Oil Temperature Sensor: This parameter displays the engine oil temperature in degrees C. Power Enrichment: This parameter displays the status of the operating mode of the ECM used to increase fuel delivery Reduced Engine Power: This parameter displays when the ECM is commanding reduced engine power due to a Requested Torque: This parameter displays the calculated amount torque requested of the ECM by the Transmission Short Term Fuel Trim (Bank 1 or Bank 2): This parameter displays the short-term correction to the fuel delivery by the Spark Advance: This parameter displays the amount of spark advance the ECM is commanding on the ignition control Starter Relay: This parameter displays the Em’s commanded state of the starter motor relay control circuit. Starter Relay Circuit Status: This parameter displays the state of the starter relay control circuit. The parameter Start Up ECT (Engine Coolant Temperature): This parameter displays the temperature of the engine coolant on start Start Up IAT (Intake Air Temperature): This parameter displays the temperature of the intake air at start in the air Time Since Engine Off: This parameter displays the amount of time (hours:minutes:seconds) that has elapsed since Total Fuel Trim (Bank 1 or Bank 2): This parameter displays the overall fuel trim from the idle/decel cell and the Total Misfire: This parameter displays the total number of cylinder firing events that the control module detected as TP Sensor 1 (Throttle Position): This parameter displays the actual voltage on the TP sensor 1 signal circuit as TP Sensor 1 Learned Lower Position (Throttle Position): This parameter displays the learned minimum value of TP TP Sensor 2 (Throttle Position): This parameter displays the actual voltage on the TP sensor 2 signal circuit as TP Sensor 2 Learned Lower Position (Throttle Position): This parameter displays the learned minimum value of TP TP Sensor 1-2 Correlation (Throttle Position): This parameter displays ‘Fault’ when the ECM detects that TP sensor 1 Transmission Gear: This parameter displays the position of the transmission gear selector that is transmitted over the Transmission Gear Selector Signal: This parameter displays the position of the transmission gear selector that is Vehicle Speed: This parameter displays the speed of the vehicle as calculated by the TCM from information received Volumetric Efficiency: This parameter displays the volumetric efficiency of the engine as calculated by the control 8.5 OBD Data Typical Values Tech 2 Display Units Displayed Ignition On Engine Running B1S1 O2 Sensor (Bank 1 Sensor 1) mA 0.008 0 |
