check if it's loaded with the kernel
Code:
lsmod | grep i2c

You may need to install lmsensors

once installed, invoke the install script as root, with
Code:
sensors-detect
and you should have i2c module installed.

Hi and had installed the lm sensor but when i tried to sudo sensors-detect , /sys/bus/pci/devices: No such file or directory at /usr/sbin/sensors-detect line 2900 was shown anyone know how I can fix this problem?

OK, to get i2c to load with system start, add the module name to the list in,

/etc/modprobe.preload

Code:
# /etc/modprobe.preload: kernel modules to load at boot time.
#
# This file should contain the names of kernel modules that are
# to be loaded at boot time, one per line.  Comments begin with
# a `#', and everything on the line after them are ignored.
# this file is for module-init-tools (kernel 2.5 and above) ONLY
# for old kernel use /etc/modules
