Code P1467 Cadillac Description
The P1467 Cadillac code indicates a problem with the EVAP (Evaporative Emission Control System) purge pump underspeed. The EVAP system is responsible for capturing and storing fuel vapors to prevent them from being released into the atmosphere. The purge pump is a crucial component in this system, as it helps to regulate the flow of fuel vapors from the charcoal canister to the engine for combustion. When the purge pump is not operating at the correct speed, it can lead to fuel vapors not being properly controlled, which can result in increased emissions and decreased fuel efficiency. If left unaddressed, this issue can also potentially lead to other problems in the vehicle's emission control system.

The P1467 code means the EVAP purge pump isn't running at the expected speed, which usually points to a faulty pump or an electrical issue like a bad connection or clogged line.
If it's just the purge pump that needs replacing, the job is fairly simple. A skilled tech can usually knock it out in about 1 hour, maybe a bit longer if there's rust or tight access. If diagnostics are needed first to confirm the pump is bad, that could add some time.
