This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected that too much electricity is flowing through the part that helps the car change gears.
The transmission range select motor is responsible for selecting the appropriate gear in the transmission. If the control circuit for this motor detects a current that is too high, it can trigger this code.
The P272B code is set when the Powertrain Control Module (PCM) detects an excessively high current in the transmission range select motor control circuit. This could be due to a short circuit or an internal fault in the motor itself.
• Check Engine Light is on
• Transmission may not shift properly
• Vehicle may be stuck in one gear
• Short circuit in the wiring
• Faulty transmission range select motor
• Defective PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Check for any other codes that might be present and address those first.
• Inspect the wiring and connectors for damage or corrosion.
• Test the transmission range select motor for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the transmission range select motor if faulty.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Camry
• Honda Accord
• Ford Fusion
• Regularly inspect and maintain transmission components.
• Avoid harsh driving conditions that stress the transmission.
• Keep the vehicle's software updated.
Transmission Control Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional mechanic.
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
Check with your vehicle's manufacturer for warranty coverage on transmission components.
This code has been more prevalent in vehicles with electronic transmission controls as they age.
Moderate – It's important to address this issue soon to avoid transmission damage.
Driving with a faulty transmission can be unsafe and may lead to further vehicle damage.
• Vehicle at operating temperature
• Transmission in gear
The transmission range select motor is typically located on or near the transmission housing.
Q: Can I drive with a P272B code?
A: It's not recommended to drive with this code as it can lead to transmission damage.
Q: How can I reset the P272B code?
A: The code can be reset using an OBD-II scanner, but the underlying issue must be fixed to prevent it from returning.
