Hi friend ,maybe this PDF can help you to solve the problem, Diagnostic Trouble Code Table ,hope can help you .And you can use ELM327 .
The problems are at cylinder misfire detected, you should go to do some fix~~~

Pull out your spark plugs. Change them if dirty. There might be a problem with the fuel trim, thats causing spark plug to foul up prematurely. A stucked open EGR valve can also cause a multiple mispfire code(P0300) but then it would be accompanied by an EGR code(P402) which means excessive flow detected. Anyways if was indeed a fouled up spark plug change them as well as the air filter.

Basically this means that the the car's computer has
detected that not all
of the engine's cylinders are firing properly.
A P0300 diagnostic code indicates a random or multiple misfire. If
the last digit
is a number other than zero, it corresponds to the cylinder number
that is misfiring.
A P0302 code, for example, would tell you cylinder number two is
misfiring.
Unfortunately, a P0300 doesn't tell you specifically which cylinder(s)
is/are
mis-firing, nor why.
Symptoms may include:
A code P0300 may mean that one or more of the following has happened:
Possible Solutions
If there are no symptoms, the simplest thing to do is to reset the
code and
see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating,
check
all wiring and connectors that lead to the cylinders (i.e. spark
plugs). Depending
on how long the ignition components have been in the car, it may be a
good
idea to replace them as part of your regular maintenance schedule. I
would
suggest spark plugs, spark plug wires, distributor cap, and
rotor (if applicable).
Otherwise, check the coils (a.k.a. coil packs). In some cases, the
catalytic
converter has gone bad. If you smell rotten eggs in the exhaust, your
cat converter
needs to be replaced. I've also heard in other cases the problems were
faulty
fuel injectors.
Random misfires that jump around from one cylinder to another (read:
P030x
codes) also will set a P0300 code. The underlying cause is often
a lean fuel
condition,
which may be due to a vacuum leak in the intake manifold or unmetered
air getting
past the airflow sensor, or an EGR valve that is stuck open.

SOURCE: code p0300 and p1406
P0300 is misfire and p1406 is EGR. It sounds like you have a chunk of carbon stuck in the EGR valve. Remove the valve and clean the carbon from the valve, bottom side. Then install a screened gasket so it won't happen again.

change the crank sensor and do a crank relearn with a dignostic scaner.

P2135 Throttle Position Sensor (TPS) Property Malfunction, remember this is not a car that is built by GM it is a Korean import.
From www.hondasuv.com:
The P1399 random misfire along with one or more of these codes: P0301, P0302, P0303, P0304 -- indicates a problem with the valves. The B20 engines in the 1997-2001 CR-Vs are known to have problems with valves tightening and then 'burning'.
So the first question is when was the last time you adjusted the valves? If you don't know or never have, then have them adjusted. Soon...
