Oil Temperature: Tracks engine oil temperature, with sensor location varying by vehicle.
-
Ambient Air Temperature: Measures the surrounding air temperature, usually a few degrees lower than intake temperature.
-
Barometric Pressure: Displays local atmospheric pressure as an absolute value, influenced by altitude and weather conditions.
-
Accelerator Pedal Position: Reports the position of the accelerator pedal. Up to three sensors (D, E, F) may be present.
-
Relative Accelerator Pedal Position: Shows accelerator pedal position adjusted for learned vehicle behavior.
-
Commanded Throttle Actuator: Displays the throttle position requested by the Engine Control Module (ECM) based on accelerator pedal position.
-
Relative Throttle Position: Indicates throttle position relative to the learned closed position, compensating for changes due to carbon buildup.
-
Absolute Throttle Position: Shows how open the throttle is (0% fully closed, 100% fully open). Up to four sensors (TPS A/1, TPS B/2, TPS C/3, TPS D/4) may exist.
-
Control Module Voltage: Displays the input voltage at the ECM, reflecting battery voltage when the engine is off and alternator voltage when running.
-
Hybrid Battery Pack Remaining Life (State of Charge): Shows the remaining charge in the hybrid battery pack as a percentage.
-
Hybrid/EV Vehicle System Status: Reports charging state (Charge Sustaining Mode or Charge Depletion Mode), battery voltage, and battery current.
-
Calculated Engine Load Value: Represents the current engine load as a percentage of maximum available torque.
-
Absolute Load Value: Represents air mass intake per stroke as a percentage, normalized to standard temperature and pressure.
-
Driver’s Demand Engine – Percent Torque: Shows the percentage of maximum torque requested by the ECM based on accelerator pedal, cruise control, and transmission inputs.
-
Actual Engine – Percent Torque (Indicated Torque): Displays the current percentage of total available torque, including net brake torque and friction torque.
-
Engine Friction – Percent Torque: Indicates the percentage of torque required to run the engine at no load, including internal components and accessories.
-
Engine Reference Torque: Represents the engine’s torque rating, used as the 100% value for torque-related parameters.
-
Engine Percent Torque Data: Provides up to five different maximum torque ratings, reflecting changes due to varying vehicle/environmental conditions.
-
Auxiliary Input/Output: A composite datapoint reporting Power Take Off status, transmission status, glow plug lamp status, and recommended gear (if supported).
-
Exhaust Gas Temperature (EGT): Reports exhaust gas temperature from various sensor locations (post-turbo, post-cat, post-DPF). Consult your vehicle’s manual for specific sensor locations.
-
Engine Exhaust Flow Rate: Measures exhaust flow rate in kg/hr or lbs/hr upstream of the aftertreatment system.
-
Exhaust Pressure: Displays exhaust pressure as an absolute value. Sensor location may vary, refer to your factory manual.
-
Manifold Surface Temperature: Measures the temperature at the outer surface of the exhaust manifold.
-
Timing Advance for #1 Cylinder: Indicates the crankshaft angle (in degrees BTDC) at which the spark plug for cylinder #1 fires.
-
Engine Run Time: Reports total engine run time, idle time, and PTO engaged time.
-
Run Time Since Engine Start: Shows run time in seconds since the last engine start.
-
Time Run with MIL On: Displays engine run time since the check engine light (MIL) was activated.
-
Distance Traveled while MIL is Activated: Shows the distance driven since the MIL was last illuminated.
-
Time since Trouble Codes Cleared: Indicates engine run time since diagnostic trouble codes were last cleared.
-
Distance Traveled Since Codes Cleared: Shows the distance traveled since codes were last cleared.
-
Warm-ups Since Codes Cleared: Counts the number of engine warm-up cycles since codes were last cleared.
Fuel & Air Data Insights with BlueDriver
BlueDriver provides access to critical fuel and air data, enabling analysis of fuel system performance and efficiency:
-
Fuel System Status: Indicates whether the engine is operating in open or closed loop mode.
-
Oxygen Sensor Voltage: Displays the voltage signal from the oxygen sensor.
-
Oxygen Sensor Equivalence Ratio (Lambda): Represents the fuel-air ratio as a lambda value.
-
Oxygen Sensor Current: Indicates air-fuel mixture richness or leanness based on current flow.
-
Short Term Fuel Trim: Shows rapid fuel injection adjustments based on oxygen sensor data.
