Guide To P0467 OBD Error Code Solutions

<<See All OBD Codes

The Purge Flow Sensor is generally found mounted in the evaporative fuel system, which is also known as charcoal canister, which is close to the fuel tank.

The trouble code P0467 code can be described as Purge Flow Sensor Circuit Low Input.

Want to learn something more about this fault code? This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model.

What causes this problem with the Purge Flow Sensor Circuit Low Input?

• The purge flow sensor might have some flaws
• Purge flow sensor harness might be opened or shorted
• There can be bad electrical connection in the purge flow sensor circuit

1. Fuel Injector - Do you remember when was the last time you got your car Fuel Injector checked up? A dirty Bosch Fuel Injectors can cause a lot of issues like displaying P0467 code.
2. Engine Control Module - Are there some faults in your Engine Control Module? Don’t waste time and get them replaced or else P0467 code can turn up.
3. Fuel Pump - OBD Code P0467 can appear because of faulty Carter Fuel Pump.
4. Electronic Control Unit - Everything is fine with Engine Control Module and still P0467 code triggering? Then you must get your car ECU checked.
5. Powertrain Control Module - There can be some issues with the Powertrain Control Module due to which you may see P0467 code appearing over and over again. Visit us to buy best quality PCM online.
6. Injector Pump - A lot of issues can arise do to defective Injector Pump. Did you just see P0467 code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.
7. High Pressure Fuel Pump - It is an important auto part which needs full care. A faulty Holley Fuel Pump can be a reason behind the flashing up of P0467 code.

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P0467:

• If there are some faults in the purge flow sensor, then it should be replaced
• Repair or replace the opened and shorted purge flow sensor harness
• The bad electrical connection in the purge flow sensor circuit should be repaired

Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

The first step should always be a technical service bulletin search for your particular vehicle. The vehicle manufacturer may have a PCM flash/reprogram to cover this issue, and it pays to check on this before you find you’ve gone down a wrong path

The next step would be to locate the purge flow sensor on your particular vehicle. This sensor is usually found mounted in the evaporative fuel system, also known as the charcoal canister, close to the fuel tank or possibly even in the top of the fuel tank / fuel pump module

Now once it has been located, then you should visually inspect the connector and wiring. Look for scraping, rubbing, bare wires, burn spots or melted plastic. Pull the connector apart and carefully inspect the terminals inside the connector. Check if they look burned or have a green tint indicating corrosion. Use electrical contact cleaner and a plastic bristle brush if cleaning of the terminals is needed. Let dry and apply electrical grease where the terminals contact

If you have a scan tool, then you should clear the diagnostic trouble codes from memory, and see if P0467 code returns. If it does not, then there is definitely some issue in the connections

If the P0467 code does return, we will need to test the PFS sensor and its associated circuits. With the Key Off, disconnect the electrical connector at the PFS sensor. Connect a digital voltmeter black lead to the ground terminal at the PFS sensor wiring harness connector. Connect the red lead of the digital voltmeter to the power terminal at the PFS sensor wiring harness connector. Turn Key On Engine Off

Check manufacturer’s specifications; voltmeter should read either 12 volts or 5 volts. If not, repair the power or ground wire to the sensor, or replace the powertrain control module

If the prior test passed, then there would be a need to test the signal wire. With the connector still disconnected, move the red lead of the voltmeter from the power wire terminal to the signal wire terminal. The voltmeter should now read 5 volts. If not, repair the signal wire, or replace the PCM

If all prior tests have passed and you continue to get a P0467, this would most likely indicate a failed PFS sensor, although a failed PCM could not be ruled out until the PFS sensor had been replaced.

If you are unsure, then you should definitely seek assistance from a trained automotive diagnostician. PCMs must be programmed, or calibrated to the vehicle in order to be installed correctly
