You need to determine if it's the horn or the alarm. My Montero (not Sport) had 3 horns. All 3 of which go off w/ the Alarm, but only one is connected to the horn on the steering wheel. I could not make mine go off w/o pulling the relay under the hood.

My spring was bad in the steering wheel. I was able to bypass the wire using instructions that I actually found on a Mitsubishi Forum. Link below:

The tire size depends on the vehicle trim level. Below are multiple trim levels and their respective tire sizes.

ES 235/75/15
LS 255/70/16
Limited 255/70/16
XLS 255/70/16
XS 255/70/16

The best thing to do if the vehicle is available is to inspect the tire sidewall for what the current equipment is. There is also typically a sticker in the driver door jamb, center console or glovebox stating the proper tire size & inflation.

P0156 code means :Oxygen Sensor Circuit No Activity Detected (Bank2, sensor1) I'm not sure but i think it's on the exhaust manifold!!!

you can find your engine serial nos. on the lower mid part of your engine block, its embossed in there

Replace the oxygen sensor. Left side, before cat converter.

bank 1 refers to your driver's side and bank 2 refers to your passanger side. sensor 1 is pre cat and sensor 2 is post cat. Your vehicle has a v-6 so bank 1 sensor 1 is on the drivers side before the catalytic converter. It will be on your exhaust pipe between your exhaust manifold and your catalytic converter.
