ENGINE DATA LIST

The Engine Data List menu selection displays the set of DDEC III/IV data that pertain to the operation of the engine and

vehicle.

NOTES:

(1) Engine data list values that are displayed as `N/A' (not available) typically indicate that the sensor(s) and/or function is not

part of the engine configuration, or the data is not being transmitted by the DDEC III/IV ECM. These are not included in the

following lists.

(2) Engine sensor values that are displayed as `FAIL' is an indication that a FMI 3 (Sensor Voltage High) or a FMI 4 (Sensor

Voltage Low) diagnostic condition is currently active for that sensor(s).

ACTIVE CODES

Definition: Indicates the presence of a condition(s) that causes the check engine light to be on.

Typical Range: YES or NO

INACTIVE CODES

Definition: Indication that past active codes have been stored in the ECM memory.

Typical Range: YES or NO

ENGINE RPM

Definition: Indicates engine RPM as determined by the Timing Reference Sensor (TRS).

Typical Range: 0 to 2500 RPM

PULSEWIDTH

Definition: Fuel Pulse Width -- Number of degrees crankshaft rotation that the EUI's control valve is closed and fuel is

entering the cylinder

Typical Range: 0.0 to 25.5 Degrees

BOOST PSI

Definition: Boost Pressure -- Pressure of air measured by the Turbo Boost Sensor (TBS) downstream on the

compressor discharge side of the turbocharger.

Typical Range: (0.0 to 43.5 PSI) or (0 to 305 KPa)

ENG LOAD PCT

Definition: Indicates the percent engine load calculated from engine speed and torque.

Typical Range: 0 to 100%

TORQUE LB-FT or NM

Definition: Indicates the amount of torque available at the engine flywheel. Negative torque values will be displayed

with a minus sign in front of the value.

Typical Range: --9999 to 9999 LB-FT / --9999 to 9999 NM

TPS CNTS

Definition: Throttle Position Sensor (TPS) Counts (CNTS). Indicates the analog to digital (A/D) conversion of (0 to 5

volts) from the TPS to (0 to 1024 counts) that the ECM uses to compute the percent throttle opening.

Typical Range: (0 to 1024 Counts) or N/A

TPS PCT

Definition: Indicates the percent opening of the Throttle Position Sensor (TPS).

Typical Range: 0 to 100%
