17036/P0652/001618 - Sensor Reference Voltage B: Too Low Possible Causes. Wiring/Connectors from/to Intake Manifold Pressure Sensor (G31) faulty; Intake Manifold …

When a Volkswagen vehicle triggers the diagnostic trouble code P0652, it indicates that there is an issue with the sensor reference voltage 'B' circuit being too low. This sensor reference voltage is crucial for the proper functioning of various sensors in the vehicle, such as the throttle position sensor, fuel pressure sensor, and more.

The fault code P0652 in an automobile can be caused by a faulty Engine Control Module (ECM), an open or shorted ECM harness, a poor electrical connection in the ECM circuit, or a shorted sensor on the 5 volt circuit.

2016年3月24日 · What Does Code P0652 Mean? Several different sensors that are used in several different systems use a 5 volt reference voltage from the ECM to measure/monitor their systems. Some examples of these sensors are: A/C pressure sensor, MAP sensor , Camshaft position sensor, Crankshaft position sensor etc …

2024年2月14日 · The P0652 code signifies a low voltage problem in the sensor reference voltage “B” circuit, potentially affecting various vehicle sensors. This condition can lead to erratic engine behavior, poor performance, and compromised drivability. Addressing it promptly helps maintain optimal engine function and vehicle reliability. P0652 quick overview

2023年7月7日 · P0652 is a diagnostic trouble code (DTC) related to the sensor reference voltage B circuit. It is commonly found on vehicles equipped with gasoline direct injection (GDI) engines. When this code is triggered, it means that the Engine Control Module (ECM) has detected a voltage signal that is out of range for the sensor reference voltage B circuit.

2020年7月3日 · Repair Information for P0652 Volkswagen code. Learn what Sensor Reference Voltage 'B' Circuit Low means, location and how to repair?

2023年9月15日 · Diagnostic trouble code P0652 stands for “Sensor Reference Voltage “B” Circuit.” Sensors are responsible for monitoring key functions like ignition timing, fuel delivery, charging output, transmission shifting, and emission controls, among others.

2005年1月30日 · Scanned it using the OBD, found " reference sensor B low voltage" P0652. I never seen this, I suspect its' the MAF. When I looked up the MAF reading, it said 0mg. I disconnected the MAF , scanned car again, same code. Has anyone seen this? can anybody confirm that is the MAF that gives me grief ?

2020年6月27日 · Code P0652 stands for "5 Volt Sensor Reference 2 Circuit Low." It indicates that the voltage on the sensor reference 2 circuit is lower than the specified range. 2.
