Sensor Reference Voltage A Circuit Low at Roy Chowdhury blog

Sensor Reference Voltage A Circuit Low. Look for any damage or corrosion. Causes range from faulty ecm, damaged wiring, to poor ground connections. the p0642 diagnostic trouble code refers to a potential issue with the sensor reference voltage 'a' circuit being. This trouble code signals a low sensor reference voltage “a” circuit. Check the engine control module (ecm) for faults and ensure the circuit connections are secure. diagnostic trouble code (dtc) p0642 stands for “sensor reference voltage ‘a’ circuit low.” it means the powertrain control module (pcm) identifies an inaccurate output signal or a voltage signal that’s lower than a programmed limit from the engine sensors. p0642 is a code that indicates the signal from the reference voltage circuit “a” detected by the powertrain controller module (pcm), or related control modules,. Symptoms include the check engine light, reduced engine performance, and poor fuel economy. to fix the p0642 fault code, start by visually inspecting the wiring harness and connectors. Control module and/or sensor power.
