Error Code P073D: What It Means & What To Do?

<<See All OBD Codes

Are you looking for information on OBD P073D error code? Want to know its symptoms and causes? Keep reading. This error code occurs if the transmission is not able to shift properly. The Transmission Control Module will utilize water driven weight, an electronic solenoid to pick and hold different riggings in the transmission. At the point when the TCM distinguishes a mistake, it will tell the powertrain control module (PCM) to set code P073D.

In case you’re looking for this mistake code, it shows that your vehicle isn't going anyplace quick. On the off chance that you are stuck in neutral, it is smart thought to stop driving the vehicle, until the damage is fixed. Say, you are stuck in second gear, endeavoring to get up to interstate velocities, you may get it quicker than 60km/h. Your engine will buckle down to keep up the foreseen speed. Engine harm is highly possible in these events. The ECM (Engine Control Module) will brighten the CEL (Check Engine Light) and log an error code P073D when it identifies that the automatic transmission is unable to engage neutral.

What causes this problem with the Unable to Engage Neutral?

• Mechanical problems in transmission.
• Obstruction in transmission hydraulics.
• Damaged transmission valve body.
• Transmission control system is defective.
• Short circuit or opening in the transmission control module (TCM).
• Poor electrical connection in the transmission control module circuit.

1. Automatic Transmission Fluid - Do you find this component to be broken? Then fixing this part can help you to avoid the P073D error code.
2. Transmission Control Module - A proper functioning of the TCM can prevent your vehicle from getting stuck at the gear 6 which avoids the P073D error code.
3. Auto Transmission Shift Solenoid - A broken/ damaged/faulty shift solenoid needs immediate replacement so that you can avoid malfunctioning of the system
4. Auto Transmission Dipstick - A broken dipstick needs to be changed immediately or fixed as desired to avoid further problems.

Interested in knowing the symptoms to old code P073D? If yes, then you have arrived at the right place. We at Parts Avatar have listed out few common symptoms associated with Unable to Engage Neutral.

Common Symptoms

• Abnormality in vehicle speed.
• Decreased power.
• Abnormal engine noises.
• Decreased throttle response.
• Limited vehicle speeds.
• ATF is leaky.

Have a look at some ways with which you can correct the P073D code:

• Substituting the automatic transmission valve body kit.
• Setting the transmission control module.
• Fitting the automatic transmission fluid.
• Exchanging the auto transmission shift solenoid.
• Altering the auto transmission dipstick.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of OBD2 scanner, Auto Transmission Shift Solenoid, Automatic Transmission Fluid, TCM and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this P073D fault code:

• Validate the integrity of your ATF. With the dipstick check the level of the A/T with the vehicle running and in park. This technique varies between manufacturers. This information can be found quite easily with the service manual or even on the dipstick! Ensure that the fluid is clean and free from debris. If you don’t remember doing a transmission service, it is a good idea to check records and service your transmission respectively. Always check for ATF level on flat surface to obtain accurate readings. Make sure to use manufacturer suggested fluid.
• Find any leaks? If your fluid seems to be low, perhaps it’s leaky. Check your driveway for signs of oil stains. This can be your issue. Any way, it's a good idea to address this as well.
• Check your TCM (Transmission Control Module) for impairment. If it is located on the transmission or any other location where it may be subject to the elements, check for any signs of water intrusion. This may perhaps most definitely cause an issue like this, or any other possible issues. If you find any signs of corrosion on the housing or connectors it is also a good sign of a problem.
• If everything seems to be perfectly fine, depending on your OBD2 scanner abilities, you could screen the gear position and validate the functionality. That being said, it can be easy to identify if your transmission is shifting or not by its drivability. Is your system floored and it speeds up painfully slow? Then it is most probably stuck in a high gear (4, 5, 6, 7). Can you accelerate your vehicle fast yet the vehicle's speed never goes as fast as you like? Then it means it is probably stuck in a low gear (1, 2, 3).

Common Mistakes When Diagnosing the P073D Code

• Internal transmission defective.
• Transmission Control Module (TCM) defective.
• Transmission fluid level is reduced.
• Transmission solenoid faulty.
• Problem with wires.
