Easy Diagnosis Of Engine Error OBD Code P073F

Here are some steps which you should follow in order to diagnose this P073F fault code:

 

  • Initially you have to check the integrity of ATF. By using the dipstick check its level while running and when your vehicle is idle. The process varies a little between different manufacturers. However, this information can be easily found with the help of service manual of the vehicle or it will be printed in the dick. Ensure that the fluid is new and free from rubbles. If you don’t remember doing a transmission service, it is always good to check for records and service the transmission accordingly. You will be surprised to know how dirty the ATF can affect the functionality of your vehicle’s transmission. Always check ATF level on flat surface to obtain accurate readings. Ensure that you use manufacturer suggested fluid.
  • Do you find any leaky areas? If your fluid is low, then it's probably because of the leak. Check your driveway for any signs of any oil tints or puddles. You may not realize, but this can be your issue. Either way, it's a better idea to address them as well.
  • Check for injuries in the transmission control module. If there is damage in the component itself or elsewhere, where it may be subject to the elements, visually check them for any signs of water interruption. This can more likely cause a problem in many possible ways. If you find any signs of corrosion on the housing or the connectors, they are a better indication of the problem.
  • If everything seems to be perfectly fine, based on the capability of the OBD 2 scanner, you have to check for the gear position and check for its functionality. If will be easy to let you know, if your transmission is shifting or not by its drivability. Is it floored and keeps accelerating extremely low? Then it could have been stuck at the high gear (4, 5, 6 and 7). You’re able to accelerate it as fast as possible yet the vehicle's speed never goes as high as you expect? Then it’s probably stuck in a low gear (1, 2, 3).
