The Oil Lubrication System: What It Is, How It Works, and More
The Oil Lubrication System: What It Is, How It Works, and More Pro Tip: In a five-quart crankcase engine, running it even one quart low can cause the engine oil to break down within 1500 miles.
P0524 Code: Engine Oil Pressure Too Low
P0524 Code: Engine Oil Pressure Too LowThe engine’s internal components need a protective layer of lubricant between them. Otherwise, the metal parts that come into direct contact with each other will wear out faster and produce heat. The PCM transmits a voltage signal to the engine oil pressure sensor to use as a reference.
P0848 Code: Transmission Fluid Pressure Sensor/Switch “B” Circuit High
P0848 Code: Transmission Fluid Pressure Sensor/Switch “B” Circuit HighHydraulic fluid applies pressure inside the transmission. The transmission fluid pressure sensor converts that pressure into an electrical signal and sends it to the TCM or PCM.
P0840 Code: Transmission Fluid Pressure Sensor/Switch “A” Circuit
P0840 Code: Transmission Fluid Pressure Sensor/Switch “A” CircuitThe transmission fluid pressure sensor sends a voltage signal to the PCM, informing the computer of the hydraulic pressure within the transmission. Using this information, the PCM or TCM will control output devices, such as the pressure control solenoid.
