P0467

DTC P0467, sometimes indicated as P046700 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the auxiliary emissions system causing purge flow sensor circuit low input.

The purpose of the purge flow sensor is to detect when the engine needs to purge the fuel vapors from the charcoal canister. When the purge flow sensor detects a low input, it sends a signal to the PCM that causes the engine to purge the fuel vapors.
If the purge flow sensor is not working properly, it will cause the engine to purge the fuel vapors more often than necessary. This can cause the engine to run rich and damage the catalytic converter.
The most common causes of a purge flow sensor circuit low input are a bad purge flow sensor or a wiring issue.
If you think the purge flow sensor is bad, you can test it by unplugging it and measuring the resistance. If the resistance is within the manufacturer's specifications, the sensor is good. If the resistance is not within the manufacturer's specifications, the sensor is bad.
If you think the wiring is the problem, you can test it by unplugging the purge flow sensor and measuring the resistance between the sensor connector and the PCM connector. If the resistance is within the manufacturer's specifications, the wiring is good. If the resistance is not within the
