P0694: Understanding The Fuel Pump Control Circuit Low Fault Code
The P0694 fault code refers to a problem with the Cooling Fan 2 Control Circuit.
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.
When the ECM commands a component to turn on, the voltage potential of the control circuit should be low, around 0 volts. Conversely, when the ECM commands the control circuit to turn off, the voltage potential should be high, close to battery voltage. If the ECM detects that the actual state of the control circuit does not match the expected state, it will trigger the P0694 fault code.
This code indicates that there is a high voltage condition in the Cooling Fan 2 Control Circuit. It is important to address this issue promptly to ensure proper cooling system operation and prevent potential engine damage.
FAQ
If you’re experiencing the fault code P0694, you may notice a few symptoms. First, the engine light or service engine soon warning light will be illuminated. Additionally, you may find that your radiator fan is not working properly, which can lead to possible engine overheating. The most common cause of this fault code is a faulty cooling fan 2 relay or a problem with the cooling fan 2 relay harness. It’s also possible that the cooling fan 1 is faulty or there’s an issue with the engine control module (ECM). To fix this issue, you’ll want to visually inspect the wiring harness and connectors, checking for any damage or corrosion.
If you’re experiencing the p0694 fault code, you might notice that your engine light is on or that your radiator fan isn’t working properly. This could potentially lead to engine overheating, which is definitely something you want to avoid. The cause of this fault code 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 even a faulty engine control module (ECM). To fix the issue, you’ll want to visually inspect the wiring harness and connectors, checking for any damage or corrosion. It’s also a good idea to look for any broken, bent, pushed out, or corroded pins in the connectors.
