there is no way of knowing unless you have your vehicle scan for trouble codes.anything we tell you will be nothing more than a guess. You can go to Advance Auto or Auto Zone and they will scan it for free and tell you the code and what the code means.
Headlights might stay on in a Honda Odyssey after the engine is turned off because of a courtesy timer. The headlights will stay on for a few seconds after exiting the vehicle so the driver can go into a building at night safely. If the headlights are staying on all the time, check the timer for this feature.
You first have to have it checked for codes. You then repair the cause of the code. Finally you clear the code witha scan tool.
yes
Yes, and the check engine light should illuminate.
Likely your transmission is dying. Google "odyssey transmission" and you will find lots of reports about problems with 2000- 2004 Odyssey transmissions. If you are persistent enough, Honda might help some with the repair.
Not likely but it will wear the tires out.
No, but it could cause the check engine light to illuminate.
It is possible, anything that could affect the emissions of the vehicle can turn the check engine light on.
Not likely. A bad O2 sensor would illuminate the check engine light and the engine performance would suffer.
It indicates transmissions problems. Had this happen at 103,000 km on our 2002 Honday Odyssey and had to replace the entire transmission.
Yes it could but, it should also illuminate the check engine light.
A bulb would cause it to illuminate!!
