Nox sensor specifications. NOx Sensor The NOx sensor is a stand-alone multifunction sensor, which can be operated, for example, with the ALL-IN-ONE. #Exhaust-gas treatment #Diagnostics #NOx #Nitrogen oxide #Ammonia NO X sensor Diagnosis and monitoring of nitrogen oxides and ammonia in the exhaust system Very precise and real-time readings from the exhaust gas system are required for efficient exhaust-gas treatment. Our Nitrous Oxide Sensors are fabricated using the same genuine VDO components, control chips, circuit boards, and wire harnesses. The actual page dedicated to knock sensor only tells me about code for the knock sensor and how to diagnose it, nothing regarding torque specs. These sensors create a voltage signal based on the vibrations caused by erratic air/fuel mixture combustion; the engine control module uses these signals to adjust the ignition timing and air/fuel mixture This technical data sheet provides specifications for a NOX sensor with part number 56. This technical data sheet provides specifications for a NOX sensor with part number 56. Standardized electronics interface via CAN bus . I did get a knock retard on my engine. Symptoms of a bad knock sensor include a check engine light, loud thumping noises coming from the engine, or shaking, vibrating, and misfires on a cold start.
