P0693: Fuel Pump Control Module (Fpcm) Circuit Low – Explained!
The P0693 fault code refers to a problem with the cooling fan 2 control circuit in the vehicle. The Engine Control Module (ECM) is responsible for grounding the low-speed relay (Fan Low relay) and the high-speed relay (Fan High relay) control circuits through a driver. The driver’s main function is to provide the ground for the component being controlled.
The ECM monitors the fault line of each driver and expects the voltage potential of the control circuit to be low (around 0 volts) when the component is commanded ON. Conversely, when the component is commanded OFF, the voltage potential should be high (near battery voltage).
If the ECM detects that the actual state of the control circuit does not match the expected state, it will trigger the P0693 fault code. In simpler terms, the P0693 fault code indicates that there is a low voltage issue in the cooling fan 2 control circuit. This can lead to problems with the cooling system, potentially causing the engine to overheat.
It is important to address this issue promptly to prevent further damage to the vehicle.
FAQ
If you’re experiencing the engine light turning on, the radiator fan becoming inoperative, and the possibility of engine overheating, it could be due to a fault code p0693. This fault code is typically caused by a faulty Cooling Fan 2 Relay, an open or shorted Cooling Fan 2 Relay harness, a poor electrical connection in the Cooling Fan 2 Relay circuit, a faulty Cooling Fan 1, or a faulty Engine Control Module (ECM). To identify the exact cause, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins.
If you’re dealing with a fault code p0693, which is causing your engine light to come on and your radiator fan to stop working, it’s important to visually inspect the wiring harness and connectors related to the Cooling Fan 2 Relay. This can help identify any issues such as an open or shorted harness, poor electrical connections, or faulty components like the Cooling Fan 1 or Engine Control Module (ECM). Take a close look for any damaged components and check for broken, bent, pushed out, or corroded pins on the connectors. Don’t forget to check the “Possible Causes” mentioned earlier as well.
If you’re experiencing the Engine Light ON or the Service Engine Soon Warning Light, along with an inoperative radiator fan and possible engine overheating, it could be a sign of a faulty Engine Control Module (ECM) contributing to the fault code p0693. Other possible causes include a faulty Cooling Fan 2 Relay, an open or shorted Cooling Fan 2 Relay harness, a poor electrical connection in the Cooling Fan 2 Relay circuit, a faulty Cooling Fan 1, or a faulty ECM. To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins in the connectors.
Wrap Up
If your engine light is on and you’re experiencing issues with your radiator fan, such as it not working or possible engine overheating, the culprit could be a faulty Cooling Fan 2 Relay, an open or shorted Cooling Fan 2 Relay harness, a poor electrical connection in the Cooling Fan 2 Relay circuit, a faulty Cooling Fan 1, or a faulty Engine Control Module (ECM).
To fix this, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins.
