This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the car's system that helps clean the exhaust. It's like when a switch in a toy isn't working right, so the toy doesn't work as it should.
The P1467 code indicates an issue with the plausibility of the battery voltages in the power switches related to the heated catalyst system.
The heated catalyst system is designed to reduce emissions by heating the catalytic converter to its optimal operating temperature more quickly. The power switches control the voltage supplied to the heating elements. This code is triggered when the system detects an implausible voltage reading from these power switches, indicating a potential fault in the electrical circuit or components.
• Check engine light on
• Increased emissions
• Failed emissions test
• Poor fuel economy
• Faulty power switch
• Wiring issues or poor connections
• Malfunctioning heated catalyst
• Battery voltage irregularities
Catalyst: A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
Plausibility: The quality of seeming reasonable or probable.
• Check the vehicle's battery and charging system for proper voltage.
• Inspect wiring and connectors related to the heated catalyst system.
• Test the power switches for proper operation.
• Use a scan tool to monitor the heated catalyst system's operation.
• Replace faulty power switch.
• Repair or replace damaged wiring or connectors.
• Replace the heated catalyst if malfunctioning.
• Ensure battery and charging system are functioning correctly.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• BMW 3 Series
• BMW 5 Series
• BMW X5
• Regularly check and maintain battery health.
• Inspect and clean electrical connections.
• Perform routine emissions system checks.
Sensor Issue
• Do not ignore the check engine light.
• Consult a professional mechanic for diagnosis.
• Regularly maintain your vehicle's electrical system.
Check with your vehicle manufacturer for emissions-related warranty coverage.
This code has been more common in vehicles with advanced emissions systems that include heated catalysts.
Moderate – Addressing this issue can prevent increased emissions and potential damage to the catalytic converter.
Driving with this code may result in failing emissions tests, which can be illegal in some areas.
• Engine at operating temperature
• Battery fully charged
The heated catalyst and its power switches are typically located near the exhaust manifold or under the vehicle.
Q: Can I drive my car with a P1467 code?
A: While you can drive with this code, it's best to address it soon to avoid increased emissions and potential damage.
Q: How can I reset the P1467 code?
A: You can reset the code using an OBD-II scanner, but it's important to fix the underlying issue first.

Fitment Required · Vehicle-fitment part
Relevant when catalyst-efficiency or emissions faults persist after proper diagnosis.
Catalyst-efficiency faults sometimes point toward converter problems after proper testing.
Catalytic converters are highly vehicle-specific and should not be purchased by code alone.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
