Error Code P073D is defined as Unable to Engage Neutral. This is a generic but uncommon trouble code, meaning it applies to all cars equipped with the OBD-II system, especially those made since 1996 up to present. This code normally appears to Audi, Ford, Mazda, Nissan, etc. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model to another.
Multiple modules and computers simultaneously monitor and adjust a variety of components and systems to ensure efficient and seamless operation every time a 2019 Ford Ranger is driven. One of these components and systems include the A/T or Automatic Transmission.
Inside the A/T system are numerous components, moving parts, and systems that work with each other to ensure the right operation, such as ensuring the right gear according to the driver’s need. Another important component is the TCM (Transmission Control Module), which the main function is to monitor, adjust, and correlate different values, driver’s inputs, speed, etc., and shift your 2019 Ford Ranger effectively for you. Considering the vast number of possibilities here, you would want to start with the basics.
When searching for this code, your 2019 Ford Ranger will most likely not go anywhere. If it’s stuck in gear, or can’t engage a gear, then it’s best to avoid trying to drive your 2019 Ford Ranger until it’s fixed.
The PCM will store Error Code P073D if it sees that the automatic transmission is unable to engage to neutral.
Common causes for this error code include:
First, check the integrity of the ATF. Use a dipstick (if equipped) to check the level of the A/T, with your 2019 Ford Ranger running and in the park position. This procedure may vary from one manufacturer to another. With that said, you can find more information on this in the service manual, which is sometimes in the dash or printed on the dipstick itself.
Make sure there’s clean fluid, free of any debris. If you don’t remember doing transmission service, then it’s best to have your transmission service accordingly. You would probably be surprised how dirty the ATF can affect the transmission’s functionality.
Note: To get accurate readings, make sure to check the ATF level on a flat surface. Also, use the fluid recommended by the manufacturer.
If you see leaks, and the fluid is low, then the fluid is probably going somewhere. You can check your driveway for any signs of oils or puddles.
Check the TCM for any signs of damage. If it’s in the transmission itself, or any other location where it may be subject to elements, then check for signs of water intrusion. This could lead to the problem, among other possible others. If there are signs of corrosion on the connectors or housing, then it’s a good sign of the problem.
If everything is in good condition up to this point, depending on your OBS-II scanner’s capabilities, you can monitor the position of the gear and verify its functionality. With this, by merely driving your 2019 Ford Ranger , it’s easy to say whether your transmission is shifting or not. Do you floor the gas pedal and it accelerates painfully slow? It’s probably stuck at higher gear (4, 5, 6, 7). Can you accelerate fast, yet your 2019 Ford Ranger still can’t go as fast as you’d like? Then it’s probably stuck at lower gear (1, 2, or 3).
Depending on the diagnosis, common repairs for this code include:
In terms of severity, the Error Code P073D is considered moderately high. Meaning, it must be attended immediately. Sure, you may be able to drive your 2019 Ford Ranger down the street, but it needs immediate repair to prevent further damage. AT is an intricate type of transmission, and must be kept in good shape through proper maintenance.
