What is meaning of p1492code it is obd code

wow, no car maker stated, no year, (96'+?) and no car model.
and no engine stated, so all answers will be wild guessing. (MINE TOO)! no country stated either.....
meaning now that opens an endless book, huh
3 years off ASE training ,all typed here? 50 years experience. .
here are some small hints.
this is called OBD2 monitors.
and monitor runs full time key on and more running. (like a nanny)
it sees errors and reports them, .
the ASE Tech looks them up in the FSM for this exact car, not others
and finds out what the test does, and why it fails. (test specs)
those are the basic ROPE'S. (and reset it and see if it comes back)
p1 is a factory code not unversal federal P0 codes....
so only the correct book works. is best ,IMO.

using google we see the warnings, do not guess at maker names.
and shows, not to guess what it means, P1 means that.
P1492 JEEP
P1492 SUBARU by no means a complete list.

Engine light flashing on 2001 Wrangler Jeep,know to take to dealer, any easy causes?

You need to run diagnostics as any shop would. Most larger parts stores will do a quick code scan and give you codes. Get a manual and track down systems that are indicated and do individual component testing with a digital multimeter. This is not foolproof but is far better than buying lots of expensive parts and not solving the problem!!
Impossible to give you a definite cause as the light will flash when any number of systems need attention!
