P0972 - OBD Trouble Code

<<See All OBD Codes

What does P0972 error code signify? What are they symptoms and causes? Is there any easy diagnosis process? This type of error code usually appears in the vehicle if the transmission refuses to shift properly. In order to control the hydraulic pressure in the transmission, the shift solenoids are used by the transmission control module. This is generally used to apply clutch in the transmission with several gear ratios, so that the vehicle moves smoothly down the road. The P0972 error will be stored, if the PCM detects an issue with pressure control solenoid.

The module that controls the transmission shift that is either the transmission control module (TCM) or the engine control module (ECM) will activate the shift solenoid valves. The TCM will activate the solenoid valve as soon as the position of gearshift is changed so that each specific gear can be operated by the transmission. As you keep selecting each and every gear, one or many solenoids will be triggered. Likewise as the gear change solenoids are disabled, other modules will be initiated.

What causes this problem with the Shift Solenoid "A" Control Circuit Range/Performance?

• The level of fluid in the transmission might be less.
  
• The transmission fluid is muddy.
• The shift solenoid ‘A’ valve is defective.
• The harness or connectors of the shift solenoid ‘A’ valve is damaged.
• There is an opening or short circuit in the shift solenoid ‘A’ valve.

1. Transmission Shift Solenoid – A proper functioning of the transmission shift solenoid is necessary to avoid P0972 error code.
2. Shift Solenoid Valve – Is this component broken or defective? Find a new replacement for shift solenoid valve from Parts Avatar.
3. Transmission Control Module – The TCM has to be damage free so that you can avoid system malfunctioning.
4. Powertrain Control Module – Replacing the defective PCM can help your system function normally.
5. Engine Control Module – A faulty or broken ECM needs quick replacement so that you can avoid P0972 error code.
6. Connectors – Visually inspect the connectors for any possible damages. Quickly replace them so as to avoid further troubles.
7. Transmission fluid – The transmission fluid has to clean without any dust particles. Replace them if they are dirty or contaminated.

We at Parts Avatar Canada care for our customers, and that’s why we will help you to diagnose P0972 code by listing out some major symptoms. They are mentioned below as follows:

Common Symptoms:

• The warning light of the service engine or the engine light remains on.
• It is impossible for the transmission to shift gears.

We have listed out some ways which would help you to correct the occurrence of OBD Code P0709. They are mentioned here as follows:

• Replacing the faulty transmission control module.
• Changing the broken wires.
• Filling the transmission with fluid to appropriate level.
• Altering the transmission shift solenoid.

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high grade solenoid, transmission shift solenoid, connectors, TCM, PCM, ECM, transmission fluid and a lot more for our precious customers.

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

• The mechanic will use a scanner to address the P0972 error code. The mechanic will then look at the freeze frame data so that he will know if there are any other trouble codes and address them as well.
• If the mechanic finds other trouble codes, he will clearly see the order in which it appears. After this, the mechanic will reset the code and test drive the vehicle to see if the codes reappear.
• If the code does not appear, then it can preferably arise due to erratic situation or any wrong detection.
• But if the code still persist, the technician will carefully inspect each of the electrical components in the transmission. He will also clearly inspect the wires and connectors to see if there are open or shorted circuits and replace the damaged component as required.
• After this, the transmission fluid will be checked. If the level of the fluid is low or dirty then it has to be checked and filled up to the correct level or replaced with clean fluid. An extremely contaminated fluid can cause severe damage to the component and it has to be replaced quickly.
• The mechanic will then use a DVOM to inspect the solenoid, circuit and as well as the harness.
• After every repairs, the mechanic will reset the code and see if the error code still exist. This will help the mechanic to know as to where the error code occurred and if it is resolved or not.

Common Mistakes When Diagnosing The P0972 Code

• Faulty transmission control module.
• The level of fluid in the transmission is low.
• Defective transmission shift solenoid.
• Issues with electrical wires.
