This summary uses the existing diagnostic information shown in full below.
This code means that a sensor in the car that helps tell the computer if the car is in park is not working right. It's like when a toy's on/off switch gets stuck.
The P271B code indicates that the voltage in the Park Pawl Position Sensor A circuit is higher than expected, suggesting a possible electrical issue.
The Park Pawl Position Sensor A is responsible for detecting the position of the park pawl, a component that locks the transmission in place when the vehicle is in park. A 'Circuit High' condition suggests that the sensor is sending a higher-than-normal voltage signal to the vehicle's Powertrain Control Module (PCM), which could be due to an open circuit, a short to voltage, or a faulty sensor.
• Check Engine Light illuminated
• Vehicle may not engage park properly
• Transmission may not shift correctly
• Faulty Park Pawl Position Sensor
• Wiring issues such as open or short circuits
• PCM (Powertrain Control Module) malfunction
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code
• Inspect the wiring and connectors for damage
• Test the Park Pawl Position Sensor for proper operation
• Replace the Park Pawl Position Sensor if faulty
• Repair or replace damaged wiring or connectors
• 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
• Ensure electrical connections are clean and secure
• Follow scheduled maintenance for the vehicle
Sensor Issue
• Avoid driving the vehicle until repaired to prevent further damage
• Consult with a professional mechanic for accurate diagnosis
Check with your vehicle manufacturer for warranty coverage on transmission components.
This code has been associated with transmission sensor issues in vehicles with electronic control systems.
Moderate – It is important to address this issue soon to avoid potential transmission damage.
Driving with a malfunctioning park pawl sensor can lead to transmission issues, which may pose safety risks.
• Vehicle in park
• Engine running
The Park Pawl Position Sensor is typically located on or near the transmission housing.
Q: Can I drive with a P271B code?
A: It's not recommended to drive with this code active, as it may lead to transmission issues.
Q: How do I reset the P271B code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, further diagnosis is needed.
