Repair codes: P1684 and P0135 What do these codes mean? Any help available?


P1684 means battery was disconnected in the last 50 starts. This could be true if you replaced the battery. If not then you need to check all the cables.
P0135 means an oxygen sensor needs replaced because it is having trouble reaching the correct temperature. There are heaters in them and they fail just like a lightbulb.

I have a dodge grand caravan wit the code p0135. internal controlmodule memorie check sum error no clue as to what it means please help


Code 135 should be a problem with the heater circuit for O2 sensor bank one sensor one. The O2 sensors have a heater to make them work as soon as the engine is started. The problem could be the sensor or the heater circuit.

rule of thumb on any vehicle. always use the factory sensors for anything. they just are made for your vehicles computer. hint...buy them online and shop around for best price.
