What Does Check Gauges Mean?The check gauge light is usually triggered once the PCM detects something reading that’s outside normal parameters. These readings include:
Coolant TemperatureEngine RPMFuel LevelOil PressureTransmission temperatureTire PressureWheel SpeedVoltmeter
Common Triggers of the Check Gauges Light
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.
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.
How to Check the Oil Pressure ManuallyIn an emergency, you can use street parking as a workspace to check your vehicle’s oil pressure, as long as the parking slot is flat enough. Before you try this, however, consult your city’s laws to determine if it’s legal to use street parking for car maintenance and repair jobs.
