This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with a part in the car that helps it shift gears automatically. Imagine if your bike's chain got stuck and you couldn't change gears smoothly.
The P0803 code is triggered when the powertrain control module (PCM) detects an issue with the control circuit of the upshift or skip shift solenoid.
The upshift/skip shift solenoid is part of the transmission system that helps manage gear changes. The PCM monitors this solenoid to ensure it operates correctly. If the PCM detects an abnormal voltage or resistance in the solenoid's control circuit, it sets the P0803 code.
• Check Engine Light illuminated
• Difficulty in shifting gears
• Transmission stuck in a single gear
• Faulty upshift/skip shift solenoid
• Damaged or corroded wiring or connectors
• Faulty PCM
PCM: Powertrain Control Module, the computer in the car that controls engine and transmission functions.
Solenoid: A coil of wire acting as a magnet when carrying electric current, used here to control gear shifts.
• Use an OBD-II scanner to confirm the P0803 code.
• Inspect the wiring and connectors related to the solenoid for damage or corrosion.
• Test the solenoid for proper operation and resistance.
• Replace the faulty upshift/skip shift solenoid.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Camaro
• Dodge Challenger
• Ford Mustang
• Regular maintenance of the transmission system
• Inspect wiring and connectors periodically
• Avoid aggressive driving that can stress the transmission
Transmission Control Issue
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
• Consult a professional mechanic for a thorough diagnosis.
Transmission components may be covered under powertrain warranty. Check with your vehicle manufacturer.
The P0803 code has been associated with issues in vehicles with manual transmissions that include a skip shift feature.
Moderate – While the vehicle may still be drivable, it's important to address the issue to avoid potential transmission damage.
Driving with a malfunctioning transmission can be unsafe and may lead to further mechanical issues.
• Engine running
• Vehicle in motion
The upshift/skip shift solenoid is typically located within the transmission housing.
Q: What happens if I ignore the P0803 code?
A: Ignoring this code can lead to transmission damage and more costly repairs.
Q: Can I drive with a P0803 code?
A: It's not recommended to drive with this code, as it may cause further transmission issues.
