Jetta A4 oxygen sensor

Teno a jetta at 4 and the oxygen sonsor that goes in the catalyst is not

connected

Colega:
If the vehicle has the oxygen sensor incorporated, it may be sure that it carries it, also if it is not connected, the motor yield decreases, since the signal of the value of the quality of the quality of the mixture will not analyze it for not having how to do it and therefore this influences the establishment of the optimal mixture for any of the working conditions of the engine; The connector must be located near the sensor, if it is not, I recommend going to a spell workshop to repair it. Now if what you have seen is the wiring or harness connector and there is no sensor to connect it, do not worry, the factory wiring systems are designed many times standardized, which may or may not include certain elements, depending on the so -called optional, this can be a case.

The best way is to follow the cable branch to see where I remain, on the occasion they disconnect and roll up the cable above

The sensor connector must be in the range range of the cable, the scanner is marking?, The mixture is varied if it is disconnected, greetings
