Hi Palomoynaty, if you are taking air in the catalyst/collector line, the probe will continue to fail, also if the plug or wiring of this, this defective fails, then also that there are no false inputs of air in the admission (joints collectors), if reviewing this, the fault is not corrected, nor disconnecting the battery by 15 min, some throw "by the path of the path" He says ... manipulate the painting and deconed the checkfish of the check ... but this is not honored, nor typical of a mechanic, but if there is no more "wool" to spend, nor more means this is already choice of each. Greetings!!
