Thank you and I was afraid of that. Below from the engine operator manual ...all is normal until about 3 seconds after it does it's system check. Question: is it worth to buy an engine scan tool?
The non-emissions-related indicator light is a red
colored encircled triangle and exclamation mark
icon. When lit, it indicates that an engine-monitored
malfunction has been detected.
When the ignition switch is turned to RUN (key on,
engine off), the emissions-related indicator will light
up and stay lit until the engine is started. When the
ignition switch is turned to RUN (key on, engine off),
the non-emissions-related indicator will light up for 5
An audible alarm will perform a brief self-test when
the ignition key is turned to the RUN position. The
alarm emits three short beeps to indicate that the
ECM is performing a check of the sensors. If there
are any problems detected by the ECM, the alarm
will sound; otherwise, it will remain off.
Whenever either icon lights up, it will be accompanied
by a brief, single beep from the audible alarm to
indicate that there is a malfunction.
