2 problems with 01 Rodeo P0430 code & water leak

[angela5503]

P0430 code went away for 2 weeks then came back. I cleaned the EGR but apparently that wasn't the problem. 02 sensor next? Also,theres water dripping from a small hose coming out of the firewall on passengers side.

It's not surprising that cleaning the EGR didn't fix a catalytic converter or O2 sensor problem. You can either replace the O2 sensor or if you're not sure whether or not your cat is bad, swap the after-cat sensors and see if the code "follows" the questionable sensor.

If the water is dripping out of a hose in the engine bay, it's normal, I think. From the A/C... Help me out if I'm wrong.

Agree with both points.

Swap the o2 sensors and see if it follows.

The water is condensate from the a/c system. I usually recommend turning off the a/c about a mile from where you are going to stop but leave the fan on high and air selector on fresh. Helps dry out the coil and keeps nastyness from growing in the evaporator section and causing the 'dirty sock' smell.
