The car's computer isn't getting enough power from one of its main power sources, which can make it act funny or not work right.
The P167F code indicates that the internal control module has detected a low voltage condition in the 5-volt reference circuit, which is crucial for the proper operation of various sensors and components.
The 5-volt reference circuit supplies power to various sensors and components necessary for vehicle operation. A low voltage in this circuit can cause incorrect sensor readings and lead to improper engine performance or other operational issues.
• Check Engine Light is on
• Engine stalling or misfiring
• Poor fuel economy
• Faulty alternator or battery
• Damaged wiring or connectors
• Faulty control module
Control Module: The computer that manages various functions of the vehicle.
5-Volt Reference Circuit: A circuit that provides a stable 5-volt power supply to sensors and components.
• Check battery and alternator voltage output
• Inspect wiring and connectors for damage
• Test the control module for faults
• Replace or repair damaged wiring

Electrical Issue
• Avoid driving long distances until repaired
• Have a professional diagnose the issue
• Regular maintenance can prevent recurrence
Check with your vehicle manufacturer for specific warranty coverage related to electrical components.
This code has been reported in various vehicle models and is often associated with battery or alternator issues.
Moderate – Address the issue soon to avoid potential engine performance problems.
Driving with this code active can lead to safety issues due to potential engine stalling or misfiring.
• Vehicle ignition in the ON position
• Engine running at idle
The control module is typically located under the dashboard or in the engine compartment.
Q: Can I drive with a P167F code?
A: It's not recommended to drive for long periods with this code, as it can lead to engine performance issues.
Q: What happens if I ignore the P167F code?
A: Ignoring this code can lead to worsening engine performance and potentially leave you stranded if the engine stalls.
