DEFINITION VALUE VALUE DESCRIPTION
Engine Runtime
Since Key On
Time the engine has
been running since
the key was last
cycled on
0 minutes to ∞
—
Engine Runtime Total
Total amount of
engine run time
0 minutes to ∞
—
Engine Temperature
Coolant temperature
at the ECT sensor
70° F (21° C) Room temperature
195° to 210° F (92°
to 99° C)
Cooling fan running
≈ 232° F (111° C) Hot light on – power limit
≈ 237° F (114° C) Engine protection (ignition misfire)
≈ 252° F (122° C) Engine protection (shutdown)
Fuel Pump
ECU control of the
fuel pump
On
ECU is grounding the fuel pump relay. ECU
ground this relay for the first 2–3 seconds after
key on and any time RPM is seen from the CPS
Off
ECU is not grounding the fuel pump relay. Pump
not running
Ignition Coil Dwell
Time the ECU is
grounding the coil
≈ 2–3 ms
–
Ignition Timing
Degrees BTDC that
the ECU is signaling
the coil to send spark
to a cylinder
0 to 10° BTDC
Typical ignition timing on a warm engine at idle
30 to 40° BTDC
Typical max spark at wide open throttle
Injector Pulse Width
Time the ECU is
grounding the
injectors
2–3 ms
Average reading on a warm engine at idle
4–7 ms
Unit is start-up enrichment or under rapid
acceleration
Intake Air
Temperature
Measures air
temperature at the
TMAP sensor
varies
should be close to ambient air temperature.
Warm engine at idle may cause reading to be
higher
Intercooler Pump
Driver
Indicates if the
electric fuel pump is
being triggered on by
the ECU
Inactive
ECU is not triggering the pump to run. Seen
when key is ON but engine is not running
Active
Vehicle is running and pump is active
Manifold Absolute
Pressure
Measures air
pressure inside the
intake manifold on
the TMAP sensor.
Reading will be high
at key on and wide
open throttle.
Reading will be low
at idle / closed
throttle.
14.7 PSI (101 kPa) Engine not running and unit is near sea level
5–7 PSI (34–48
kPa)
Normal reading when warm engine is at idle
7–11 PSI (48–76
kPa)
Normal reading when unit is 1/2 throttle to WOT.
value will be higher on a turbocharged unit
Percent Engine Load
How much load the
engine is under
20–30%
Typical warm idle. Cold start up reading will be
higher
RPM Limit
Indicates if the ECU
is currently limiting
RPM
Active
ECU is limiting the RPM
Inactive
ECU is not limiting RPM
Selected Gear
Indicates what gear
position the
transmission switch
is in
dependent on gear
selected
High, Low, Neutral, Reverse, Park
”–” or Null indicates no reading from the sensor /
stuck between gear positions
