Hi I have a 2004 Dodge Caravan with a 3.3 liter engine and it shows a fault code # P0137. Could you please tell me what this code means. Hope you can help!!!!!

One of the wires to an oxygen sensor on your exhaust manifold has a break in the insulation and it is shorting against part of the metal frame of the vehicle. The oxygen sensors look a bit like spark plugs set into the side of the exhaust manifold. I think I am right in saying that on the V6 dodges there are 4 such sensors One on each exhaust manifold before the catalytic converters and one after each catalytic converter. Check them all but I think the code is for the second sensor (after the catalyst) on bank one (the bank of cylinders closest to the radiator). The cable attached to each oxygen sensor has four wires within it, two to power the sensor heater (the need to be warm to work) and two for the oxygen sensor element.
