P0976 - OBD Trouble Code

<<See All OBD Codes

How do you know that the P0976 error code is stored in your vehicle? What are its symptoms and causes? The P0976 error code occurs if the shift solenoid control circuit is low. The shift solenoids are usually used by the transmission to control hydraulic pressure so that it supplies the different gear ratios for your vehicle to propel efficiently along the road as you apply the clutch pack. In case, the pressure control solenoid does not work properly, the P0976 error code will be set.

The shift solenoid valves are turned ON/OFF only when the engine control module commands the gear shifts. The ECM will find out the problem if there is an opening or short circuit in the shift solenoid valve. When this problem occurs the engine light will be illuminated and the error code will be stored in the vehicle. In this situation, the failsafe function will be executed by the ECM and the rest of the shift solenoid valves will be turned ON/OFF to good condition.

What causes this problem with the Shift Solenoid "B" Control Circuit Low?

• The transmission fluid level might be reduced.
• Murky transmission fluid.
• Malfunctioning shift solenoid ‘B valve.
• Either the harness or connectors of shift solenoid ‘B valve is defective.
• There is an opening in the shift solenoid ‘B’ valve or the circuit is shorted.

1. Engine Control Module – Replace or repair the faulty engine control module so that you can avoid the P0976 error code getting stored in the vehicle.
2. Transmission Fluid – Carefully inspect the transmission fluid if it is dirty or muddy. If so, replace them with clean fluid.
3. Transmission Control Module – Is your transmission control module broken or damaged? Are you looking for a replacement? Then find the right replacement from Parts Avatar at best prices online.
4. Connector - A broken or faulty connector can cause trouble to your vehicle. Replace them as soon as possible so that the P0976 error code can be resolved.
5. Transmission shift solenoid – Transmission shift solenoids have to be damage free or defective free for the system to function normally. If it is damaged replace them as soon as possible.

Interested in knowing the symptoms to OBD code 0976? If yes, then you have arrived at the right place. We at PartsAvatar have listed out few common symptoms associated with this fuel injector problem.

Common Symptoms

If there is a P0976 error code, the vehicle will experience slipping of gear or it will fail to shift. As the solenoid control circuit malfunctions, one or more gears which is present in the vehicle will become inaccessible. In some cases, the transmission system will start behaving erratically based on how severely the solenoid control circuit is damaged. In order to diagnose this issue, you will have to find out this trouble code and you will find the engine lamp in the dashboard illuminated.

We have listed out some ways which would help you to correct the occurrence of OBD Code 0976. They are mentioned here as follows:

• Any wires that have been damaged, eroded or separated has to be quickly replaced or repaired.
• The faulty solenoid has to be changed immediately.
• Any faulty component in the vehicle needs a quick replacement.

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high-grade engine control module, transmission fluid, transmission control module, hydraulic pressure, connector, transmission shift solenoid and a lot more for our precious customers.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0976 code to be stored:

• As a first step, the mechanic will use a scanner or an OBD II code reader to identify the P0976 error code.
• Carefully inspect the solenoid for any possible damages or disconnections.
• The circuit has to be carefully checked between the shift solenoid control and the PCM with the help of a voltmeter.
• This will help the mechanic to locate the circuit issue in the vehicle if there was any.
• Make sure that every connector is properly connected and carefully note down the wires which are damaged, eroded or else broken.

Common Mistakes When Diagnosing The P0976 Code

• Malfunctioning of the transmission control module (TCM).
• The level of fluid in the transmission might be very low.
• The transmission shift solenoid might be faulty.
• There is some problem with wires.
