Engine Coolant Light (On / Off)
When the ECM detects a low coolant level it will indicate an ON condition.
Normal operating mode is OFF.
Engine Hot Light (On / Off)
A detection of an engine hot condition will show ON. Normal operating
mode is OFF
Engine Load
Range: 0 to 255
This replaces the MAP sensor on some engines. Indicates the grams of
air displaced per cylinder that is used to calculate spark and fuel settings.
Engine RPM
Engine speed displayed in revolutions per minute.
Engine Run Time (Seconds)
The elapsed time that the engine has currently been running, displayed
in seconds.
EGR (On / Off)
If the output vacuum EGR solenoid is being commanded to energize by
the ECM, the screen should read ON. If the ECM is not commanding the
solenoid, the screen should read OFF.
EGR Duty Cycle (% On)
Range: 0 to 100%
The amount of time that the solenoid in the exhaust gas re-circulation
valve has been cycled ON. The solenoid is cycled to quickly modulate the
valve and control its air flow.
EGR Position (% Open)
Range: 0 to 100%
Vehicles that are equipped with an EGR position sensor can report pintle
position of the EGR valve so that the ECM can verify that the EGR
vacuum solenoid is properly modulating the EGR for desired position.
EGR Solenoid 1,2 or 3 (On / Off)
The solenoid in the exhaust gas re-circulating valve allows exhaust
gasses to pass. Some engines control the gas flow with three solenoids.
ESC Severe Knock (On / Off)
Electronic Spark Control monitors ignition performance. If the ECM
detects a high frequency of knock it will indicate ON. Normal operation is
OFF.
EST (Enabled / Disabled)
