P1910 – OBD-II DTC

OBD-II DTC P1910 – Pressure Control Solenoid “C” Intermittent Short

DTC P1910 meaning

DTC P1910 refers to a diagnostic trouble code indicating an intermittent short in the Pressure Control Solenoid “C” circuit. This solenoid is responsible for regulating hydraulic pressure within the transmission system, which is crucial for proper shifting and overall transmission performance. An intermittent short suggests that there may be a temporary electrical fault affecting the solenoid’s operation.

DTC P1910 symptoms

Common symptoms associated with DTC P1910 may include:

• Transmission slipping or harsh shifting
• Delayed engagement when shifting gears
• Check Engine Light (CEL) illuminated
• Reduced fuel efficiency
• Unusual noises from the transmission

DTC P1910 causes

Several factors can lead to the occurrence of DTC P1910, including:

• Faulty Pressure Control Solenoid “C”
• Wiring issues, such as frayed or damaged wires
• Corroded connectors or terminals
• Short circuits in the electrical system
• Faulty transmission control module (TCM)

DTC P1910 seriousness

DTC P1910 is considered a serious issue as it can lead to significant transmission problems. If left unaddressed, it may result in:

• Increased wear and tear on transmission components
• Complete transmission failure
• Unsafe driving conditions due to unpredictable shifting

How to diagnose DTC P1910

To diagnose DTC P1910, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the P1910 code.
2. Inspect the wiring and connectors related to the Pressure Control Solenoid “C” for any visible damage or corrosion.
3. Perform a continuity test on the solenoid circuit to check for shorts or breaks.
4. Test the Pressure Control Solenoid “C” using a multimeter to ensure it operates within specifications.
5. Check the transmission control module (TCM) for any faults or updates.

How to fix DTC P1910 step-by-step instructions

To fix DTC P1910, follow these steps:

1. Repair or replace any damaged wiring or connectors found during diagnosis.
2. If the Pressure Control Solenoid “C” is faulty, replace it with a new one.
3. Clear any stored trouble codes using an OBD-II scanner.
4. Test drive the vehicle to ensure the issue is resolved and the Check Engine Light does not reappear.
5. If the code returns, further investigation into the TCM or other transmission components may be necessary.

How to erase DTC P1910

To erase DTC P1910, follow these steps:

1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Turn on the ignition without starting the engine.
3. Navigate to the “Erase Codes” or “Clear Codes” option on the scanner.
4. Confirm the action to clear the trouble codes.
5. Disconnect the scanner and start the vehicle to verify that the Check Engine Light is off.
