Question about 2003 Dodge Grand Caravan AWD
Code reads 0134-could you please tell me what that is.
P0134 O2 Sensor Circuit No Activity
Detected (Bank 1 Sensor 1)
This means that the primary (pre-catalytic converter) oxygen sensor in cylinder bank number 1 is defective. Bank one is the one with cylinder one in it (not sure offhand which that is, but check your spark plug wires and see if they're numbered, or if there is numbering on the distributor cap - if there is, follow the wire labeled as number 1 to see which side of the engine it goes to). That's the side the defective sensor is on, and it'll be the one on that side that is before the catalytic converter. Its responsibility is to tell the ECU what the air/fuel mixture is in the exhaust on that bank of cylinders, so that the fuel mixture can be trimmed correctly. When it fails, you usually see diminished gas mileage, maybe some black smoke out the back of the van, and possibly a little roughness in the idle.

Arrows pointing down is low coolant. If you
can't read the code because it displays, "communication error", you
have a blown fuse. Your ALDL may be tied in with the auxiliary plug. Look for a
blown fuse and replace it.
