P0693 - OBD Trouble Code

<<See All OBD Codes

It is the powertrain control module which detects the voltage of the cooling fan control circuit. This is done to determine if the cooling system is working properly. Now if the reading of the voltage is off by more than 10% in either direction, then it would indicate that there is an issue and thus, P0693 trouble code would start appearing.

The error code P0693 would trigger up when the powertrain control module would detect the voltage reading from the electrical cooling fan control circuit is too high or too low when compared to the parameters set by the manufacturer.

The error code P0693 can be identified as Cooling Fan 2 Relay Control Circuit Low.

What causes this problem with the Cooling Fan 2 Relay Control Circuit Low?

• There can be an open or short circuit within the cooling fan 2 relay
• Malfunctioning powertrain control module
• The cooling fan motor might be faulty
• Defective cooling fan relay
• Some electrical components might be corroded or loose
• Quirks in the engine coolant temperature sensor

1. Automatic Transmission Sensor - Do you remember when was the last time you got your car Automatic Transmission Sensor checked up? A faulty Automatic Transmission Sensor can cause a lot of issues like displaying P0693 code.
2. Electric Cooling Fan - Poor Electric Cooling Fan can cause a lot of difficulties, so why not get it replaced at time?
3. Powertrain Control Module - Are there some faults in your Powertrain Control Module? Don’t waste time and get them replaced or else P0693 code can turn up.
4. Engine Control Module - OBD Code P0693 can appear because of faulty Engine Control Module.
5. Auto Transmission Shift Solenoid - Everything is fine with Engine Control Module and still P0693 code triggering? Then you must get your Auto Transmission Shift Solenoid checked.
6. Electronic Control Unit - There can be some issues with the Electronic Control Unit due to which you may see P0693 code appearing over and over again. Visit us to buy best quality Electronic Control Unit online.
7. Radiator Fan Assembly - A lot of issues can arise do to defective griffin radiator. Did you just see P0693 code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P0693 code by mentioning some major symptoms below:

Common Symptoms

• The car engine may overheat
• Car air conditioning system may not function properly
• Flashing up of the check engine light
• Unsound radiator fan

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P0693:

• Firstly, you must replace the bad cooling fan motor
• If there is a faulty or recalled cooling fan relay, then you must replace it
• Repair an open or short circuit within the cooling fan 2 relay
• You can always replace or repair corroded or loose electrical components
• The defective engine coolant temperature sensor should be replaced
• Make sure to replace the quirky powertrain control module

Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

• An OBD-II scanner is used to detect the P0693 code
• A technician should begin with a visual inspection of all the wiring, connectors, and other components of the cruise control system
• If there are any damaged elements, then they should be replaced or repaired as necessary
• After that the code should be cleared up and perform a retest of the system
• Now if the code reappears, the technicians should activate the engine cooling fan and perform a voltage and ground test. This test can diagnose if the fan motor, or a lack of voltage is the problem.
• Then the technician should continue performing repairs, clearing the code and retesting each time, until the issue has been addressed and the code does not reappear

Common Mistakes When Diagnosing The P0693 Code

• A big mistake can be to replace the cooling fan motors directly without performing a proper diagnostic procedure
• Many a times there is some issue with the recalled cooling fan relay and that is the reason why it should be tested first before you start replacing any other parts
