Engine 2 Data

Engine Speed - Range 0-16384 RPM: From the fuel control reference input, the PCM computes the Engine Speed. The engine speed should remain close to the desired idle under the various engine loads with the engine idling.

Desired Idle Speed - Range 0-3187 RPM: The PCM commands the idle speed. The PCM compensates for the various engine loads in order to keep the engine at the desired idle speed.

ECT - Range -4O°C to 215°C (-4O°F to 419°F): The Engine Coolant Temperature (ECT) sensor sends the engine temperature information to the PCM. The PCM supplies 5 volts to the engine coolant temperature sensor circuit. The sensor is a thermistor which changes the internal resistance as the temperature changes. When the sensor is cold meaning the internal resistance is high, the PCM monitors a high voltage which the PCM interprets as a cold engine. As the sensor warms meaning the internal resistance decreases, the voltage signal decreases. The PCM interprets the lower voltage as a warm engine.

IAT - Range -4O°C to 215°C (-4O°F to 419°F): The PCM converts the resistance of the Intake Air Temperature (IAT) sensor to degrees in the same manner as the ECT sensor. The PCM uses the intake air temperature in order to adjust the fuel delivery and the spark timing according to the incoming air density.

MAP - Range 11-105 kPa, 0-5.0 Volts: The Manifold Absolute Pressure (MAP) sensor measures the change in the intake manifold pressure which results from the engine load changes and the engine speed changes. As the intake manifold pressure increases, the air density in the intake also increases.

BARO - Range 11-105 kPa: The Barometric Pressure (BARO) sensor measures the change in the intake manifold pressure which results from the altitude changes. This value is updated when the ignition is turned ON and at a Wide Open Throttle (WOT).

TP Sensor - Range 0-5.0 Volts: The PCM uses the Throttle Position (TP) sensor in order to determine the amount of the throttle demanded by the vehicle's operator. The TP sensor reads between 0.36-0.96 volt at idle to above 4 volts at Wide Open Throttle (WOT).

TP Angle - Range 0-100 %: From the TP sensor voltage input, the PCM computes the Throttle Position. The TP angle will auto zero to 0% at idle (TP voltage below 0.90 volt). The TP angle will read 100% at Wide Open Throttle.

Total Misfire Current Counter - Range 0-255 Counts: Indicates the total number of misfires that have been detected in all the cylinders after the 100 engine cycles. One cycle equals one complete 4 stroke cycle. The total misfire only increments during the steady state cruise conditions.

Air Fuel Ratio - Range 0:1-25.5:1: The Air Fuel Ratio indicates the air to fuel ratio based on the Oxygen Sensor (O2S 1) inputs. The PCM uses the fuel trims to adjust fueling in order to attempt to maintain an air fuel ratio of 14.7:1.

Base Pulse Width Modulation (PWM) Cyl. 1 - Range 0-999.9 mS: The base PWM Cyl. 1 indicates the base Pulse Width Modulation (PWM) or the ON time of the cylinder 1 injector in milliseconds. When the engine load increases, the injector pulse width increases.

Base PWM Cyl. 2 - Range 0-999.9 mS: The base PWM Cyl. 2 indicates the base Pulse Width Modulation (PWM) or the ON time of the cylinder 2 injector in milliseconds. When the engine load increases, the injector pulse width increases.

Base PWM Cyl. 3 - Range 0-999.9 mS: The base PWM Cyl. 3 indicates the base Pulse Width Modulation (PWM) or the ON time of the cylinder 3 injector in milliseconds. When the engine load increases, the injector pulse width increases.

Base PWM Cyl. 4 - Range 0-999.9 mS: The base PWM Cyl. 4 indicates the base Pulse Width Modulation (PWM) or the ON time of the cylinder 4 injector in milliseconds. When the engine load increases, the injector pulse width increases.

A/C Request - Range Yes/No: The A/C Request Represents whether the HVAC selector is requesting the Air Conditioning (A/C) system. The PCM receives the input. Finally the scan tool receives the input over the class 2 serial data.

A/C High Side Pressure - Range 0.0-5.0 Volts, 0.0-3165 kPa: The A/C.High Side displays the pressure value of the A/C refrigerant pressure sensor. The A/C High Side helps diagnose the DTC P0530.

A/C Relay - Range Off/On: The A/C Relay represents the commanded state of the A/C clutch control relay. The A/C clutch should be engaged when the scan tool displays ON.

Stepper Cruise Motor- Range Disable/Enabled: The Stepper Cruise display indicates if the PCM is allowing the cruise operation. The PCM has the ability to disable the cruise control under certain conditions.

Cruise - Range Yes/No: The cruise engaged is an input from the cruise control module to the PCM. The cruise engaged indicates if the cruise control is in control of the vehicle. The PCM uses this information to change the transmission shift calibrations and to turn ON an indicator lamp on the Instrument Panel Cluster (IPC). The cruise engaged helps diagnose the Cruise Control Diagnosis.

TR Switch - P, A, B, C - Scan Tool Displays High or Low: The TR switch P, A, B, C display represents the states of the four inputs from the Transaxle Range Pressure Switch Assembly. "High" indicates a B+ voltage signal being monitored at the PCM, "Low" indicates a grounded input signal. The combination of Transaxle range inputs indicates the position of the Transaxle manual valve.

Transmission Range - Range Valid/Invalid: Trans Range represents the decoded status of the four inputs from the Transaxle Range Switch Assembly. The combination of Transaxle range inputs the position of the Transaxle manual valve.

Vehicle Speed km/h - 0-255 MPH, 0-255 km/h: The PCM converts the vehicle speed sensor into MPH (km/h) for the display. From the PCM, the vehicle speed output is 4000 pulses per mile. The scan tool uses the class 2 serial data from the PCM in order to obtain the vehicle speed. The instrument panel cluster, the cruise control module, and the multi-function alarm module use the 4000 ppm output.

Output Driver 1 - Range SHRT00000000 Open00000000 (binary display): The PCM uses the Output Driver Modules in order to allow the various systems to function by providing a ground circuit. The scan tool displays Os in each of the 8 positions when the circuitry is OK. If a 1 appears in any of the positions, then PCM detects either a short circuit or an open circuit. Refer to PCM Outputs Diagnosis.

Output Driver 2 - Range SHRT00000000 Open00000000 (binary display): The PCM uses the Output Driver Modules in order to allow the various systems to function by providing a ground circuit. The scan tool displays Os in each of the B positions when the circuitry is OK. If a 1 appears in any of the positions, then PCM detects either a short circuit or an open circuit. Refer to PCM Outputs Diagnosis.

Engine Run Time - Range 0:00:00-18:12:15 hours:minutes:seconds: The engine run time is a measure of how long the engine has been running. When the engine stops running, the timer resets to zero.

# of Curr. DTCs - Range 0-255: The # of Curr. DTCs indicates the total number of current Diagnostic Trouble Codes (DTCs) set. These current DTCs set does not necessarily mean that the Malfunction Indicator Lamp (MIL) is illuminated.
