Error Code P0719: What It Means & What To Do?

<<See All OBD Codes

Do you know when your system will indicate P0719 error code? What does this error code indicate? When there is a P0719 error code in the powertrain control module, it will show you that there is an abnormal voltage reading from the brake switch of the B circuit.

The torque converter clutch system has the brake switch b circuit as its part. It generally indicates the status of the brake pedal, and works as if it is the part of the system and then deactivates both the cruise control and the torque converter lock-up. If the engine control module identifies an abnormal reading from the brake switch, then the P0719 error code will be stored.

What causes this problem with the Torque Converter/Brake Switch B Circuit Low?

• There is an open, shorted, or corroded wire in the system.
• Presence of on opening, shorted or corroded electrical components in the system.
• The bulbs are blown.
• The brake lamp is not properly adjusted.
• The bulb sockets are damaged. Faulty or broken.
• And in very rare case, there is a faulty PCM.

1. Brake Switch - Broken or damaged brake switch needs to be immediately replaced in order to avoid this error code appearing in your vehicle.
2. Torque Converter Clutch - Are you looking for this replacement part? Find them easily at Parts Avatar at the best prices online.
3. PCM - a faulty or damaged power control module is the reason for the error code to be stored in the system. Replace this component to get rid of this error code.
4. Cruise Control Connector - Do you find this component to be broken or damaged? Replace them immediately to avoid further troubles.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P0719 code by mentioning some major symptoms below:

Common Symptoms

• The brake lamps will either turn off or they will not illuminate.
• Torque converter does not lock properly.
• The lock of the torque converter will not unlock.
• The vehicle will delay when it comes to a full-stop.
• Other torque converter and its related clutch codes are more likely to be stored in the power control module along with this error code.
• The check engine light of the vehicle is too bright.

Have a look at some ways with which you can correct the P0719 code:

• Replacement of the defective / damaged/ broken brake lamp switch.
• Replacement of the blown fuse lamp.
• Fixing or replacement of the shorted, corroded or opening in the electrical connectors.
• You have to adjust the misadjusted brake lamp.
• Repairing or fixing the defective, broken or damaged bulb sockets.
• And in a very rare case you have to replace the defective PCM.

However, if you face any issue then we have stocked a wide range of best priced brake switch, torque converter clutch, brake switch, Power control module, cruise control and more to help you out in fixing your car.

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

• After properly diagnosing with a scan tool, if there is a P0719 error code in the system, then the technician will start with a visual inspection of all the wires, connectors and other related components of the torque converter system. If there are any damaged components they must be replaced, reconnected or repaired as required. You should then clear the codes and retest the vehicle, making sure that the check engine light does not appear again.
• If the check engine light appears again, the mechanic will check for both the battery voltage with a digital Volt/ ohmmeter on the inner and outer sides of the brake lamp switch and check for continuity. If there are any open or shorted circuit, they must be repaired. If the voltage is found in the inner side but no on the outer part of the brake lamp switch, then it indicates that the brake lamp switch is broken or faulty. It a common cause of this code.
• If not so, then the technician will continue to check for signals between components, damaged or loose electrical components, and carrying out other repairs as required until it is sort out.

Common mistakes when diagnosing the P0719 code

When you diagnose the error code P0719, the common misdiagnosis can be the locked - up solenoid or the wires, rather than checking the components like lamp switch, the lighting controller, or the brake lamp connectors and circuitry.
