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).
