What is the P0692 fault number? What is the explanation of the Cooling Fan 1 Relay Control Circuit high error code? How do you fix the P0692 fault code What are the causes and symptoms of the P0692 error code?
What is the P0692? What is Fault Code? What does it signify?
If the powertrain controller module (PCM), detects an incorrect or high voltage signal within the control circuit of an electric cooling fan, the code P0692 is triggered. Some vehicles may have two cooling fans. The problem is due to the number 1 cooling fan.
Motor fans equipped with electric motors cool the radiator of vehicles. The PCM controls the temperature of the coolant temperature sensor (ECT) to turn these engines on or off. The PCM turns the fans on when the ECT reaches a predetermined temperature. The fans are turned off by the PCM when the ECT reaches a temperature within the normal range.
The PCM switches on the fans by sending ground signals through the relay to the cooling fan relay. The voltage signal will be close to the battery voltage when it is off. The voltage signal should be close zero when the relay is turned on and grounded. A P0692 code will be issued if the PCM detects a high voltage signal when turning on the fans.
P0692 fault code can affect vehicles of all makes and models, including those made by Peugeot, Citroen or Dodge, Land Rover Rovers, Ford, GMC, Volkswagen, and others.
What is the P0692 Fault Code and Why Does It Happen?
Below are some reasons to set fault code P0692:
- – Defective cooling fan relay 1
- – Defective cooling fan motor 1
- – Short-circuited, damaged, melted or broken cables
- – Corroded and/or loose electrical connectors
- – 1 blown cooling fan fuse
- – Failure of cooling fan control module (if applicable).
- – Defective engine coolant temperature sensor
- – A PCM is not working properly or has to be reprogrammed
What are the symptoms for P0692 Malfunction Codes?
You may experience the following symptoms if your vehicle has the code P0692:
- – Illumination for the check engine light
- – Not working cooling fan
- – Engine overheating
- – Air conditioner system not working properly
- – Reduced engine performance
How do I fix the P0692 fault code?
Always test the battery voltage before you attempt to solve electrical circuit problems. With the engine running, the battery voltage should be approximately 12.6V.
A blown cooling fan fuse is the most common cause for this fault code. It is important to locate the fuse and inspect it visually before removing it. If the fuse blows, the correct amperage fuse must be installed. If the fuse blows once more, you should replace it with the correct amperage fuse. The cooling fan motor may be defective if the fuse blows before the engine reaches operating temperature. If the engine is not running and the ignition switch is off, turn the fan blades manually. The fan motor must be replaced if the blades do not rotate freely.
If the fuse is working, it is likely that the cooling fan relay is the problem. There may be one relay on some vehicles, while others have two. The diagram on the fuse box cover will show you where the relay and fuses are located. You can refer to the vehicle manual for a diagram if you don’t have one. The majority of applications use a 5-pin relay. These pins are identified as 85, 86 and 87a. A multimeter can be used to verify the reliability of the relay. It is easiest to replace the relay with one that is identical. If this does not solve the problem, you should consider replacing the relay with a different one. When working with components that are hot and moving, be careful.
Note: It is important to ensure that the relay being replaced is the exact same. A wrong relay could cause damage to the PCM. Particularly Nissan vehicles have different relays, which look similar. The socket inputs may look identical, but the characteristics of the sockets can cause problems for the PCM.
There are several repairs that can resolve the P0692 fault code.
- – Replacing a defective cooling fan relay
- – Replacing an blown fuse
- Repair of short-circuited, damaged, melted, corroded or broken cables
- – Repair of damaged or rusty electrical connectors
- – Repair or replacement for the damaged cooling fan motor
- – Replace the cooling fan control unit (if applicable).
- – Test the coolant temperature sensor and replace it if it is not up to manufacturer specifications
- – Reprogramming or replacing the PCM
Rarely, though the fan motor may seem to be failing, fluid leaking from power steering can cause the problem. The hydraulic pressure of the power steering pump is part of what drives the cooling fan motor. If this happens, it can impact the fan motor’s performance. If this happens, the power steering leak must be fixed or replaced.
How serious is the P0692 fault code?
Although the P0692 code doesn’t prevent the vehicle from starting it, if the problem persists the engine could overheat and cause the air conditioner to not work properly. This code should be fixed as soon possible because of the heat damage that can cause to the engine.
