This code means there's a problem with the part of the car that tells it which gear you're trying to use, like park or drive. It's like when a toy remote doesn't know if you want to go forward or backward.
This code is triggered when the transmission control module (TCM) detects an issue with the gear selector lever circuit, specifically with the GSL2 circuit's range or performance.
The P1868 code indicates a malfunction in the gear selector lever circuit, specifically the GSL2 circuit, which is responsible for sending signals to the transmission control module about the current gear position. This could be due to an electrical fault, such as an open or short circuit, or a mechanical issue with the gear selector lever.
• Check Engine Light is on
• Transmission not shifting properly
• Vehicle stuck in a single gear
• Faulty gear selector lever
• Damaged or corroded wiring or connectors
• Malfunctioning transmission control module (TCM)
Gear Selector Lever: The mechanism used to select the gear in an automatic transmission vehicle.
Transmission Control Module (TCM): An electronic device that controls the transmission functions in a vehicle.
• Check for any other related trouble codes.
• Inspect the gear selector lever and its wiring for damage.
• Test the continuity and resistance of the GSL2 circuit.
• Repair or replace damaged wiring or connectors.
• Replace the gear selector lever if faulty.
• Reprogram or replace the transmission control module if necessary.
• OBD-II scanner

• Regularly inspect and maintain transmission components.
• Ensure all electrical connections are secure and corrosion-free.
• Avoid harsh driving conditions that may stress the transmission.
Sensor Issue
• Take your car to a mechanic if the Check Engine Light is on.
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
Check with your vehicle manufacturer for specific warranty coverage on transmission components.
The P1868 code has been associated with vehicles experiencing transmission shifting issues due to electronic sensor failures.
Moderate – It's important to address this issue soon to avoid potential transmission damage.
Driving with a malfunctioning transmission can be dangerous and may lead to further damage. Address this issue promptly.
• Vehicle in park or neutral
• Engine running
The gear selector lever is located inside the vehicle, typically between the driver and passenger seats or on the steering column.
Q: Can I drive with a P1868 code?
A: It's not recommended to drive with this code active, as it could lead to transmission damage or unsafe driving conditions.
Q: How do I reset the Check Engine Light after fixing the issue?
A: You can use an OBD-II scanner to clear the code after the repair is completed.
