My horn on my pt crusier is stating on. right now i have the battery dis-connected,what should i do?

The most optimum pressure in all four is 32-34 PSI

I do not have any info for this code.po68a,Are you sure that its right! check the plugs and fuel filter for the bogging issue. Repost if needed. God-Bless!

make sure the battery is charging, make sure the alternator is putting out correct amp/volts, check cable connections of battery - at both ends, check connections of harness at back side of fuse boxes, check harness connection block at firewall (both sides of firewall)
, check harness connections leading up into underside of dash.
Ensure all ground connections are tight and not broken.

You will need multimeter and probe tool with light.

you should push on your horn switch and if it makes a click sound then it usually means you need a whole new horn. it wouldnt help to get a wiring diagram and test some wires to see if you have power and ground going to your relay and horn.

It could be an ignition switch, ignition coil, starter, (most likely) or starter solonoid.

Check for a faulty oil pressure sending unit on engine block. Also check for a bad connection between the oil pressure sending unit and the wireing. Hope this will help.

The first code, p1684, just states the battery has been dis-connected in the last 50 start cycles.
Code p0401 is the EGR flow. You may need to replace the EGR valve.
Code p1193 is the intake air temperauture ( IAT) sensor. It may also need to be replaced.
Have your mechanic take a look at those, and please let me know how it goes.

find the horn ,it should be at the front possibly behind the bumper ,run a wire direct to it and see it works ,if it does work then its the wiring in the steering wheel ,but as this vehicle no doubt has an air bag then entrust this job to a garage because if you get it wrong the air bag will explode ,expensive job to say the least

Horn is located on the right side frame rail. pull the inner fender and you will see it.
