This code means that there's a problem with a sensor that helps the car know how to send power to all four wheels. It's like a helper that tells the car how to grip the road better, but it's not working right.
The code C0092 indicates an issue with the position sensor B in the power transfer unit of a four-wheel-drive or all-wheel-drive system.
The power transfer unit (PTU) is a component in vehicles with 4WD or AWD systems that helps distribute power to all four wheels. Position Sensor B is responsible for providing feedback on the PTU's position to the vehicle's control module. If this sensor fails or provides incorrect data, the vehicle may not properly engage the 4WD/AWD system.
• 4WD/AWD warning light on the dashboard
• Inability to engage 4WD/AWD
• Unusual noises from the drivetrain
• Faulty position sensor B
• Wiring issues such as shorts or open circuits
• Malfunctioning PTU control module
4WD: Four-Wheel Drive
AWD: All-Wheel Drive
PTU: Power Transfer Unit
• Scan the vehicle for codes and check for C0092
• Inspect the wiring and connectors for damage
• Test the position sensor B for proper operation
• Replace faulty position sensor B
• Repair or replace damaged wiring or connectors
• Reprogram or replace the PTU control module if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford Explorer
• Jeep Grand Cherokee
• Toyota RAV4
• Regular maintenance of the 4WD/AWD system
• Inspect wiring and connectors periodically
• Address any warning lights promptly
Sensor Issue
• Avoid using 4WD/AWD until the issue is resolved
• Drive cautiously as traction may be compromised
Check with the manufacturer, as powertrain components may be covered under warranty.
This code has been more prevalent in vehicles with complex 4WD/AWD systems introduced in the last decade.
Moderate – It should be addressed soon to ensure proper vehicle handling and safety.
Ignoring this issue may lead to reduced vehicle control and increased wear on drivetrain components.
• Vehicle parked on a level surface
• Engine off and ignition in the 'on' position
The position sensor B is typically located near the power transfer unit, which is part of the drivetrain assembly.
Q: Can I drive with this code?
A: It's best to avoid using 4WD/AWD and drive cautiously until the issue is fixed.
Q: Will this affect fuel efficiency?
A: Yes, improper 4WD/AWD engagement can lead to increased fuel consumption.
